After the spring break, we will be moving into Rational Numbers.  To best be prepared for this, students should have a good knowledge of addition, subtraction, multiplication and division of both integers and fractions from their grade 7 and 8 years.

### March 22 - 26

Math:  As most classes have finished up Polynomials this past week, we begin the move towards spring break with an easier concept for many.  Grade 9s will be exploring line and rotational symmetry.  These two concepts are similar to what they have done in the past as it relates to symmetry from elementary

Science:  Students will be wrapping up their investigation on how acids, bases, and various other chemicals impact air, water, and soil quality. We will then explore some performance tasks designed to mimic the style of written questions which will appear on the final unit exam. At the end of the week, students will write their unit exam for Environmental Chemistry.

### March 15 - 19

Math:  Grade 9s will be looking at continuing with multiplication and division of polynomials.  Students can expect a quiz during this week that cover these concepts.  For extra support with these two operations:

### March 8 - 10

Math:  As we enter this short week, grade 9s will start getting into the multiplication and division of polynomials.  Like adding and subtracting, the better the understanding of integers, the more success one will experience with polynomials.  So, continue to better your accuracy and speed with integers because it will pay off with polynomials.

Science:  Students will continue to practice scientific graphing. Various data sets and types of graphs will be produced. An assessment of this foundational skill will occur prior to parent teacher conferences.

### March 1 - 5

Math:  Over this past week, we have spent time focusing on polynomial addition.  Our attention will now shift to subtraction.  Students have begun to find that a solid understanding of integers is crucial.  As a result, here is some support for your child with integers:

### Feb 16-19

Math:  Grade 9 math will continue with it’s work of polynomials.  We will move from our introductory work of finding the number of terms, classifying polynomials and finding the degree.  Our attention will be devoted to representing polynomials with algebra tiles and how to recognize like terms, both pictorially and symbolically.

For extra support:

Science:  This week in science, students will continue exploring the various forms of natural/man-made pollution on earth, how they are created, and possible solutions to these environmental issues. We will then look into how these chemicals magnify within living things and ultimately harm them.

### Feb 8-10

Math:  Now that circle geometry has been completed, grade 9s will be diving into Polynomials.  This area of study uses many important concepts that are necessary moving forward into high school.  For a student to be successful, it is recommended that they have a strong understanding of integers moving forward.  Polynomial concepts use addition, subtraction, multiplication and division of integers constantly, so a strong understanding is beneficial.  What is a polynomial?  Watch: https://www.khanacademy.org/math/algebra/x2f8bb11595b61c86:quadratics-multiplying-factoring/x2f8bb11595b61c86:multiply-monomial-polynomial/v/polynomials-intro

### Feb 1-5

Math:  This week, grade 9s will be finishing up their circle geometry with a quiz on the tangent line.  This will lead to a circle geometry post-assessment to gauge each student’s growth in the subject area.  Now that we have completed circle geometry, we will begin our work with Polynomials.  We will start with a pre-assessment to support students with the prerequisite skills required before beginning our work with Polynomials.

Science:  Grade nines will begin studying the next unit in Science 9: Environmental Chemistry! We will begin with a preassessment to determine which concepts were remembered from previous years, and which must be focused on. Following this, students will begin looking at persistent organic pollutants and the different compounds which aid living things.

### Jan 25-28

Math:  As we enter the last week of January, circle geometry is wrapping up.  We will investigate our last concept – a tangent line.  Much like chords, the tangent line will be used to create a right triangle so that we can use the Pythagorean Theorem.  As a result, we will have a final quiz on tangents, but will not have a unit final this time.

### Jan 18-22

Math:  During the upcoming week, grade 9s will continue to finish up their work with inscribed and central angles as well as chord properties.  A quiz will follow around mid-week.  The final concept that will be covered in circle geometry will be tangent lines which will begin at the end of the week.

Practice here:

Science:  Grade 9's will continue practicing their ability to name ionic and molecular chemical compounds and identify different types of chemical reactions.

### Jan 11-15

Math:   Grade 9s will continue to investigate properties of angles and chords within a circle.  Upon the completion of each investigation and practice, there will be a short assessment to gauge student understanding.  Students should be looking at finishing up circle geometry by the end of the following week.

Science:  Students will be wrapping up their Interesting Chemical Compound Research Project. Following this, students will continue exploring the types of chemical reactions common in nature, and their applications to industry and science.

### Jan 5-8

Math:  During the first week of January, grade 9s will be beginning their work with Circle Geometry.  We will delve into 3 main concepts that will allow us to solve problems involving circles.  It is necessary that students bring some prior knowledge regarding angles and the Pythagorean theorem.

Science:   Grade nines will review their naming of ionic and covalent chemicals, knowledge learned from before the break. Once prior knowledge has been reviewed satisfactorily, they will move on to learning about the different reaction types we see in chemistry.

### Dec 14-18

Math:  As we enter the final week before the winter break, we are continuing our work with linear relations.  Most time will be spent graphing relations as well as interpreting the data.  Students will be introduced to interpolation and extrapolation.  Towards the end of this final week, grade 9s can expect a quiz on what has been covered so far with linear relations.

For extra support, watch these:

Try these:

Science: Students will continue to focus their efforts on understanding ionic and covalent/molecular compounds, their similarities and differences, and how we as chemists name and write formulas for these compounds. Students will have another quiz on these understandings on Tuesday or Wednesday. We will then begin to work on using this knowledge to identify different types of chemical reactions.

### Dec 7-11

Math:  After a successful first week for so many of us, we are going to change our focus from t-charts and expressions and bring in graphs.  We will look at graphing lines on the coordinate grid by using the tables of values and equations.  We will also begin to explore predictions using the pattern of the relation, also called extrapolation and interpolation.

Science: We will continue learning about chemistry by exploring the differences between chemical and physical properties. Using our knowledge of atomic structure, we will then begin creating and naming ionic and covalent compounds.

### Nov 30-Dec 3

Math:  It looks like we are going back to a form on learning from home, online.  Not to worry.  We can guarantee that math instruction will not change and all students will have the same opportunity to ask questions of their math teacher.  During this first week from home, we will be looking at creating expressions from patterns using a Secret Pattern Challenge as well as some work time.  Students are encouraged to complete everything within the online class period if they are able to stay focused on the task.  Later in the week, we will be looking at some work with tables of values.

### Nov 23-27

Math:  Now that we have begun to conclude our work with square roots (including a post-assessment and unit final), this next week will bring about an area of study that students have experience with from previous grades – Linear Relations.  Linear relations is mainly the studying of patterns and expressing those patterns in various ways.  Once we have completed a pre-assessment, we plan to begin to study the relationships between those various ways which include tables of values, graphs, equations and problems.

### Nov 16-18

Math:  As we head into a shortened week, we are also wrapping up our squares and square root work.  Students can expect a final assessment as well as their post assessment in the coming week.  After the parent-teacher interviews, we will be moving into linear relations.  This will be building on the concepts that students covered in grade 8.

For additional practice with square roots:  Watch these:

Try these:

Science:   We will be transitioning to our largest and most important unit of the year: Chemistry. This unit will include exploring matter and chemical change. A baseline of knowledge will be uncovered using open-ended questions to see what students have retained from last year.

### Nov 9-13

Remember no school on Nov. 11th

Math:  We will be continuing to estimate square roots of non-perfect squares, including fractions and decimals.  It would be helpful for students to know their perfect squares (at least to 144) as it does promote confidence and speed in their work.  This work is meant to be done without a calculator as it promotes numeracy skills that are of the utmost importance in high school.

Science:  Students will complete their final day of biodiversity review through a Kahoot! online practice quiz. Our science exam will then be completed in two parts: multiple choice on Tuesday and written questions Thursday. The week will then be wrapped up with an introduction to our next unit!

### Nov 2-6

Math:  We will be continuing to work with square roots of fractions and decimals, both using models as well as without the use of a calculator.  There will be a lot of opportunity to practice and receive the individual attention required to move forward.  Because this is a short concept, students can expect a test the following week (week of November 9).

Science: This week in science students will finish their exploration of the 6th mass extinction, its causes and effects, and how humans are working to stop it before irreparable damage is done to the Earth's biodiversity. They will also begin reviewing for our cumulative unit final, which will be taking place next week.

### October 26-29

Math:  Now that powers and exponents have been completed, we will be moving in to our new area of study…square roots.  Last year, grade 8s studied square roots of whole numbers and estimated the value of a square root.  This year, our square root time will be spent mainly with decimals and fractions.  Expect a pre-assessment early in the week followed by getting in to the square root content.

Science:  This week students will finish off the biodiversity unit through exploring invasive species and their impacts on native habitats. The 6th great extinction will also be explored, including its underlying causes and methods to combat this loss of diversity.

### October 19-23

Math:  We have concluded covering all topics involving powers and exponents.  As a result, during the coming week, we will review the material in preparation for our first unit final on Thursday, October 22.  When we first began our work with powers and exponents, we completed a pre-assessment to see the areas in which each students had strengths and areas of need.  Now that we have addressed those and the grade 9 material, we will conduct a post test to gauge the learning that has taken place.

Science:  students will continue to explore genetics and how heritable traits are passed from generation to generation. They will create their own unique dragons by randomly assigning alleles using various patterns of dominance and interpreting these to describe what the dragon would grow up to look like. This lab will be due next week. Students will also have an assessment on genetics towards the end of the week.

### October 13-16

Math:  During the upcoming short week, we will continue to work on the second set of exponent laws.  Students should expect a quiz towards the end of the week as we conclude our work with powers and exponents.

Science:  Students will continue their exploration of chromosomes and chromosomal abnormalities through the analysis of 4 sets of 46 human chromosomes. This Karyotyping activity will allow us to then transition into the genetic analysis of genes, their alleles, and traits that show dominant/recessive expression. Students should expect an assessment on these concepts towards the end of the week.

### October 5-8

Math:  During this next week, grade 9s will continue with the exponent laws.  Expect a quiz at the end of the week covering the exponent laws over these two weeks.  By completing the exponent laws this week, we have covered all concepts related to exponents this year so students should be expecting a unit final in the coming weeks.

For additional practice with the exponent laws covered this past week:

### September 28 - October 2nd

Math:  Now that we have completed the introductory components of exponents, we will move into the exponent laws.  These 5 laws are foundational skills for success in high school.  The best way to master these skills are to practice continually.

Science:  This week in science grade nines will be learning about the behavioral and structural adaptations which allow organisms to survive and thrive in their respective environments. We will then move into reproductive strategies and the genetic advantages/disadvantages behind these strategies.

### September 21-24

Math:  Over the past week, we have looked at the various parts of a power and what those parts mean.  We have completed some basic calculations with powers.  In the coming week, we will continue with the evaluation of powers.  However, this will begin to look more difficult as we will be bringing in multiple operations.  Thus, students will need to access past knowledge – order of operations.  For extra support with the exponent work that we have covered, look at:

Written Explanation:

Extra Practice:

Science:  This week in science students focused on increasing their understanding of biodiveristy. Within this, the variation within a single species and between species was explored. The exact mechanism by which natural selection and ultimately evolution operate was also elucidated. Finally,  students explored examples of symbiotic relationships and how they affect the species involved. An assessment on these outcomes will occur in the middle of next week.

#### September 14-18

Math:  Grade 9s will begin the week with the MIPI (Math Intervention Programming Instrument) to assess what they know from their grade 8 year.  This will give us data that will be used at the end of the school year.  At that time, students will take another MIPI to assess their understanding at that time.  If the two scores are consistent, the student has learned what was required of them over the course of their grade 9 year.

We will also begin our work with powers and exponents.  It is important that students learn their new math terminology during this week (such as power, base, coefficient, etc).  We will lead into the meaning of an exponent and how to evaluate powers.

Science:  This week we are starting the biodiversity unit by doing a hand size lab looking a species variation.  We will be exploring diversity between species, different environmental factors and structural/behavioural adaptations.  At the end of the week there will be a small assessment on these outcomes.

#### September 8-11

Math:  Welcome back grade 9s!  During this coming week in math, we will begin to find out a bit more about each student.  We would like to know each student’s strengths and weaknesses so that we know where to best help them during the year.  There will be come pre-assessments to discover what they know from the past so as to best move forward with their learning this year.  Along the way, each day will be some problems to get them talking and thinking math.  We look forward to a great year from all our grade 9 students!

Science:  This week in Science we will be going over lab safety rules and procedures. We will follow that by reviewing and building upon the fundamental science skills of determining variables in experiments and how to convert between different units of measurement.
