# Math and Science

## October 19-October 23

This week in Mathematics, students will be doing an error analysis of their Multiplying Fractions quiz. Students will use the error analysis template to identify their growth areas as well as correct their mistakes. Students will then begin dividing a whole number by a fraction using an area model. Students will be building off their understanding of using an area model to multiple fractions.

This week in Science we will wrap up our discussion of buoyancy Monday. We will have a quiz on Tuesday that will cover buoyancy as a force, how it relates to density, and how we can determine if things will float or sink. The rest of the week will be discussing compressibility and how this relates to a Cartesian diver (in class demo), as well as what pressure is and how we can calculate it as a ratio of force in a given area.

## October 13- October 15

This week in Mathematics, students are revising for their Multiplying Fractions quiz on Thursday October 15th 2020. It’s important students know how to multiply a fraction by a whole number and a fraction by a fraction using various strategies. These include using an area model, a number line and the product method. Please remind students to check D2L and PowerSchool if they are absent from school so they can stay up to date.

In science we are exploring the concept of buoyancy. What it means as a quantifiable force and how it relates to density. This will culminate in a building project where we build and test the buoyancy of different boat designs to determine what will hold the greatest weight.

## October 5 - October 8

This week in Mathematics, students will be learning how to multiple a fraction by a fraction using area models, counters and number lines. It’s important students continue to practice converting between improper fractions and mixed numbers, as well as simplifying fractions to their lowest form.

This week in Science we are exploring the concept of density. We will be building our skill of using triple balance beam balances to measure mass, using rulers to calculate volume and putting them in a ratio that quantifies density of different materials. We will look at the how states of matter and particle size influence density as well.

## September 21- September 24

This week in Grade 8 Mathematics, students will be revising how to add fractions with both common and uncommon denominators. This will help students understand the concept of repeated addition that leads into multiple fractions. A reminder that if your student is away, please check D2L and PowerSchool as they are updated regularly with the resources your student may have missed.

This week in Science we will be calculating concentrations of solutions and creating a graph to compare the solubility of different substances. We will have a short quiz Thursday on all concepts covered so far.

## September 14 - September 18

This week in Grade 8 Mathematics, students will be diving into working with fractions. At the end of this unit, students will be able to add and subtract fractions (from Grade 7), as well as multiple and divide fractions (new in Grade 8). To prepare students, teachers will be touching on previous skills such as equivalent fractions and finding common denominators.

This week in Science we will be reviewing the particle model. This will lead us into determining the difference between pure substances and mixtures and will be followed by demonstrations to determine factors which affect the rate of dissolving.

## September 8-September 11

This week in Grade 8 Mathematics, students will be introduced to some basic math problems to get their brain thinking about numbers again. These are problems basic around basic operations (addition, subtraction, multiplication and division) as well as fractions and percents. Through out the year, students will complete a number of pre-assessments to help guide teaching and learning in the classroom and later in the week, students will complete their first one on fractions.
