Math: Week of September 12

Welcome to Grade 9 Math!

Much of this year’s program will focus on the application of concepts covered in grade 7 and 8. Over the past two years, students have covered operations involving fractions and integers; this year we will combine those two and work with rational numbers. We will continue to build our understanding of linear relations, square roots and equation solving. Also, grade 9 is the beginning of many more abstract concepts, in preparation for high school, such as exponents and polynomials.

During this first week, we have investigated powers and exponents. We have looked at the parts of a power and how exponents are a short cut for repeated multiplication.

From time to time, there will be support videos and practice posted here to assist students with the concepts in which we are covering. For work with exponents:

Math: Week of September 19

Grade 9s are finishing up their introductory work with exponents.  We will be moving in to a study of exponent laws.  These are very important for further studies this year in polynomials as well as math in grade 10.

Math: Week of October 17

Grade 9s have finished up their work with exponents for the time being.  Next, we have begun to move in to square roots.  Students will have some prior knowledge of square roots from grade 8, but this year the focus will be on square roots of fractions and decimals.

The grade 9s have begun working with Linear Relations.  Last year, most of the focus was using a table of values (also known as a t-chart).  This year, students should be able to look at creating expressions from the pattern within the t-chart in order to make further predictions.  Once complete, we will use the data from the t-charts to create x and y graphs.  The biggest change from grade 8 is the introduction of horizontal and vertical lines and the equations that create these.
