Math with Mrs. Neal and Ms. Bonter

Just a quick update to let you know we have started working on multiples and factors in math. We have explored prime and composite numbers, as well as divisibility rules. The Grade 7s have started Chapter 1 Factors and Exponents in the Nelson workbook. The Grade 6s are working on Chapter 6 Multiplication and Division which also starts with multiples and factors. The Link for the Nelson website which has some extra practice is here:

With Mrs. B, students are still working on measurement of 2D shapes (and nets). The tests from last week will be going home this week. If incorrect questions are revisited, bonus marks will be given. There will be a retest next Wednesday or Thursday for those students who are interested in raising their mark.

The specific expectations we're working on are posted below:

Knowledge -uses the appropriate formulae to solve perimeter #1 a, b -correctly uses units of measurement and can differentiate between precise and estimated measurements #2, 3 -uses the appropriate formulae to find the area of parallelograms, trapezoids, and triangles #5, 6 a, b, c, d, e - uses appropriate formulae to solve the area of regular & irregular polygons #5 a, f -uses the appropriate units when converting units of measurement #4 a, b, c -identifies and correctly applies formulae # 1. a, b, 5, 6. a, b, c, d, e, f, 9

Application -applies formulae of parallelograms, triangles, and trapezoids to solve problems #6b, 6e -finds missing dimensions of regular polygons when given the area, perimeter, and or other terms #8 -can find the area of complex shapes #5, 6

Communication -work includes formulae, units, and is show in logical order #1, 5, 6. a,b,c,d,e,f, 8, 9 -explains thinking clearly using mathematical vocabulary #7, 8 -explains how two formulae are related #7 -explanation tells whether answer is reasonable #7, 8, 9b

Below are some videos to help with clarification, answering the question WHY we use certain formulas:
