## Unit 1

In this unit look at numbers up to 10 000. We will be rounding numbers to the nearest ten, hundred and thousand.

Typical problems for Grade 4 will include examples such as

"Use the digits 1, 9, 5, 4 to create the greatest number and least number possible and explain how you know your answers are correct."

"How high would a stack of 10 000 pennies be?"

"I have three bills and 6 coins. How much money might I have?"

"How far would 10 000 steps take us?"

Take the opportunity to practice these problems, and problems similar to these with your child at home. As much as possible, try to embed your math practice into your daily activities with your child.

## Unit 4

We are now back to Number Sense and Numeration. In this unit, we will be adding and subtracting 4-digit numbers. We will also explore strategies to mentally add 2-digit numbers. We are beginning to introduce multiplication. In Grade 3 we learned to multiply numbers up to 7x7 and now our focus will be multiplying up to 10x10. Students should be working on developing quick recall of these multiplication facts, however the best way to do this is not through memorization, but through strategies, such as "If I can count by 5s, I know the 5x table." "If I know the 5x table all I have to do is add one more group and I also know the 6x table." (i.e., to think about 6x4, I know that 5x4 is 20, so one more group of 4 is 24). By using these strategies, students will be able to understand the concept of multiplication and, with more use, the recall of facts will become automatic.
