Adding and Subtracting Learning Goals

Here are the expectations for our new unit on addition and subtraction!

Number Sense - Addition & Subtraction

• I can solve problems involving addition and subtraction of two-digit numbers, using a variety of mental strategies
• I can add and subtract 3-digit numbers 
• I can use estimation when solving problems using addition and subtraction 

Encourage your child to go on Xtramath.org and practise their math facts or quiz them while you are in the car on numbers that you see on license plates.  Ask them to estimate how much two items at the store will cost altogether.  When planning for Christmas get togethers, ask them how many plates, or buns, or cookies, etc, you will need altogether.
