This week we will be starting Topic 7: Multiplying by 2-Digit Numbers.  Your child will be multiplying larger numbers using arrays, mental math, rounding to estimate, and also using compatible numbers to estimate.  By using estimation in the course of everyday experiences and family activities, you can help your child understand estimation. 

Help your child understand that, when shopping, he or she can use estimation to figure out how much an item will cost. For example, if T-shirts cost $12 each, have your child estimate the cost of 4 T-shirts.
