In this unit, your child will:
- Recall basic addition and subtraction facts
- Identify and apply relationships between addition and subtraction
- Add and subtract 2-digit numbers
- Use mental math to add and subtract
- Estimate sums and differences
- Add and subtract 3-digit numbers
Here are some suggestions for activities you can engage in with your child:
- Play Store with your child. Price some of the items in your home in cents (for example, the cup of noodles costs 149 cents and the baguette costs 35 cents). You are the Shopper and your child is the Cashier. Have your child add the cost of the items you buy.
- Roll a die 4 times. Use the numbers rolled to make two 2-digit numbers. Have your child subtract the lesser number from the greater number. Repeat the activity. This time, roll the number cube 6 times and make two 3-digit numbers.
