Numbers to 100

Here are some activities for you to do at home!

1. Help your child count forward and backwards by 2s, 5s, and 10s.

2. Place 6 pennies in a row. Ask your child: "How many pennies are there?" Add a dime to the row and ask: "How much money is there altogether?" Continue using dimes to count until you reach 96 cents.

3. Line up 10 things in a row, such as spoons, forks, cups or plates. Ask your child: "What is third? Fifth? Ninth?"

4. Gather a collection of about 40 small objects for your child to count, such as toys or pennies. Ask your child to count the collection by grouping the objects in different ways.

5. Select a number between 50 and 100. Ask your child to draw a picture for the number, then show you how many groups of 10, and how many 1s.

6. Show a page number between 50 and 100 from a book. Ask: "What is the next page number? What was the number on the page that came before? How do you know?"

Unit 3: Addition and Subtraction to 18

Dear Grade 2 Families,

In this unit, your child will be developing strategies for adding and subtracting 1-digit numbers.

The Learning Goals for this unit are to:
  • Develop and use mental math strategies to add and subtract two 1-digit numbers, including zero.
  • Look for patterns in digits when adding and subtracting.
  • Understand and use the relationship between addition and subtraction; for example, 2+7=9 and 9-7=2
  • Find out if 2 sides of a number sentence are equal or not equal. 10=6+4 and 3+6 does not =10.
You can help your child achieve these goals by doing these Home Connection activities!

1. Share addition and subtraction story problems about things in your neighbourhood. For example, "There are 15 houses on our street. 9 of them have a garage. How many do not have a garage?"

2. Have your child build a set of 5 to 9 pennies and then add 1, 2, or 3 pennies to that number. Have your child tell the addition sentence. Then, take the same number of pennies away. Have your child tell the subtraction sentence.

3. With your child, look around the house for items that come in equal sets. Discuss that happens if you add items or take a few items away. Are the sets still equal?

4. When you set the table, have your child add groups of items on the table (forks, knives, glasses). Try adding them in a different order. Have your child explain why the order doesn't matter.

5. Have your child take a number if cans from the cupboard. Use a cloth to hide some of them. Have your child explain how addition can be used to find out how many are covered.

6. When you spend leisure time with your child. pose different missing parts problems. Have your child explain how he or she figured out the answer. (9 dogs are ready to compete in a dog show. 18 signed up. How many more dogs needs to come?)

7. When you solve everyday subtraction problems , ask your child questions such as, "What do we already know? " "What piece is missing?"

8. Ask your child to tell a number story using a double or near doubles.

9. Watch for situations where your child can use a strategy to add or subtract 1 digit numbers.
