Mathematics: Number Sense and Numeration

  

Dear Grade 3 Parents/Guardians:

Over the next few weeks, your child will be working with numbers from 0 to 1000.

The student will represent and describe numbers such as 894 in a variety of ways and

situations. Relationships among numbers and among digits in numbers will be

emphasized as students rename, round, compare, and order numbers, explore

number patterns, and develop number sense. Throughout this time, you and your child can practice some at-home activities such as the following:

• You and your child can play a game using two sets of number cards labelled

0 to 9. Shuffle the cards and, without looking, choose 2 cards to form a 2-digit

number. Ask your child to say the number, and to write the number in expanded

form using numbers and words. For example, 75 can be made from two cards

numbered 7 and 5. In expanded form, it is written as 70 + 5 and in expanded

form with words, it is 7 tens 5 ones. After your child has had lots of practise with

2-digit numbers, you can play the same game with 3-digit numbers, using three

sets of numbered cards.

• Say aloud various 2- and 3-digit numbers and ask your child to find the cards to

make the numbers.

• Choose a book with a large number of pages. Open the book to a random page

and ask your child to tell you the numbers 1 greater than, 1 less than, 10 greater

than, and 10 less than the page number.

Thank you for your support,

Mrs. Jeffrey
