### Mathematics: Number Sense and Numeration

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.
