Numbers are used to describe quantities, to count,
and to add, subtract, multiply, and divide. Understanding numbers and knowing
how to combine them to solve problems helps us in all areas of math.
Count everything! Count toys, kitchen utensils, and items of
clothing as they come out of the dryer. Help your child count by pointing to
and moving the objects as you say each number out loud. Count forwards and
backwards from different starting places. Use household items to practise
adding, subtracting, multiplying, and dividing.
Sing counting songs and read counting books. Every culture has counting
songs, such as "One, Two, Buckle My Shoe" and "Ten Little
Monkeys", which make learning to count – both forwards and backwards – fun
for children. Counting books also capture children’s imagination, by using
pictures of interesting things to count and to add.
Discover the many ways in which numbers are used
inside and outside your home. Take your child on a "number hunt" in
your home or neighbourhood. Point out how numbers are used on the television
set, the microwave, and the telephone. Spot numbers in books and newspapers.
Look for numbers on signs in your neighbourhood. Encourage your child to tell
you whenever he or she discovers a new way in which numbers are used.
Ask your child to help you solve everyday number
problems. "We
need six tomatoes to make our sauce for dinner, and we have only two. How many
more do we need to buy?" "You have two pillows in your room and your
sister has two pillows in her room. How many pillowcases do I need to
wash?" "Two guests are coming to eat dinner with us. How many plates
will we need?"
Practise "skip counting". Together, count by 2’s and 5’s.
Ask your child how far he or she can count by 10’s. Roll two dice, one to
determine a starting number and the other to determine the counting interval.
Ask your child to try counting backwards from 10, 20, or even 100.
Make up games using dice and playing cards. Try rolling dice and adding or
multiplying the numbers that come up. Add up the totals until you reach a
target number, like 100. Play the game backwards to practise subtraction.
Play "Broken Calculator". Pretend that the number 8 key on
the calculator is broken. Without it, how can you make the number 18 appear on
the screen? (Sample answers: 20 – 2, 15 + 3). Ask other questions using
different "broken" keys.
