Activity: Number of The Day
Materials
Paper
and pencil
(optional)
Before you begin:
Choose
a number that you will call the “number of the day.” The first time you do
this
activity, choose a number under 15.
1. Find one way to make the number of the day
Ask
your children to think up different ways to make the number of the day,
using
equations.
“Let’s
all try to come up with different ways to make 11.
Here’s
one way: 8 + 2 + 1 = 11.Can you find a different way?”
2. Collect everyone’s equations
If
your children know how to write equations,
they list their ideas and take turns reading them.
When
you’re in the car, or if younger children need help, appoint one person “record
keeper.” As people give their ideas,
the record keeper writes them down
in equation form. When
everyone’s hands are busy making dinner, folding laundry, or pulling weeds, just
take turns telling each other how you
made the number—no writing is
needed.
3. Find more ways to make the number
See
how many different ways everyone can find to make the number of the day.
You
can offer specific challenges to give
children practice with something
they’re doing in school, or just for variety.
For ages 5–7, try using …
Addition with three numbers
1
+ 3 + 7 = 11
Subtraction
13
- 2 = 11
Addition and subtraction
6
+ 6 - 1 = 11
Coin values
2
nickels and 1 penny is 11 cents
For ages 7–9, try using …
Pairs of the same number
2
+ 2 + 3 + 3 + 1 = 11
Multiples of 5 and 10
25
+ 15 - 30 + 1 = 11
The number 100
100
- (3 x 25) - 14 = 11
“The
number of the day was 6. Sarita
made 1 + 2 + 3. Dad’s
was 20 – 15 + 1,and Grandma said 4 x25
– 80 – 14. She had to
explain that one!”
You
can use this activity to give your children lots of computation practice. Try it just about anywhere—on the bus,
in the kitchen, or even while folding laundry.
