# Math Games Tool: 100 Chart Games

100 Chart Ideas:

# 1. Number Patterns

Flash all numbers that have a 2 in them.
Do they form a line?
Do the lines meet?
Flash numbers that have a six in them?
What do you notice?
Flash numbers that have the same number in the ones and tens place.

# 2. Special Numbers ( use the blank hundreds chart as your child progresses)

The number of people in your family

The day you were born

The number of relatives you have

The number of pets you have

# 3. Before and After

Use a blank number chart. Have a student select a number from 0 to 100. Have your child find where the number is on the blank chart and shine their light on it. Now say the number before and after that number.

# 4. Add and Subtract Big Numbers ( use the blank hundreds chart as your child progresses)

Do more diffucult addition and subtraction beyond what your child can handle mentally.
Develop mental math skills by showing how to add or subtract the tens first (counting up or down) then the ones (counting left or right.)

#5. Patterns

Find multiplication patterns. Use your flashlight to skip count 3's, 4's, etc. (When you skip count by 3's these numbers are called multiples....good vocab. lesson).

Sing the skip counting songs at crazymathmom.com (Find the complete list in 4th grade multiplication).

# 6. To 100

Take turns flashing your light to any number. The other player has to say how many more it takes to make 100.

# 7. Fractions ( use the blank hundreds chart as your child progresses)

Use your light to show me what number is 1/2 of 100? What number is 3/4 of 100? Are you sure? How can you show it is true ( Hint: think of quarters and dollars)?

# 8. Secret Number ( use the blank hundreds chart as your child progresses)

Choose a starting number and a secret number. Use the arrows on your sky desk to help your child find the secret number. For example, shine your light on the arrow pointing right and say 4 spaces. They use their flashlight to count 4 spaces to the right. Now shine your light on the vertical arrow and go 7 spaces. This continues until the secret number is revealed!

# 9. What number am I? ( use the blank hundreds chart as your child progresses)

Have your child find a number you have secretly picked. For example, this number has a ten's digit that is more than 5 ( they then flash their light on the cottom on the hundred chart). The one's digit is less than 2. What number am I?

# 10. Money ( use with the blank hundred chart too)

Shine your light on the value of:
3 nickels
4 nickels and 4 pennies
etc.
