Collecting and counting money!
Step 1: Collect all the coins in the house! (I am sure your family won't mind when you tell them it is so you can learn mathematics.)
Step 2: Sort them into groups (5c in one group, 10c in another, etc)
Step 3: Count how many in each group, then calculate the group value.
Example: You count your 5c coins, and find you have 15 of them.
15 x 5c = 75c
You can use this form:
Step 4: Add up all the group totals so you know how much money you have!
Tell everyone what a good job you did ...
... and ask if you can keep the money!
Tip: If you make stacks of coins exactly 10 high it is easier to calculate the totals.
