The children pretended they were math detectives and used ten frames showing numbers from 1 to 10 as their clues. Their task was to figure out the fastest way to move from one number to the next. They were given a number card and asked to show this number on their blank ten frame.
Then, they were given a different number card and asked to show this new number on their ten frame. The key was not to completely clear their frame, but to add dots (to move from 6 to 10, for example,) or subtract dots (to move from 8 to 3, for example).
At home: Create your own ten frame by dividing a piece of paper into ten boxes. You can use circles cut out of construction paper as your counters, or any set of ten objects (e.g. beads, beans, cotton balls)
