# Representing 10

September 6, 2017

Today’s intro challenge was to show 10 in as many ways as possible, and there were some impressively creative methods shown!

We can count out 10 things individually, or put them in an array, like the business cards.

Here’s a different array, a 2 by 5 array.

Some used money, showing adding and subtracting.

Some used dice to show how to make 10.

And of course, everyone’s go-to manipulative for “10” is hands!

We also even had a push up representation!

We used our skill to decompose numbers and add and subtract, and also to help us when we multiply big numbers using the area model.
