Math game: Estimation and grouping


This is a good math game to introduce the kids about estimation and grouping.

Estimation:
I get 4 jars and put different kinds of items inside. The boys have to look through the jars and guess or estimate how many of those things. I wrote their answer down on a piece of paper.

After everyone had done their estimation, I took those items out and counted with them one by one. We then compared the answer which they gave earlier and see who got the most answer right.

Grouping:
After we took all the items out, I asked them how they can group those items into different categories. For example the toy soldiers and Indians, they grouped them into different categories. They noticed that there are different colors, some soldiers standing and some bending and they group them into soldiers and Indians.
