October math fun!

Math fun this week:

We discovered addition facts that equal 10. I made an egg carton to have 10 slots by tearing off two. We used 10 black cat erasers and 10 orange pumpkin erasers, to go with the October/Halloween fun theme. I told Connor that no matter how he arranged the erasers in the egg carton, it would equal 10. So, we came up with all the equations by arranging the erasers and Connor wrote them down. (Picture doesn't show all the pages we did).

We also made a Venn diagram. 

Logical thinking skills:

We made a "one difference train". Connor placed one shape on the table to begin the "train" and the next shape could ONLY have one difference. It was a little bit of a tough one. You couldn't put a shape that had two or more differences next to the previous shape. It wasn't until we made a check list with "shape, color, size" that made it easier to understand. At first Connor wanted to make a pattern, like we usually do, so this was different and required thinking skills! Here is our train!
