Even Gleeven and Odd Blodd

October 02, 2016

It's October Y'all! Is it just me or does this little ghosty crack you up? I adore him!

Last week in math we began learning about Even and Odd numbers. It was a very busy week though so we did not quite get to everything and will be finishing up this week - which is perfect because it is October and I love making our "Even Gleevens and Odd Blodds!"

In prepping for the rest of our Even & Odd unit, I thought I would share what we did last year since we are doing some of those activities again.

Back when we first learned about digits, we did learn about which were even and odd. First I had my first graders find a partner and then I told them I had different food items. If the items were even and they could share them fairly then they could eat them. This brought a great concrete idea to the concept of even & odd.

Now onto learning about how to know if a number more than 10 is even or odd.

First we played a game called prove it. The students created a game board and then passed their board to a partner and had to prove whether the numbers on the board were even or odd.

Then I let the cats out of the bag, gave each student a cat, and we sorted them between even and odd.

Once everyone finished, we all came to the carpet to look at the patterns we saw in the sorts. We made the conclusion that you have to look at the ones place to tell if a number is even or odd.
