I almost always start the year off with a roll and cover game. They are pretty easy for kindergartners to learn how to play and they can be differentiated pretty easily.
The beginnign of kindergarten I like to focus on Pete the Cat and Jennifer Knopf from Herding Kats in Kindergarten has a roll and cover that I use. You can check it out here. I also like roll and color which is the same concept just you color the picture instead of cover it. I have one of these in my newest math pack Sweet Treats.
I try to include some kind of dice game in any unit I create for math. Another one that has dice games is Growing A Garden of Math Activities. There is a bump game in this unit for spring or a plant theme.
Last year in first grade, I bought Just Add Dice Math Games Bundle from Jennifer at First Grade Blue Skies. I loved this bundle. I could find a game for any first grade skill I was looking for and there was a theme for anything. This became one of my favorite resources to use through out the year.
My friend Kristen and Kristen's Kindergarten had a post all about dice games as well. So be sure to check her post out.
Hopefully I'll be back again next Monday to talk about some more Math games that I use. But meanwhile check out the party at Kinder Kraziness and see what others are doing in math.
