This was a bulletin board I did last January in Kindergarten. It is titled "Math Words." Unfortunately the picture isn't better. Included are the following words:
shapes (including play food with labels like cube, cylinder, etc)
whole, half, quarter
fewer, more (I put connecting cubes in see through bags)
top, middle, bottom
bar graph (have you ever built a snowman)
I did this bulletin board before we did addition and subtraction but they would be easy to add; maybe with Kindergarten Crayon's Blooming Addition and Heidi Butkus' Loose Teeth Subtraction. This would be a great end of year review of all the math concepts that had been learned.
