Pom pom sorting is a BIG hit in our class
I found a four sectioned tray at The Goodwill. I then cut red, yellow, green, and blue paper to fit in the bottom of the tray. The students then sort the triangle shapes by color. An extention to this work is to have a triangle shape on paper squares with a blank line and small circle. Have the students color the triangle yellow and then write yellow on the line and write the number of yellow triangles. Repeat with red, green and blue. Have a control card with the color word on it so they can check how to spell it.
This is a variation from Miss Patty's Montessori Day
