I came across these games in my collection when I was looking for things to put in "quiet boxes" for C (more about those later)
I cut out a few shapes using the colors we were working on at the time. I put the larger shapes I cut out on a piece of big paper, the smaller shapes on the cards. I wrote how many counters I wanted the children to put on the shapes. I made the two games below, but you could use any shape, colors and numbers you wish, making it age appropriate (I made this a few years ago for an older preschool classroom). For counters you could use anything - pom poms, erasers, flat marbles, beads, etc.
