$ bin at Target has some great treasures! I found these great little square, cylinder and triange foam blocks and created these boards with cereal box cardboard and construction paper. The friends at You're Invited worked with these materials for the whole morning :)
There are so many skills these friends are working on!
Patterns, eye-hand coordination, sequencing, estimating, color matching, counting, seriation, cooperation...
Can you list more skills this super low cost but great activity provides?
