We are a member of Amazon STEM club.
We are members of the STEM (science, technology, engineering and mathematics) club at Amazon. I recommend to all my friends looking for a monthly subscription to a educational stem program to join this one. They do a great job of sending an assortment of subjects and wonderfully priced.
For our June project, we received a mathematics toy, PlayMonster Lauri Number Puzzle Boards & Pegs. My 1 almost 2 year old loved assembling the puzzles and staking he pegs. She would play with it for hours.
However, my oldest (5 year old) assembled it quickly (maybe 20 minutes) then move on. You can’t see her in the photos below but she is the reason the pegs are matching on each tile and a rainbow pattern.
