"This was purchased for K5-2nd grade children to play with, and it should be fine for that purpose. However, the bar used to hold the number/shape blocks was too short and barely fit so that the beads could be put between each board. Without the beads the bar fit, but the boards would keep landing on the picture and never a number. With the beads the game was less sturdy, but the boards landed properly. If they are careful, it should work fine."
