This set includes 44 heavy work cards to help students or children with sensory processing difficulties. These activities can help balance a child's sensory processing modulation loop. This balance is essential for learning in the classroom. Some of these activities can be modified for the classroom. You can also send these cards home with parents to give them some ideas for their child's sensory diet which will help with learning in the classroom. For my own child, I put some magnetic tape on the back and stick them to the fridge so he can choose what he wants to do when he needs to rebalance himself.
