Update: Now 56 task cards
To use these task cards, you can purchase the small red cups for a dollar at some locations and the craft sticks as well. You can make a STEM bin the students would use in the mornings, during your Science time, exploration, centers, inside recess, you name it.
In the beginning, I would let the students explore building with these materials before you introduce the cards.
Note: The price will increase as I add more cards.
