This activity kept my son and his friend entertained for at least 45min (which is a long time for him) the other day. You won't believe what it is...... RICE BUBBLES!
I picked up a cheap homebrand bag of rice bubbles, poured it into a large container, provided spray bottles, scoops, shovels, cups, boxes, trucks and they had a blast. Spray bottles are good for hand strengthening and eye-hand coordination, scooping and pouring great for eye-hand coordination development too, pushing trucks around great for building up shoulder stability and body awareness, AND the rice bubbles crackle with the water and are a great sensory experience!
Don't you love it when such an easy play activity is sooo great for their development and is fun!!!
