First, I played "What's Moving" with Ready to Go. I got the idea for this at Chasing Cheerios.
I was surprised at how much she enjoyed playing this game and remembered it the next day! It's very simple- just tie a string around an object and hide it under the blanket and then slowly pull it out. She loved peaking under the blanket to see the object.
The next activity helps develop hand coordination, concentration and exploration. I had a jar of old unused beans so I let Eager to Help and Ready to Go have at them. They sat on a mat (for easy clean-up) and I gave them two small bowls with various spoons to carry the beans from the jar to their cups. They requested a large bowl to make soup in. Eager to Help was calling out measurements! They enjoyed this for at least 30 min. and then we used a fun slotted spoon to pick up the extra beans off the mat.
