Need an inexpensive indoor activity???
I bought the $1.50 bag of "rainbow"colored marshmallows, then had them seperate the colors from the bag into the cups on their own! (This gave me a double-duty activity all in one.. at this age, they just LOVE sorting.)
I did a quick demo..
And my 3 year old just ran with it!
Then I tried to teach him constructing 3-dimensional.
The finished product.. "A Bridge to the Beach!" (is what he called it)
