Look: On this night we made ramps for our cars and balls (and whatever else my two wanted to try and roll) in our playroom. The pics just show one type but we made a few and the kids spent a good portion of the evening rolling things on ramps. It was simple to make ramps we used painters tape and an odd shaped box that we had cut up.
Learn: They may not get the idea of what rolls and what slides but we will revisit this one when they will. What they enjoyed most was putting another car or object at the bottom of the ramp, then letting something smash into it. It completely delighted G and he would shout "boom" every time.
Love: We had fun doing this, but I love the pic I got where G is really studying what he was doing!
