Challanges

1. Conduct estimations to let the kids guess the number of pebbles present in your hand without looking into it. Generally, the kids have to guess it by listening to the sound it makes.
2. Use sequence and series with pebbles to let kids guess what comes after a certain number of pebbles (odd, even, prime, multiples number). For example, after 2, 4, 6 pebbles, what number of pebbles will come next?
