Make predictions and estimations during play without much accuracy (e.g., estimate how many scoops of sand it will take to fill a small bucket at the sand table—“I think 100!”).
Make more accurate predictions and estimations during play without checking by counting (e.g., estimate how many pebbles will fill the balance scale cup, “I think 10” but without counting to check).
Make more accurate predictions and estimations during play and check them by counting (e.g., “I think it will take five scoops of sand to fill this cup– 1,2,3,4,5,6 – oh, I was almost right!”).
