Learn to count upwards in English & compare counts: Click onto the Green ball and drag the Yellow clone that pops up into a bucket. The bucket speaks up, with its own voice, telling you its current ball count. Repeat with more balls to increase the count of balls in the buckets. See those counts compared on a scale.
