Penny's Hidden Cubes

Penny the penguin hides part of a tower of 10 cubes, and kindergartners work out how many are behind her back. Children use a ten frame or their fingers to find the hidden part, fill in equations like 10 = 4 + ?, match an equation to its ten frame, and see the same 10 as a tower, a ten frame and fingers. Fully narrated, with a spoken hint after every wrong answer.
