We've been spending a lot of time this week working with snap cubes to help us think about different ways of making ten. A game we like to play is 'Hide 10'. Mrs. McLennan holds up 10 cubes. She then hides some behind her back. Children look at the remaining cubes and guess how many are hiding. Recognizing the number of cubes builds subitizing skills and thinking about how many might be hiding reinforces mental math and addition abilities.
We wanted to encourage children to record these ideas on paper so that they could further their understanding and think about how these math ideas looked in an equation.
