Gameplay: Shuffle the number cards and put in a face down pile. On each turn, put the top three cards face
up. Each player can cover up any number which is the sum of any two of the revealed cards. For example, 3,
4 and 9 would mean you can cover 7, 12 and 13. Since each child has a different gameboard, this prevents
just copying the spaces covered.
Questions: Which cards do you need turned up to cover ___ or to finish a row? If a 4 is turned up, what
other numbers would you like to see turn up?
