We began our new Investigations Unit this week...Number Games and Crayon Puzzles. Our focus this week was the number 10. We played various games to help us master combinations of 10. Making 10 is a fun and easy game that helps students develop fluency with two addend combinations of 10.
You need four rows of five number cards, with the numbers facing up. The goal is to find two cards that you can combine to make 10. After a combination is found both players write the equation on their white board (or piece of paper). Players take turns until no more combinations can be found.
