This Domain: Operations and Algebraic Thinking lesson plan also includes:
Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another game, scholars examine clear bags with small items to determine how many more would be needed to make 10. They can use missing addend sentences and search for other groups whose bag has the needed amount to combine! A word problem is also included.
