Grade 1 Math

How many are hiding? How many are missing? How many more do I need to make the number __? These are a few of the questions we answered today while in Math. We are working on subtraction strategies so today we took turns "hiding" dominoes from our partner, and then telling how many were missing.  We had to tell how we knew what was hidden ~ "I know you covered up 3 because there used to be 5, and now there is only 2, and 3 and 2 make 5." Feel free to work on this strategy by playing the same type of game at home ~ increase the numbers as your child becomes more confident in the strategy.
