New Year = New Math Fun

We are so excited to be back!  The new year brings new expectations, new learning, and new fun!  This week in math, we learned a fun game to help us become more fluent at solving missing-addend problems.  (7+___ =15)

This game can be played with 2 or 3 players.  

2 players: Player A puts a card on their forehead without looking, then places another card face up in front of them.  Player B adds both cards up and shares the total.  Then, player A uses the number in front of them and the total shared to determine the number on their forehead.  After player A solves the problem, the players switch roles. 

3 players: Player A and Player B each place a card on their forehead without looking.  Player C adds both cards up and shares the total with players A and B.  Players A and B try to be the first to figure out what number is on their forehead.  The player who figures out their card first wins the round.  Then players switch roles.  

Also, this week we learned a new math strategy called Make 10.  We teach this strategy to help us build our mental math strategies.  Click here to read an old blog post to learn more about this strategy.  

Lastly, we worked hard and independently at our math stations, putting what we learned into practice!
