## Reflection: Advanced Students Cover Up - Section 3: Station Time

For those students who can fluently add a one digit number to a two digit number, I ask them to play the Subtracting From 120 game.  This game is similar to the Adding It Up game.  However, these students are starting at the number 120 and subtracting the number rolled each time.  These students are fluent enough where they will not need to use 120 counters to start (CCSS.MATH.CONTENT.2.NBT.B.5).

Here is the recording sheet: Subtracting From 120.
