## Reflection: Student Grouping Twenty Twenty - Section 2: Introducing 20/20

Being that this is the first time we are playing this game and the concept of making 20 is still a challenge for a few students, I deliberately broke up the teams by ability.  This way I knew each group had at lest one person who could check for accuracy.  This also allows me to circulate to groups and spend more time checking in and seeing what strategies students are suing to solve for 20.  At the same time, it also allows me to spend time questioning students and asking guiding them through the use of unfamiliar strategies.
