I noticed several times, in both classes, that the two-digit addition with multiple addends was not accurate when calculating the player's total score. The addition was not an obvious concern in the 4th grade classroom. The activity is such a wonderful formative assessment opportunity as several students made errors in computation. The partner format lead to dynamic and productive discourse. The teacher has data to inform her instructional next steps.
