Today, we worked on how to break apart a number to solve a subtraction problem. Gracyn completed problems using 10 frames, first subtracting to get a ten and then subtracting the remaining amount. This concept is challenging but allows for the ability to more easily solve subtraction problems using mental math. Gracyn then watched a video on BrainPop Jr. about adding and subtracting 10's. She completed an online word problem quiz that correlated with the video. Finally, Gracyn used her white board to solve subtraction by 10 problems using numbers up to 100.
