These 120s chart puzzles help students practice adding and subtracting strategies using a 120 number grid. There are 26 self-grading digital task cards in this deck, each with a snippet of a 120s grid and only one number to start with. Students click on the numbers that are outside of the grid and drag them to the correct spot. Once they click “submit” green circles will appear around the correct numbers. Red circles will appear around the answers that are incorrect.
Based on plus ten, minus 10, plus one, minus one adding and subtracting. Students drag and drop the numbers to the correct spot in the grid. All numbers snap to the center when placed in the grid square. Grids vary in degree of difficulty for differentiation. Slide 1 has student directions.
