Here students decompose numbers by placing the values as base ten models on the place value chart to help them visualize how the values carry over from value to value. students should draw all the ones, tens, and hundreds in the right place on the chart and then add it up using the visual. students may also do the standard algorithm on the side. This activity is great for students that are struggling with carrying numbers, or understanding place value relationships. This is a concrete activity that might also help struggling learners who continuously misunderstand basic computation or mental math.
