This online interactive activity from Harcourt School lets students see the process of subtraction with regrouping step by step. This website shows students a problem, and then as you press ‘next’, the sentence on the page changes and asks questions, gives directions, or explains reasons for the next step. A workmat is also provided with tens and ones blocks as well as a tens and ones chart. Showing this concept in both ways allows different kinds of learners to benefit. The illustrations and drawings really help to show each step of the way. Along with pressing ‘next’, you can also press ‘back’ if you do not understand a step or need to see it again. There is a math glossary that defines ‘ones’, ‘tens’, ‘subtract’, ‘difference’, and ‘regroup’. I think that this website really makes math accessible, because it can be utilized in so many different ways. Students can use this independently at home, or at school on the computers. It also allows teachers to provide their students with instruction in different ways, if a student is not grasping oral directions. This website could also be great for students who are Deaf or hard of hearing because they would be able to see this process at their own pace explained in two different ways that they can read visually as many times as needed.
