Hello! This resource is perfect if you’re in need of an activity to work on adding and subtracting tens. The first set of questions focus on taking or adding one ten. There is a hundred square on the page as support. At the bottom of the page children have the chance to work on taking or adding more than one ten. They might use the working out space to draw tens and one or they could still use the hundred square. Font used is sassoon penpals. I use the acronym WATA (we are thinking about) but this could easily be changed to LO or similar.
