Welcome!!! At the top, click the "classroom" tab? Go into Roblox Math and on the left side there are all the levels. These are the workbook pages one by one. You have access to all 5 levels with 16 challenges in each level. Feel free to do as many as you'd like. The kids earn 800 robux for every 8 they complete so they're usually pretty motivated to get started. I recommend doing at least 1 per week, if not more.
