Can you reach level X?
393 pages, more than 4000 questions across several levels of increasing difficulty.
Students can challenge themselves in addition, subtraction and multiplication.
Each book begins with single digit math, which then increase in difficulty in each level until they are challenging themselves with very large numbers.
Either let children work through the book themselves over time, or lay out the levels on the floor in order and ask children to choose their own level.
My students loved trying to get to ‘level X’.
