This was made by request for a Primary Montessori Teacher. This 18 page file includes addition, subtraction and multiplication circles. For addition and multiplication, there is one circle for numbers 1 through 9, with numbers 1 - 9 in the second circle. Subtraction circles subtract numbers 1 - 9 from 18 - 9. There are also blanks to create your own. These can be cut out and made into booklets, or used individually. Answer sheets are provided for all circles so students can check their own work if you so choose.
