Cross Sum Puzzles

All NEW! These challenging new puzzles are a great way to get working on both logic skills and math skills! Fill in the blanks with digits 1 to 9 while making sure that all the sums are correct. It's not always easy!

We are producing these puzzles in packs of 12, so that you can really get stuck in if you enjoy them. Each set comes in 3 formats: 1 large per page printable, 4 small puzzles per page printable, and a 1 puzzle per page display pack designed to go up on your white board or computer screen. The display pack has a puzzle followed by the solution, so you can hand out the printables and then check them on the board together. We also include a set of printable solutions.

We are starting with simple addition and subtraction cross sum puzzles. Multiplication, fractions, negative numbers and mixed packs are coming soon.
