Equation Unknown Puzzles
Puzzle Workbooks for Kids - Updated Each Month!

Equation Unknowns puzzles are another great way to teach critical thinking skills while also drilling math skills. Given values are represented by shapes, from which students solve equations and deduce the values. Again, there are multiple puzzle types, and you can choose from various customization options. At their easiest levels, Equation Unknowns puzzles involve addition or subtraction and only two shapes, but as the puzzles increase in difficulty, they can include three and four shapes, a mix of operations, and negative numbers. If your students just can't get enough, you can even print one page of each puzzle, resulting in thirty-eight pages of puzzles!
