Letter Sudoku Decoded With Square Roots

Pick the puzzle that matches the current unit and use it for review, an early finisher task or a warm up. Have students solve every clue before filling the grid.

Decode letters from square root clues, fill a sudoku with doubling dots and read the shaded diagonal. The directions on the page read: Evaluate each expression in the code to learn each letter's digit. Fill the grid with digits so each row, column and thick 2 by 3 box has 1 to 6 once; a letter in the grid stands for its digit. A dot between two cells means one digit is double the other. Then turn the shaded diagonal back into letters. An answer key is included.

Yes, both. We made it for 8th grade math puzzles, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.

Students solve each clue first, such as a cube root or a slope, and write the answer in its cell. Then they fill the remaining cells so each row, column and box has each digit once.

The grid usually stops working, because a wrong digit will repeat in a row, column or box. That makes each puzzle a built in check.

Clues include zero and negative exponents, square and cube roots, slope between two points, multi-step equations, scientific notation, function values, distance on a grid and systems of equations.
