Exponent Clue Sudoku, 4 by 4

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.

Evaluate zero and negative exponent clues, then fill a 4 by 4 sudoku with the digits 1 to 4. A zero exponent makes any nonzero base equal 1, and a negative exponent means the reciprocal: 5 −2 = 1 5 2. The directions on the page read: Find the value of each expression and write it on the line in its cell. Then fill the empty cells so each row, column and 2 by 2 box has the digits 1 to 4 once. 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.
