Comparison Grid With Irrational Clues

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.

Mark roots like the root of 7 and 13 on a number line, then use them as clues in a 5 by 5 grid. The directions on the page read: Estimate each square root and mark it on the number line. Then fill the grid so each row and column has the digits 1 to 5 once. A sign between two cells opens toward the greater digit. A circled root between two cells has a value between those two digits. A root in a cell is that cell's digit. 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.
