Students review grade-level math concepts on this worksheet, but instead of just writing down the answers, they have to fill the answers into a crossword-style puzzle!

All math problems are chosen according to what's appropriate for each grade level. For example, a second grade page might feature an addition problem like 47 + 10 or place value problems, like the number that represents 7 thousands, 5 hundreds, 9 tens, and 4 ones. In contrast, fourth grade pages might ask students to find the next multiple in a series, fill in the blank for a division problem like 45 ÷ ___ = 5, or round a number to the nearest thousand.

Some answers are already filled in on every page to help students get started. In addition, some problems show students how many digits are in the answer. Because answers across and down overlap, students can check their work as they go.

Math puzzles provide students with an opportunity to practice important skills. They can practice the same skill on the same page as they're learning, or they can review a range of skills ahead of a test.

Puzzles are a great way for students to practice math skills independently, but they can also be used in pairs or small groups. Students can ask their friends for help with tricky answers, or one student can complete even numbers while another student completes odd numbers. Then, they can switch answers to see if they fit.

You can vary the types of puzzle-style activities you ask students to complete. They could complete math crossword puzzles, math word finds where they find hidden equations, color-by-number where they have to find the answers to math problems before looking at the answer key, and more.
