The worksheet titled "Runaway Math Crossword Puzzles: Math Facts, Mental Math, Running Addition, and More" features puzzles that look like a crossword, but instead of having students find the correct words to fill in the boxes, they have to find the correct equations to fill in the boxes.

Operations include addition, subtraction, multiplication, and division, depending on what's appropriate for each grade level. The directions at the top of the page are accompanied by a series of numbers and operation symbols that function like a word bank. Each time students fill one into a square, they can cross it off, helping them to complete the puzzle.

Problems get more difficult with each grade level. In addition to introducing multiplication and division, some sections of the puzzle feature running addition problems where students add multiple numbers together to get the answer. Some feature equations that equal other equations, like 6 + 3 = 4 + 5.

Practicing math facts in different ways can ensure those facts stick with your students. In addition to giving worksheets with standard math fact problems or giving timed tests, try adding some puzzles to your students' routine.

Math crosswords can be a great way for students to practice facts that are relevant to their learning level. They fill in the boxes with equations, using the numbers and symbols at the top of the page to figure out what is missing. You can also encourage critical thinking and problem solving if you include running addition problems as well as equations that equal other equations, like 8 - 6 = 4 - 2.

Keep things interesting by providing your students with other types of puzzles, too. Math word finds can help students practice their facts, as can Sudoku-style puzzles and even color-by-number activities.
