Free Printable Four Fours Puzzle worksheets

Start with a simple target number, like 1 or 2. Model one or two solutions on the board, such as (4+4)/(4+4) = 1. Emphasize that the goal is to use exactly four 4s and any operations they know. Encourage collaboration and sharing different solutions to show there's often more than one right answer.

These puzzles are excellent for reinforcing the order of operations (PEMDAS/BODMAS). They also build number sense, strengthen arithmetic fluency with all four basic operations, and encourage creative problem-solving as students experiment with different combinations of numbers and symbols.

A frequent error is neglecting the order of operations, especially when parentheses are needed to group numbers. Students might also struggle to think beyond basic operations or forget the constraint of using exactly four 4s. These struggles can highlight gaps in their understanding of how grouping symbols affect an expression's value.

Wayground's Four Fours worksheets can be assigned as a digital activity on the platform or printed as a PDF for hands-on practice. Every worksheet includes a complete answer key. For printed work, you can use the Wayground for Teachers app to quickly scan and grade student submissions.

For students needing support, start with smaller target numbers (1-10) and allow the use of a "cheat sheet" of pre-solved examples. For advanced learners, challenge them to find multiple solutions for each number or introduce more complex operations like square roots (√4 = 2) and factorials (4! = 24).

This puzzle directly supports the Common Core Standards for Mathematical Practice, particularly "Make sense of problems and persevere in solving them" (MP1) and "Attend to precision" (MP6). It requires students to apply their knowledge of arithmetic and properties of operations to a non-routine problem, moving beyond simple calculation to strategic thinking.
