Converting your “less than exciting” linear equation worksheet activities to puzzles is possible with a small investment in some supplies and a slightly larger investment in time. To get started, find some sturdy, colorful cardboard, a ruler, black marker, a pair of scissors, self-adhesive lamination plastic, an elastic band, and a set of solved linear equations. Dark colored card tends to be difficult to read equations from, so avoid dark colors unless you are working with white or silver metallic markers. While I prefer working with black markers, any colored pens that create contrast with the background card color will work.
Your puzzle can take any form, but simple shapes are the easiest to work with. For beginners, I recommend a square puzzle with no more than 9 pieces. Use the ruler to mark out a square on the card, and divide the square into a table with 3 equally spaced columns and 3 equally spaced rows. If you are feeling less ambitious, start with a 2×2 table. Make sure the lines and boundaries of the puzzle are drawn in bold ink. Neatly insert an equation along a side of a cell that has an adjacent cell. The solution to this equation is filled in across the boundary line in the neighboring cell. Try not to choose equations that will generate the same solution as this may cause confusion for learners who are new to this type of puzzle building. Duplicate solutions can be intentionally incorporated into more challenging puzzles, but should be avoided when first introducing these puzzles to a class or student. Complete the puzzle with equations and solutions, laminate the card for durability, and cut the puzzle into its individual pieces. Use the elastic band to keep the puzzle pieces together.
