Find the Total Area of Two Rectangles (3.MD.C.7) is a timed, interactive math game where students solve area problems by building and analyzing rectangles like a “garden plan.” Players work with adjacent rectangles and L-shaped figures, using the distributive property and missing side length reasoning to find the area of each part and the total area.

On each new challenge, the screen displays a grid-based diagram—often an L-shape—and students can draw directly on the board using a built-in pen and eraser to sketch a cut line that splits the shape into two rectangles. Then they enter:

  • the area of Rectangle A
  • the area of Rectangle B
  • the total area
  • and, in certain rounds, a hidden side length

The game provides immediate feedback, celebrates correct answers with encouraging messages, and tracks progress with a streak counter, total correct answers, attempts, and a high score. A 5-minute timer adds excitement and focus, making it perfect for math centers, fast-paced review, or whole-class practice. Teacher can use this game to build images that they can download as a PNG, making it easy to save examples they can use on a worksheet.
