What are Shikaku Puzzles?
Shikaku Puzzles are a grid-based logic puzzle that involve dividing a grid into rectangles (or squares) of various areas. These puzzles have also been known as Rectangles or Divide by Box.
The goal of a shikaku puzzle is to subdivide the grid into rectangles (and squares) so that exactly one number appears in each rectangle. Additionally, the number in each rectangle must correspond with the area of the rectangle. No rectangles may overlap.
Heart Shikaku Puzzle Instructions
Divide each heart into a series of rectangles. Each rectangle must include one of the numbers from the puzzle, and that number should match the area of the rectangle.

Puzzle Solutions
Puzzle solutions are available on a password-protected solution page. I do not openly post the puzzle answer keys because one of my goals as a resource creator is to craft learning experiences for students that are non-google-able. I want teachers to be able to use these puzzles in their classrooms without the solutions being found easily on the Internet.
Please email me at sarah@mathequalslove.net for the password to the answer key database featuring all of my printable puzzles and math worksheets. I frequently have students emailing me for the answer key, so please specify in your email what school you teach at and what subjects you teach. If you do not provide these details, I will not be able to send you the password.
Not a teacher? Go ahead and send me an email as well. Just let me know what you are using the puzzles for. I am continually in awe of how many people are using these puzzles with scouting groups, with senior adults battling dementia, or as fun activities in their workplace. Just give me enough details so I know you are not a student looking for answers to the puzzle that was assigned as their homework!
