This is a jigsaw puzzle detailing questions and answers about the human digestive system.
This is a wonderful review activity (especially for middle school kids) that my kids found very enjoyable, and I'm confident yours will also.
The cell has 48 pieces and when finished, covers an area of about 40in x 30in (3.3ft x 2.5ft), and really brightens up a classroom as an informative wall poster when finished.
If wall space (or lack thereof) is an issue in your classroom, the puzzle is also included in a word document, with each piece being easily moveable with the computer mouse to click perfectly into shape. It may also be printed and used by the students as individual puzzles to solve.
Please see screenshot to understand what I have described above. For any questions, please don't hesitate to contact me.
