Tarsia Puzzles are a great higher order thinking activity to give the students. It will help to reinforce concepts and can be used as a review or informal assessment. I created this Tarsia Puzzle to review scientific notation that my 8th graders recently learned. I made it competitive and gave rewards to each pairs/groups that completed the puzzle.
When printing, make sure you choose the "Fit" print option rather than "Actual Size" so it fits to the page.
