The 100 square challenge! Can you use your knowledge of numbers, patterns and place value to reassemble the 100 square? How about trying it against the timer? Can you even complete more than one square before the time runs out?
I printed out hundreds charts on white and BRIGHT colored paper and laminated both copies. (I have one set for every student) Then I cut the NEON paper into different shaped puzzle pieces. Students work to cover their entire puzzles quickly and quietly.
