I created this set to help my students with number sense. Each three digit number has the number in standard form, written form, expanded form, and place value. There are 20 complete sets in this file. Copy each page onto colorful cardstock (or regular paper and laminate them) and cut the puzzle piece apart. Place them in a center and have the kids use their knowledge of numbers to put them back together again. Numbers in this set are ALL three digit numbers. I hope your students enjoy!
