This is a Follower Favorite Freebie that can be used anytime of the year! This was created in 2017 and originally shared on my blog, Smitten with First ( here). This is great to use when teaching place value, picture form, expanded form, 10 more, 10 less, 1 more, 1 less. Simply pair your students up in table groups or with a partner and have them write/draw their number in the various forms that are on the posters. Students stick their sticky notes to the correct posters. This is so much fun
