A great Common Core independent self-checking math center for place value! Students clip a clothespin to indicate the value of the highlighted number. It's differentiated to meet the needs of below average through above average learners. The places range from the ones through the hundred thousands. The Common Core standards addressed are included in the packet to make planning a breeze. Students only need the cards and clothespins which make setting this center up easy-peasy! My students enjoyed it; I hope yours will, too.
