This is a fun little activity created specifically for those second and third graders working on identifying numbers and their place value/base ten representations. The pack you purchase will contain sixteen puzzles/matches with different numbers and their base ten representations on them. Simply cut apart, place in an envelope, and you have a center! If you want them to be self checking, simply put a matching sticker on each half of the cards and cut apart. My kiddoes absolutely love this one! Especially since so many of them are enamored with the creepy crawlies... Also included is a blank template in case you would like to make your own puzzles!
