This download is a set of number sorts. Students will sort the numbers by whether or not they contain a certain digit. If you choose to do so, after students have sorted the numbers, they can color the targeted digit by whether it is in the ones or tens place. Thanks for looking!
These sorts address Common Core Standards 1.NBT.1 and 1.NBT.2 depending on how you use them. They would correlate well with first grade, Everyday Math, Unit 2.
