Mentally add 10 or 100 to a given number 100-900, and mentally subtract 10 or 100 from a given number 100-900.

The 2.NBT.8 activities that are included in my short answer, centers, printables, and interactive notebooks are similar, but have all been changed to fit these lesson plans. The short answers have different prompts and are now part of MATH groups, the printables & interactive notebooks have been updated and are used during the ‘Apply new skills’ part of MATH groups.
