This is a compilation of 6 of my math activities. All of the math centers have a winter theme to engage students while they review the math topics covered so far. The topics covered are multiplication, division, fractions, rounding, and word problems. You can buy each math center individually, or buy all 6 for just $6. These math centers were designed to meet the following 3rd Grade Common Core Standards: 3.OA.1, 3.OA.2, 3.OA.3, 3.NBT.1, and 3.NF.1. These math centers can also be used in 4th and 5th grade.
