These activities are perfect for math rotations and a fun way to practice math skills learned.This is a set of 13 task cards you can place around your room for students to solve. Using the QR codes is optional but students really enjoy checking their answers with these. These cards include problems using the 100's chart, fractions, money, place value, addition and subtraction with regrouping, word problems, identifying even and odd numbers and writing the expanded form of numbers. These can also be used as an assessment. They are geared for second graders but third graders needing extra practice can use these as well.
