This is a great alternative to using worksheets while providing students with extra practice comparing fractions with different denominators. QR codes are optional but a fun and interactive way to practice. There are 20 task cards , a student answer sheet and an answer key should you decide not to use the QR codes. Just print and laminate for durability and they are ready to go. These are great in your math centers or can even be distributed around the room so students can do a few a day during their math rotations.
