Here's a great Math Center activity for Subtracting Fractions with Unlike Denominators using QR Codes! This center activity provides practice with a mixture of 16 computation and word problem task cards (great for rigorous Common Core practice). Students will have to explain their mathematical thinking with these problems! Students can check their work by scanning the QR Code. *Please make sure that you have a QR Code Reader app downloaded to your mobile phone or tablet device for your students.
