Here's a great Math Center activity for Adding Fractions with Unlike Denominators using QR Codes! This center activity provides practice with a mixture of 16 computation and word problem task cards for adding 2 to 3 fractions (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.
