Here's a great Math Center activity for Finding the Least Common Denominator using QR Codes! This center activity provides practice with a mixture of 12 computation task cards. This is a great warm-up/supplement prior to completing the task card sets I have for Adding and Subtracting Fractions with Unlike Denominators!! 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.
