This QR code self checking activity can be used in 3rd-5th grade math as a small group activity, for early finishers, or students who need extra review. Print on card stock and laminate. Students will need to access a mobile device with a camera to scan QR codes (iPad, iPod, Smart Phone, Tablet, etc.)
This activity includes 12 number line task cards.
Students will use a dry erase marker to write the fractions that are listed in the cupcake on the correct place on the number line. Once they have written all four fractions, they will use their device to scan the codes to check their answers.
