This is a great independent activity for math centers! I hope your students enjoy!
Included: 15 Task Cards with a number line and an equation on each.
Directions: Students use the number line to solve each equation. Students write the equation with the sum on the recording sheet. Students then scan the QR Code to self correct his/her work.
How do QR Codes work? Using a technology device (ipod, ipad, etc.) download a FREE QR Scanner from the App Store. Use the scanner to scan each code to reveal the equation with the correct sum.
I have also created these cards without QR Codes.
Any questions, please use the Q & A section.
