Looking for some Common Core-aligned word problems for second grade? Looking for some great QR code fun?!?! Great! Here you go! Included are twenty-four addition and subtraction word problems, an answer document and answer key. All questions have a QR code in the bottom left corner so students can check their own work - great as a center activity!
I've created the questions on individual slides in case you would like to do these whole group on a Smart/Promethean board. Another option is to print the PDF four to a page for centers. This is what I did for my second grade teachers so they could use them in rotations.
