Need a way to increase student engagement in problem solving? These self-checking problem solving posters draw students in by including QR codes. Students scan the QR code, solve the problem, and find their answer on another poster. If they don't find their answer, then they know that they have made a mistake and need to check their work. When they find their answer, then there will be a new QR code with a new problem to solve. Students may start at any point and will be lead to each problem in the set.
This set includes:
*10 problems with QR codes
*list of questions for the teacher's reference
This set of problems focuses on Common Core Standard OA3, multi-step problems involving all four operations.
