Problem Solving is a strategy that we all must learn. I love to let my students work together in small groups to communicate together how to solve a problem.
This set of 12 word problems (1 per page) will definitely engage your students as well as give them space to show how they worked through the steps together.
Once done, have your students present them to the class and see if others come up with other ways to solve the problems.
Correlates to CCSS: 6.NS.1,6.NS.7, 6.NS.7b; 7.NS.1, 7.NS.2, 7.NS.3
Feel free to check out how my student's used them on my blog at http://www.liveteachcreate.com/problem-solving-review/.
