There are 20 problems - 1 per page. Students are asked to translate verbal expressions in to Algebraic expressions (some require them to also solve after they have translated). When they are finished they can check their answers by scanning the QR code using their phone or tablet! If the problem says to "translate and solve" both answers will appear when they scan the code.
This was intended for 6th grade students, so the problems students are asked to solve are all one-step equations. All problems involve positive integers only. There are 6 challenge problems and a few problems with inequality symbols -- my students were asked to translate these problems but not solve them.
