Math Detective Task Cards ! Encourage your students to think critically about problem solving by EXPLAINING and JUSTIFYING their answers on multi-step word problems. Students read a math problem as well as two detective’s ways (process) of solving the problem. Only one detective is correct, and the students have to figure out what detective did the math process correctly. Then, they have to explain why the detective is right (or why the other one was wrong). $
