INSTRUCTIONS FOR USING THESE PROBLEMS:
These problems are differentiated into 3 levels. Change the numbers to suit the levels of understanding in your class. Add further levels if necessary.
For whole class whole lesson problem solving, copy problems A and B onto their own slides. Change the numbers in problems A and B on the slide with all 3 problems, to allow students to select the problem they are ready to solve independently at the end of the lesson. Students then create their own problem.
For embedded problem solving, keep all problems on the same slide, allow students to select the problem they are ready to solve.
