Maths Rich Task 2: The Factors and Multiples Game mr barton maths .com

Rich Tasks and Probing Questions I believe it is far more important to plan prompts and questions than worksheets and PowerPoints. Prompts and questions give you much more scope for flexible, fun lessons and allow for effective differentiation. They allow you to start everyone off on the same task, and then wander around the classroom, seeing where the students are up to, dropping little prompt cards on different students’ desks with a new line of inquiry for them to investigate. They also allow students to express themselves creatively, coming up with their own lines of inquiry to investigate. Have a play around with the following task, and then please share your ideas for extensions, simplifications, modifications, probing questions and lines of inquiry in the comment box at the bottom of the TES resources page.
