This is a powerpoint that walks students through the steps of using the four operations with fractions (adding, subtracting, multiplying, dividing)
It also contains slides that allow for formative assessment in which the students try to solve a problem by themselves. If each student had a small whiteboard and marker they could hold up their answers to show the teacher.
It would be useful to print this powerpoint out for students to make notes on and fill-in while the teacher projects it on the board.
This would be a great resource to introduce the lesson with and then move on to a worksheet for independent practice or a fraction game involving cards or dominos with partners.
