One of the best ways to teach students about benchmarks with fractions is using a number line. Once students master the placements of these fractions, they can start working on adding fractions, subtracting and eventually can use multiplication and division with these. This hits areas with learners that are helpful.

Place Value chart love this. I want to make a layout and laminate it. Then it can be used over and over again. Also you could attach baggies and the students could add the model blocks instead of drawing them. Can't wait this will be perfect for my second graders :)
