Adding, subtracting and rounding with decimals will enable them to apply the strategies in new ways and enhance their understanding of the base-ten number system.

This year, third graders will build a stronger understanding of division. This guided lesson uses the repeated subtraction strategy as a way of teaching division. The lesson shows how division problems can be solved by repeatedly subtracting the same number (the divisor). Not only does this help students solve division problems, but it also builds a conceptual understanding of division. For more practice, check out the suggested division worksheets.
