Representing and Comparing Quantities

In order to make sense of mathematical ideas, students need to have a good grasp of the different ways in which numbers are used and represented. This feature offers activities designed to develop students' understanding of fractions, decimals, percentages and standard form. We hope the engaging card-matching games will offer opportunities to develop fluency, and the investigations will lead to useful insights and deeper understanding.
