Order up a resource on comparing rational numbers. Scholars order fractions, decimals, and percents by converting to a single form. They conduct a cut-and-paste activity ordering three sets of rational numbers.

The 15th lesson in the series of 24 helps your classes understand the ppm (part per million) unit of measure. First, scholars experiment with food coloring to determine concentrations before applying their findings to calculate...

This unit on fractions allows for upper-aged elementary learners to explore ways to find the greatest common factor and least common multiple of two numbers. Ultimately, young mathematicians will be able to identify equivalent fractions,...

Ready to add some innovation to your significant figures lesson? Pupils practice sig fig rules using a puzzle approach. Check out the Teacher's Area for printable materials, an answer key, and strategies for implementing the resource.

Add an outstanding resource to your repertoire. The first installment of a 36-part module looks at the relationship between addition and subtraction through an activity using tape diagrams. Pupils develop the identities w – x + x =...
