For a
convenient, concrete way of showing linear equations and their key components,
ask your students to string beads.

The
algorithm for multiplying proper fractions is often taught by leading students
to notice patterns when finding part of a fractional part. An area-model
approach will extend students’ understanding.

When
students learn strategies for identifying key ideas in inductive arguments,
these ideas can be extended to provide more formal proofs.
