In Stock (Ships within 1-2 business days)
This set contains four separate “proofs” of trigonometry relations with examples of Pythagorean identity, a sum formula, a double-angle formula, and two sum-to-product formulas. Demonstration of each relation is accomplished by physically rearranging the pieces to establish equalities of areas or lengths. These are not rigorous mathematical proofs, but rather visual common-sense proofs. As such, they help make these abstract relationships real and believable. By actually handling the pieces, students engage their minds to a greater degree than they would by merely looking at the proofs on paper. The color instructions describe how each proof is demonstrated, and four reproducible worksheets reinforce the material. Contains 20 magnetic foam pieces. Grade 7 and up.
