Factoring Special Cases
Students explore geometric proofs for two factoring rules: a2 + 2ab + b2 = (a + b)2 and x2 – a2 = (x – a)(x + a). Given a set of shapes whose combined areas represent the left-hand expression, they manipulate them to create rectangles whose areas are equal to the right-hand expression.https://education.ti.com/en/activity/detail/factoring-special-cases_1
Sine and Cosine Identities
Students will explore the relationship between the measure of an angle and its sine and cosine. Students will develop two trigonometric identities: sinA / cosA= tanA sin2A + cos2A = 1https://education.ti.com/en/activity/detail/sine-and-cosine-identities

Have an AWEsum Fibonacci Day!
...Let a and b be the roots of the quadratic sequence x2 - x - 1 = 0. Note that a2 - a - 1 = 0 and so a2 = a + 1. Therefore a3 = a2 + a, so a3 = 2a + 1. Similarly we have b3 = 2b + 1. If we continue to express powers of a and b in terms of a and b, the Fibonacci sequence makes a surprising a...https://education.ti.com/en/bulletinboard/fibonacciday
