Students explore the basic shape of the parent parabola y=x^2. They identify how the graph changes in appearance and location when a constant or coefficient is introduced into the parent equation. Students conclude with an introduction to the quadratic formula and its uses in finding the zeros of a function. Full Review »

Students form a pattern called a geometric sequence by dropping a golf ball from successive heights. They explore the constant factor of this sequence, referred to as the constant or common ratio. Finally, students develop a plan for data collection and analysis to demonstrate that the stated hypothesis is valid. Full Review »
