"Students often do not see the point in solving formulas for a particular variable when there are no values given.

This activity begins by reviewing conversions between fractions and decimals with an emphasis on repeating decimals.

This activity leads students to understand the utility in the factored form of a quadratic equation. Students then express quadratic equations in standard form in the corresponding factored form.
This activity or homework assignment requires students to use a computer to access data on population, earthquakes, and sound.
Treating slope as a rate of change of two quantities with different units. There are both applications based examples and non contextual examples.
Begins with the slope-intercept equation of a line and then introduces the coordinate formula for slope before the introduction of the point-slope equation of a line.

This lesson begins with a review of the vertex formula for a quadratic and looks at two quadratics- one a vertical shift of the other- to verify that correct vertex is obtained for any quadrati

Completing the square is applied to the general quadratic to derive the quadratic formula.

This lesson introduces completing the square as a means of expanding the set of quadratic equations that may be solved beyond the extraction of roots and factoring.

The lesson begins with an exploration of the family of graphs of $$y = ax^2$$, with an emphasis on tracking the changes in the $$y$$-values for differing values of the parameter $$a$$.
