Resources for this term:

Students use algebra and graphs to explore how the standard, factored, and completed square forms of a quadratic relate to the intercept, roots, maxima, and minima of function.

Students solve the problem of how many different tiles are needed to create a pattern at various sizes and explore alternative algebraic and geometrical approaches using linear and quadratic relationships.

Students identify parallel and perpendicular lines and find points of intersection and x- and y-intercepts by looking at the equations of the lines.

Students connect descriptions of everyday situations with distance-time tables and graphs and relate speeds to the slopes of the graphs.
