About this course
Algebra 1 Grades 9 to 12 is a free 12-week online high-school algebra course. Students join Comet and Wren in the Loft as they build a ramp course and a bottle-rocket launcher for the neighborhood Maker Fair: units and expressions, linear equations and inequalities, functions and function notation, linear graphs and rates of change, linear models and sequences, systems of equations and inequalities, rational exponents and exponential change, polynomials, factoring, quadratic equations, quadratic functions and their graphs, and scatter plots with lines of best fit.
12-week list
Each week has short lessons Monday to Friday, a Loft Lab on Wednesday, and a Loft Day with the family on Saturday.
