Algebra 1.5 is a spiral review class covering Algebra 1 topics. Prealgebra topics may also appear, especially as a step in a longer process. Topics may also include looks ahead to Algebra 2 and beyond. Since this is a spiral review class, Algebra 1.5 modules do not need to be taken in any order.

This module covers these topics:
Multiplying polynomials
Linear equation writing
Geometry applications (rectangles and triangles)
Arithmetic and geometric sequences

Each topic will go through this cycle:
Learners will receive a preparation assignment and try it on their own.
After trying preparation assignments, learners can choose to watch tutorial videos on the topics of the assignment.
Learners can post their strategies and any further questions they have.
Some topics will also have an extension assignment, which learners can choose to do. Learners can also suggest their own extensions and ask questions about them.

Questions from enrolled learners will generally be answered within two school/business days. Questions from subscription learners will be answered as time permits.

Learners' questions and posted strategies, in anonymized form, may be worked back in to lesson content for the benefit of further learners.

This class is suitable for learners who have completed, or are close to completing, an Algebra 1 course or equivalent material. It is not intended for learners who have already studied a significant amount of Algebra 2. This class may be particularly relevant for learners who are in the Geometry year of a "sandwich system" curriculum (i.e. studying Algebra 1, then Geometry, followed by Algebra 2), those who are reviewing Algebra 1 over the summer, or those who have mostly completed an Algebra 1 curriculum and are starting to review mixed material. Learners who are most of the way through the first of three years of a high school integrated math curriculum, or further, are also on-level for this course.
