Prealgebra

Academic Year Mathematics

We start Prealgebra by formalizing the rules of arithmetic that students learned in elementary school, so they can build on a rigorous foundation as they move into algebra. We then survey a wide range of topics, including number theory, algebra, geometry, counting, statistics, and probability. We introduce each topic with compelling problems, many of which are drawn from major national math contests such as MATHCOUNTS and the AMC 8. We place special emphasis on challenging word problems throughout the course.

Students completing Prealgebra are ready to move on to a more in-depth study of algebra and discrete math in our Algebra 1 course.

Textbook: Prealgebra by Art of Problem Solving.

Hardcopy and temporary access to the online version of the textbook are included in the tuition and fees of this course.

Sample Problems

Below are examples of some of the types of problems that students will encounter in our Prealgebra course.
"Our homeschooled son is extremely gifted in math and science.  He really feels at home at AoPS Academy.  Through coaching and personal attention at AoPS, he achieved a 5 in AP Calculus at 11 years old and a 4 in AP Statistics at 12.  He also achieved an 800 on SAT II math at 12 years old.  Our son feels very comfortable in the atmosphere of AoPS, where being gifted in math is not looked down on, but treated with respect.  He has truly found his peers at AoPS Academy. 

AoPS Academy allows my son to be himself, learn that there are other kids well advanced in math, and gives him the confidence to know that it is OK to be great in math, and that other people will respect and value his ability."
