5th Grade Mathematics

Academic Year Mathematics

Students complete their study of the arithmetic of fractions, decimals, and negative integers. They are also introduced to topics in geometry, number theory, statistics, and beginning algebra through lessons on three-dimensional solids, factors and multiples, statistics and data, sequences, and ratios. As with our earlier elementary school classes, we include challenging word problems and puzzles to teach students mathematical modeling and deductive reasoning.

After completing Grade 5 Mathematics, students are ready to start building a solid foundation for algebra in Prealgebra.

Sample Problems

Below are examples of some of the types of problems that students will encounter in our 5th Grade Mathematics 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."
