## Ellipsis Math Pre-Algebra

Watch your child develop a love for mathematics while building important critical thinking and problem solving skills. We balance our curriculum with rigorous practices, strategy development in multi-step problems solving, and early exposure to logic problems.

The Pre-Algebra curriculum is designed to give students strong foundation to study Algebra. In-depth topic discussion and many applications are part of the in-class learning. Students receive weekly assignments which may take them 1 hour to 2 hours per week.

## Topics Covered

**Fall semester**

Properties of Arithmetic, Number Theory, Integers, Fractions and Decimals, Complex Fractions, Recurring Decimals, Order of Operations involving integers, fractions and decimals, Exponents, Scientific Notation, and geometry topics such as Pythagorean Theorem, Angles, Rigid Transformations, and in-depth study on 2D and 3D figures.

Within the topics, students will also work on applications involving percent increase/decrease, rate & speed, dimensional analysis, and distance in graphs.

Sample problems:
