## Ellipsis Math 5

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.

In both semesters, students will be exposed to multi-step problem solving strategies (draw a diagram, working backward, making an organized list, etc.). Many problems from various math competitions will be discussed as part of our active learning as a group. Students receive weekly assignments which may take them 1 hour to 2 hours per week.

## Topics Covered

**Fall semester**

Whole numbers, Fractions, Decimals, Percent, Ratio, Rate, Speed, Angles, Geometry (Polygons, Angles, Circle, Surface Area, Volume). Within these topics, we cover applications involving factors and multiples, order of operations, multiplication and division patterns, mental math calculation, multi-steps operations with whole numbers, operation with fractions and decimals, perimeter, area, and surface area, as well as study of angles.

Sample problems:
