3rd Grade Math Curriculum
In third grade, students now have a good grasp on basic math concepts such as addition, subtraction, and basic shapes. This year, students will learn about multiplication, beginning to memorize multiplication tables and even simple division rules. Students will also expand on their knowledge of measurement and geometry to calculate perimeter and area.
Our 3rd grade math curriculum uses life-based learning — and we’re not just talking about word problems! In each lesson, students will follow Justin and Mia through situations like a community market, a family barbecue, and the park to learn about real-world math applications.

Course Information
3rd Grade Math Curriculum (Math Level D)
3rd grade math lessons begin to tackle more multiplication and division, advanced word problems, four-digit addition, and three-digit subtraction. Students will explore fractions in greater depth, learning to find equivalents, as well as add and subtract fractions. The curriculum also introduces rounding, advanced measuring, and perimeter calculating. By presenting these concepts in real-world scenarios, our curriculum boosts confidence in everyday practical math applications.
