3rd grade is where math shifts from adding and subtracting to multiplication, division and fractions. Our program builds each idea with visuals, arrays and real-world examples.
Key Topics Covered:
Rounding, multiplication and division within 100, fractions on number lines, time and measurement, area and perimeter, shapes and scaled graphs.
Parent Tip:
Grade 3 is the first year of state testing. Our lessons build the reasoning those tests assess, without the stress of test prep.
