Grade 3 Math
Grade 3 math introduces multiplication and division, builds fraction foundations, and develops measurement skills with area and perimeter. Students move from additive to multiplicative thinking.
What You'll Learn
- Multiply and divide within 100 using equal groups and arrays
- Understand fractions as numbers on the number line
- Compare fractions with the same numerator or denominator
- Measure area by counting unit squares
- Calculate perimeter of polygons
- Tell and write time to the nearest minute
- Identify and describe patterns
- Round whole numbers to the nearest 10 or 100
