Grade 3 Math Topics

Third Grade

In the second trimester of the school year, third grade students will work on the following skills:

  • Telling time and calculating the amount of time that has passed in a situation
  • Division facts, relating them to multiplication
  • Naming fractions based on visuals, including rectangles, circles, number lines, and a set of objects
  • Finding equivalent fractions
  • Comparing fractions with the same numerator or the same denominator

You can help your child at home by having them practice these skills.  As your child begins learning the meaning of division, they are learning strategies for finding the quotient, or answer, in addition to committing the quotients to memory.  For example if a child knows that 5 x 4 = 20, they can solve 20 ÷ 4 = 5.  To show the meaning of division, students also create arrays to show the sets of groups or number of items in a group.  Students still need practice on their multiplication facts.  By the end of third grade students should know all of their multiplication facts through 9 x 9.  

For fractions, students focus heavily on using drawings and other visuals.  Students need to understand the concept of equivalent fractions having the same area by seeing them visually rather than just using multiplication to calculate an equivalent fraction.  For comparing, students learn that the fractions can not be compared unless the two whole units are the same size.  Students also focus on the unit fractions, when the numerator is 1, to make other fractions, which sets them up for 4th grade.
