The third grade is the start of multiplication, mixed fractions, and more complex number properties. As the math skills start becoming more complicated, students may need some extra help to truly grasp the concepts. Our teachers help fill the gaps in learning and offer their best tips in figuring out  

  • Students learn about angles, multiplication rules, measurements, and other third-grade math skills.
  • On-demand videos for math skills by teachers who specialize in teaching math to younger students.
  • Learn and master the fundamentals of algebra to prepare for more complex concepts in the next grade.
