Third Grade Online Math Curriculum
Multiplication and division are the name of the game in third grade math. Students will be introduced to these concepts, learn their multiplication table and understand what it actually means to multiply and divide.
Having a solid understanding of 3rd grade math facts will help students grasp these important concepts and reach their learning targets. On this page, you’ll learn important information including:
What Math Should a Third Grader Know?
For third grade math, students are expected to know their fact families in addition, subtraction, multiplication and division. With this information, they will be able to solve two-step word problems and equations. In addition, third graders should know how to read and write large numbers through the hundred thousands and know the place value for each digit.
Below are a few other skills that a third grader should know.
- Add four-digit numbers
- Subtract with regrouping
- Round numbers to the nearest tens and hundreds
- Understand two- and three-dimensional shapes
- Solve word problems that involve time, money, and measurement
An effective third grade math curriculum should ensure mastery of each of these concepts/skills by providing thorough instruction and plenty of opportunities for practice. Read on to learn about our third grade math lesson plans to discover how Time4Learning’s award-winning, comprehensive curriculum can do just that.
Third Grade Math Objectives
In third grade, there are a number of math objectives that your child should achieve. Doing so will allow them to easily learn more complex concepts later. Practicing math facts in the early elementary years as often as possible will help them focus on learning these new skills and understanding more advanced concepts in the years to come.
This year’s math objectives include:
- Gain the skills to do mental math
- Multiply two-digit numbers
- Divide two-digit numbers
- Understand, compare and identify fractions
- Interpret charts and graphs
Check out how Time4MathFacts (included in your subscription) fosters strong math fact fluency through interactive and gamified lessons that keep students engaged and mastering addition, subtraction, division and multiplication.
