Understanding how our ten number system works enables students to see interesting and useful patterns and relationships in these math activities. These patterns allow students to develop more efficient mental math strategies when multiplying by multiples of 10 or 100. Students will also review rounding and apply this skill to larger numbers - up to 100,000’s place.

Multiplication is essentially repeated addition, or growing numbers by doubling, tripling, quadrupling, and so on. This unit presents mental models and strategies that help students learn and review the concept of multiplication. Students explore multiplication using arrays, partial products, doubling methods and the standard algorithm to solve numerical and word problems. Students will multiply whole numbers and simple decimals by base ten exponents (i.e. .3 x 103).

If you think about math as a language, expressions and equations are the sentences. This unit brings students into the world of “math language”, learning how to write complex expressions in different forms and convert numbers in one form to another (i.e.decimals to fractions). Last, students will apply the order of operations to interpret and solve simple algebraic equations.

Multiplication facts can be tricky for students, but giving them plenty of practice can familiarize them with these numbers. From tables to questions to interactive games, there are many different ways that students can practice fact families. In this guided lesson, students will practice one-digit multiplication facts, preparing them for higher-level math skills later on. When they're comfortable with these facts, other math problems will become a breeze. Practice now!

Learning how to represent numerical information is a key part of the third grade math curriculum. This lesson in data provides guided instruction designed by our team of curriculum experts and teachers to present this concept in an engaging way. Not only that, but helpful exercises help kids to see the practical applicaton of these skills in the real world.

Teaching kids additional subtraction strategies is one way to boost math fluency and comprehension. This guided lesson, designed by our team of curriculum experts, teaches various strategies to find the difference, and provides exercises that help kids to practice these strategies on their own. For more opportunities to practice, try downloading and printing the third grade subtraction worksheets recommended by our curriculum team.

This guided lesson takes kids on an exploration of the world of measurement, from weight to volume to recording data. Commonly, third graders have a difficult time applying math skills to real-world problems, but this lesson, designed by our curriculum experts, will help provide important context for measurement skills. For even more printable practice, consider downloading and printing the recommended measurement worksheets.

Fractions can be a tricky concept for third graders to master, but this guided lesson can help kids get there. It provides focused instruction designed by teachers and curriculum experts that is specific to the third grade curriculum. Exercises and practical examples help kids to put fractions in context with real-world math problems. When finished with the lesson, check out our fractions worksheets for more practice.

Representing data on graphs makes math visual and involves some creativity and design. Plotting data using fractional units takes their learning one step further. Also in this unit, students learn to measure using both traditional units (like inches, feet and yards) and metric units, and how to convert measurements within each system. The concept of measurement gets two dimensional when students explore measuring and working with angles.
