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.

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).

Geometry in third grade introduces kids to the idea that shapes have different categories (rectangles, rhombuses, etc..) attributes (four-sided, etc...) and areas of different values. This lesson, designed by our curriculum experts, provides the guided instruction and practice that third graders need to conceptualize shapes in a deeper way. For more practice, download and print the third grade geometry worksheets recommended as part of this lesson.

In this lesson, kids are given different strategies for finding the sum of two numbers. Addition strategies such as these help third graders gain a deeper understanding of, and fluency with, this operation. The lesson features guided instruction and plenty of practice problems to apply what is being learned. For even more practice, try our third grade addition worksheets recommended to accompany this lesson.

Students will have a basic understanding of fractions coming into 4th grade. In this unit students will get to explore new ways of representing fractions, including in a set of data, on number lines and using area models. Students will use their knowledge of fractions to compare fractions with like and unlike denominators.

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.

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.

In this 5th grade division unit, students will take their understanding to the next level by applying division skills with multi-digit numbers. Students will also begin to explore division with decimals and practice using estimation to check the reasonableness of their answers. Last, students will use their knowledge of the base ten number system to divide decimals by base ten exponents (i.e. .4 ➗ 104).

Calculating the volume of rectangular prisms is a new skill that is introduced in 5th grade. Students will apply mathematical formulas to find the volume of different kinds of figures and also determine the volume of a figure composed of two connected rectangular prisms. Learners will also work with other kinds of measurement when they make larger or smaller versions of figures (to scale) and learn to convert measurements.

Teaching number sense gives kids a deeper understanding of our number system, which will in turn prepare them for the algebraic equations to come in the upper elementary grades and middle school. You can create a strong foundational knowledge of number sense with this guided lesson, which provides third graders with targeted instruction and exercises designed by our team of curriculum experts.

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.

This guided lesson builds upon third graders' understanding of multiplication in order to further develop fluency with this operation. The lesson first reinforces the various strategies for doing multiplication (for example, repeated addition), then teaches kids to apply those strategies within practical exercises. Designed by our team of teachers and curriculum experts, the goal is to provide numerous ways to conceptualize multiplication problems.

This year, third graders will build a stronger understanding of division. This guided lesson uses the repeated subtraction strategy as a way of teaching division. The lesson shows how division problems can be solved by repeatedly subtracting the same number (the divisor). Not only does this help students solve division problems, but it also builds a conceptual understanding of division. For more practice, check out the suggested division worksheets.
