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).

In this lesson, kindergarteners will be given the chance to focus on their counting skills with engaging exercises and guided instruction. Just as identifying the letters of the alphabet is a precurser to reading, so is counting to developing math fluency. Soon, your child will learn that the numbers they are counting have associated values, so the more practice they can get with counting the better.

Geometry in kindergarten involves the basics of measurement, shapes, and spatial reasoning. Designed and reviewed by teachers, this guided lesson gives kids an overview of these concepts with clear instruction and engaging exercises. Geometry practice in kindergarten can help bolster the skills needed for higher-level concepts in the later grades. You can give kids even more practice by downloading and printing the accompanying worksheets.

Understanding data and graphs is a critical skill that we use on a regular basis to read news articles, reports and other media to interpret information. In this unit, students investigate data collection, data organization and visual representation in different kinds of graphics (i.e. line plots, pie charts). Learners also apply concepts of probability and statistics to analyze data.

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.

Flexibility and fluidity with addition is an important part of the first grade math curriculum, but it takes lots of practice to gain confidence with this skill. This lesson in addition offers guided practice which aims to increase mental math and fluency with addition. When your child finishes this lesson, you can continue the addition practice by downloading and printing the accompanying addition worksheets.

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.

First graders' fluidity with comparing numbers is an important building block for the higher-level math concepts to come in the later grades. You can give first graders a leg up with this lesson, featuring guided instruction and practice problems in comparing numbers. Once kids get through this lesson, you can download and print the suggested comparing numbers worksheets in order to provide even more opprotunities for practice.

Teach kindergarteners all about the numbers 0 to 10 with this guided lesson which focuses not only on recognizing numbers, but beginning to understand their value. Each exercise aims to illustrate the values behind each number in an engaging way, making early math a fun occasion. If you wish to extend the learning after the lesson is over, check out our accompanying numbers worksheets.

Kindergarteners build upon their number skills in this guided lesson which focuses on the numbers 11 to 20. Not only will kids learn to identify numbers, but also begin to associate them with certain values. It's an important concept for young mathematicians that requires lots of practice. You can give kids even more chances to extend learning with the accompanying numbers printables.

Fractions can be challenging when taught in an abstract way. That’s why this unit invites learners to engage with fractions and mixed numbers in very visual and concrete ways using number lines, tape diagrams and area models. Students will learn different strategies to practice identifying and generating equivalent fractions.

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.

Students are going to take a deeper dive into fractions in this unit! Learners will apply previous understanding of finding equivalent fractions, and converting between fractions and mixed numbers to work with fractions in more complex ways. Students will continue to use visual models to learn and practice adding, subtracting, multiplying and dividing fractions.

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).

This geometry unit engages students in analytical thinking as they learn about the properties of two dimensional figures and consider the different ways they can be sorted based on those properties. Students also learn to plot points, lines and shapes on a coordinate graph.

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.

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.

This year, first graders will be introduced to place value and our base 10 number system, usually by starting with 2-digit numbers (100 or less). This guided lesson helps introduce place value to first graders through instruction and examples targeted to this skill. If your child finishes the lesson and needs more practice with place value, download and print the accompanying worksheets suggested by our curriculum team.
