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).

Learn to count and identify numbers up to 20 in this guided lesson! 

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.

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.

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.

Understanding our base-ten number system is the foundation for many skills to come. In this unit, students will add on to their understanding of place value and extend to the millions! They will also learn how to read, write and order larger numbers, in addition to decimals to the tenths and hundredths.

In kindergarten, kids will learn all about sorting and classifying. This skill is a building block for math and science concepts to come in the later grades. Knowing how to group numbers, for example, builds a key understanding of numerical concepts. This lesson focuses on sorting and classifying skills for kindergarteners, and comes complete with suggested worksheets for extended learning.

In first grade, kids will learn how to tell time using both analog and digital clocks, a skill that can be tricky to master. Give kids lots of extra practice with this guided lesson in first grade time, designed by our team of curriculum experts and teachers. If kids need extra support in a printable format, check out the accompanying time 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.

Comparison is one of the most crucial math skills second graders learn, because it can be applied to so many other disciplines across the elementary school curriculum. In this measurement and data lesson, kids will work on object comparison and graphing. The exercises ask kids to list objects in size order, estimate length, note differences in length, and make bar graphs.

The ability to compare numbers with ease is crucial to understanding the relationship between numbers, also called number sense. The abstract nature of number sense makes extra practice crucial. This guided lesson helps kindergarteners to learn this skill with targeted instruction and engaging exercises. Further opportunities for practice can be found in the comparing numbers worksheets suggested to go along with this lesson.

Learning to add single-digit numbers is a highlight of the kindergarten math curriculum. You can support addition fluency with this guided lesson that takes kindergarteners through an understanding of values. Kids will learn with focused instruction and practice that by putting numbers together, they get a new number. When the lesson is over, kids can continue practicing addition with our accompanying worksheets.

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.

This year, second graders will be introduced to the concept of multiplication using repeated addition. For example, they will learn that 5+5+5+5+5 is the same thing as saying 5x5. This guided lesson will use manipulatives to teach kids about repeated addition and give them plenty of opportunities to practice addition within 100. Download and print the accompanying worksheets for even more addition practice.

Learning three-digit numbers can be a challenging part of the math curriculum for many second graders. This lesson helps to support second graders' understanding of larger numbers by teaching them place value. Kids will compare three-digit numbers and learn to count up to 1000 with guided instruction. When the lesson is finished, consider printing out the corresponding worksheets recommended by our curriculum designers.

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.

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 guided geometry lesson takes second graders on an exploration of 2D and 3D shapes. Kids will learn how to sort shapes, as well as partition them into halves, quarters and thirds. Tangrams are also featured within the exercise in order to give kids practical ways of practicing their new geometry skills. For more printable practice, try the geometry worksheets recommended by our curriculum advisors to accompany this lesson.

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.
