Multiplication: Open Arrays Play this 4th grade math lesson

Multiplication: Open Arrays

This DreamBox lesson ensures students connect partial products to a concrete area context on the open array. Students learn to efficiently choose and solve partial products that enable better mental multiplication with multidigit numbers. These lessons teach students to use multiples of 10 and the distributive property as powerful tools for multiplying and mental computation.

Subtraction Algorithm Play this 4th grade math lesson

Subtraction Algorithm

After students have learned number line and constant difference strategies for subtraction, these DreamBox lessons engage those students in learning the standard algorithm as another approach to solving subtraction problems. Using a context of shipping items from a warehouse, students have a concrete place value connection to the steps in the algorithm. Students learn and use appropriate notation while making sense of the algorithm.

Find the Factors Play this 4th grade math lesson

Find the Factors Snap Blocks

Students use our excellent Snap Blocks™ virtual manipulative to find factors for products up to 100 (50 on this sample lesson). Not only does this build understanding of the concept of multiplication, but it also gives students a foundation for understanding later concepts such as equivalent fractions and factoring polynomials.

Understanding Equivalent Fractions Play this 4th grade math lesson

Understanding Equivalent Fractions

DreamBox engages students in extensive lessons that develop understanding of equivalent fractions. In lessons leading up to this one, students learned that two monkeys dividing one banana equally each have the same amount as four monkeys sharing two bananas equally. This lesson builds on that understanding and uses a virtual manipulative called the ratio table, which helps students make sense of equivalent fractions and their relationship. These lessons ensure students understand that 3/4 and 6/8 have the same numerical value and are therefore equivalent. As a result of these lessons, students will also be able to take a given fraction, such as 2/3, and generate additional equivalent fractions (4/6, 6/9, etc.).

Comparing Fractions with Unlike Denominators Play this 4th grade math lesson

Comparing Fractions with Unlike Denominators

This DreamBox lesson ensures students think conceptually and critically about comparing fractions with unlike denominators. The lesson uses the ratio table to help students answer problems such as whether 3/4 is greater than, equal to, or less than 5/8. Throughout this lesson sequence, students reason deductively, think strategically, and develop fractional number sense as well as fluency with multiplication and division.

Subtracting Fractions with Like Denominators Play this 4th grade math lesson

Subtracting Fractions with Like Denominators

This sample lesson helps students think conceptually, not procedurally, about subtracting fractions. Engaging with virtual manipulatives unique to DreamBox, students make sense of subtracting fractions using the “removal” or “take away” strategy. Fractions in this lesson have the same denominator, and students represent the subtraction situations with formal equations. Students complete problems such as 1 3/5 – 4/5 = _. Lessons are designed so that students become skilled at subtracting mixed numbers and improper fractions fluently, mentally, and easily.
