Understanding Equivalent Fractions Play this 4th grade math lesson

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

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

This sample lesson helps students think conceptually, and not simply 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.
