The way to build a strong math foundation

Deeply personalized, adaptive, standards-aligned Grade 3 lessons

Multiplication Area Models

DreamBox uses area models to help develop multiplicative thinking. In a series of activities, a given rectangle is covered using smaller rectangles. As grid lines are removed, students work with open arrays. As rectangles are moved, students are exploring the big ideas in multiplication: distributive, associative, and commutative properties.

Placing Fractions on the Number Line

An understanding of fractions as real numbers with value and magnitude is fundamental to understanding the nature of fractions as well as how to perform fraction operations. This lesson engages students in actively placing fractions in their correct location on the number line. A number line representation ensures students understand how to compare and order fractions apart from any specific part-whole context. Instead of using a particular context—such as dividing an object into three equal parts—students use landmark fractions and numbers to place fractions on a number line, from 0 to 1 and from 0 to 2.

Constructing and Measuring Polygons I

In this lesson: they are creating shapes with a specific side length, then measuring the other sides using a ruler. Students construct triangles, quadrilaterals, and polygons, and use a ruler to measure their sides.

Grade 3 Teacher Tools & Sample Lesson Plans

Ready to use in Grade 3 classrooms with any type of interactive white board, DreamBox Teacher Tools are virtual manipulatives designed to help teach the concepts students need to learn—and to reinforce Common Core standards. Based on cognitive research that shows how children really learn, DreamBox’s engaging, high-quality virtual manipulatives help motivate and guide learners at every level to persist, progress, and achieve math proficiency.

Making math meaningful

These Teacher Tools help bring math to life for all students in large- or small-group instructional settings. Any teacher can use these online math tools—TenFrames, MathRacks, and other innovative tools—with your interactive white board or projector to make math lessons clear for your whole class.

Supporting professional development

When teachers access DreamBox Teacher Tools, they’ll also find tutorials about using the manipulatives and ideas for incorporating the tools into classroom lessons. And we provide resources that support the professional development of teachers as they learn to include the virtual manipulatives in their lesson plans.
