## Conceptual understanding for math learning success

### Deeply personalized, adaptive, standards-aligned

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.

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.

## Grade 4 Teacher Tools & Sample Lesson Plans

Ready to use in Grade 4 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.
