Addition Using the Open Number Line

The open number line is a powerful tool that helps students visualize making jumps forward and backward on a number line and use a variety of strategies for both addition and subtraction. These strategies include “Making Jumps of 10” (e.g. 79+33 = 79+10+10+10+3) and “Using Landmark Numbers” (e.g. 79+33 = 79+1+20+10+2). Students learn flexible thinking and efficient, accurate problem solving.

Addition using Compensation Buckets™

One of the most efficient mental math strategies is to turn hard problems into “friendlier” problems by making one of the addends a multiple of 10. For example, turn 23+38 into 21+40 by removing 2 from 23 and adding it to the 38. Kids start with smaller 2-digit addends, and when they’re ready they use 3-digit addends. Check out how we made this fun by using a bucket metaphor!

Grade 2 Teacher Tools & Sample Lesson Plans

Ready to use in Grade 2 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.
