Hands-On Math: Open Number Line Course

Build Number Sense, Promote Flexible Strategies, And Make Mathematical Thinking Visible 

Are your students stuck counting on their fingers or struggling to move beyond traditional algorithms for addition and subtraction? The answer lies in making their thinking visible.

The open number line is a flexible, student-driven tool that empowers learners to develop their own powerful strategies for mental math. By allowing students to model “jumps” and visualize the relationships between numbers, you can help them shift from tedious counting to efficient, flexible thinking.

In this short, focused micro course, you’ll discover practical strategies, classroom examples, and ready-to-use resources that will help you leverage open number lines to strengthen students’ understanding from kindergarten through high school.

Objectives:

• Use open number lines to model operations.
• Support student estimation and strategic jumping.

Target Audience:

• Math Teachers and Coaches 

Format:

• Self-paced eLearning course with interactive knowledge checks and real-world scenarios.
• The estimated time to take the course is 10 minutes.
• Downloadable Lesson Plan that you can use to support student understanding of adding rational numbers using open number lines geared to middle school students, and can be adjusted to meet the needs of your students.
• A completion certificate is available after completing the course.
