Developing Understanding of Numbers, PK-1 - Online


Ever wonder why some children struggle to acquire a strong number sense and foundation for early mathematics and fluency? Have you worked hard – but to little or no success – trying to help older students abandon counting-by-ones strategies to add or subtract? Research and experience shows that it is critical for young children to understand and be able to visualize numbers as quantities, relate numbers to 5 and 10, and flexibly compose-decompose numbers. These understandings provide a strong foundation for students to flexibly use more efficient ten-based strategies to calculate.

In this course, you will learn how to use East West Math’s “visual karate” method. Visual karate, a research-based method, uses the ten frame to develop children’s number images with quantities. East West Math’s Visualizing to 20 Mastery Cards include ten frames, numeral cards, and story pictures that go with specially-designed activities and games.

In this course, participants will learn the following:

  • the importance of students’ understanding number as a quantity and how the ten-frame model helps students visualize numbers in this way
  • specific learning activities and games that develop understanding and visualization
  • techniques for observing, assessing, and keeping track of children’s progress

Format and Duration

This course is organized into five unit lessons, including the introduction. Each lesson will run 1 week for a total of 5 weeks. Convenient teacher access is provided 24/7. Learning time - plan for approximately 20-30 min per day or 2.5 hours per week.

Content and Activities

Each lesson will consist of an overview, readings, watching videos, discussion and assignments, including interacting asynchronously with others and keeping a reflection journal.

The course is divided into four sections:

Section 1, Lesson 1 gives the Nuts and Bolts of the East West Math virtual course structure. In this lesson, you will familiarize yourself with the course materials and introduce yourself to your classmates and teacher.

Section 2, Lesson 2, Research and Theoretical Background of East West Math’s Visual Karate Method, including why the ten frame is important for developing children’s understanding of number.

Section 3, Lessons 3-4 Learn to use the Visualizing to 20 Mastery Cards and visual karate method, including activities and games that are used with students.

Section 4, Lesson 5, Learn how to observe, monitor, and assess student progress and use the East West Math’s Basic Math Knowledge Assessment (BMKA)
