Instructional Ideas

  • Before viewing the end of the video (after seeing how to count on one hand), pause to have the class compute how high they can count on both hands
Classroom Considerations

  • One slide shows a hand with only a middle finger sticking up; make sure learners are mature enough to watch the video
  • Learners should be able to calculate using exponents of two

  • Simple descriptions make lesson easy to understand

  • No real use for the presented method of counting
