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

• This video is hosted on YouTube

Pros

• Simple descriptions make lesson easy to understand

Cons

• No real use for the presented method of counting
