Place Value (Beyond Base 10)

This is just a preview! Byrdseed.TV opens for new memberships on December 2nd. Join the wait list to get more information.
 

To better understand place value, we venture beyond the decimal number system and explore a Base 9 system. Students will be exposed to ancient Babylon’s Base 60 system and computers’ Binary and Hexadecimal before creating their own number system!

This lesson includes 4 videos for students to work through independently.

Place value is something we cover in elementary school. It seems simple, but I'd wager that very few adults really understand the topic. I sure didn't until I worked with non-base-10 number systems in college. Your students can get a taste of this mind-boggling experience by imagining what it would be like if we didn't have the number 9. What would each digit represent then?

"I just subscribed to Byrdseed.TV and am loving it -- though it is kind of scary addictive in a binge-watching kind of way (that, by the way, is a compliment)." ~ Elizabeth from Florida
