The Navigators participated in Global Math Week by investigating different bases and these first graders GOT IT!
We talked about powers of ten and watched Cosmic Eye. Lots of conversation was generated by this video.
Inquiry based learning: We watched the video "Exploding Dots" several times and just talked about what we noticed.
At first we noticed:
- It was funny when it exploded. Kaboom!
- There were lots of dots.
- The numbers changed.
Then we went a bit deeper:
- 12 is not 1100. It's wrong!
- It keeps on exploding when more dots are added.
- It explodes whenever there are two dots.
And even deeper:
- Two dots turn into one dot and goes into the next place over.
- It's like regrouping!
Ding ding ding! We're getting it!
Do YOU get it?
We then went on to take the tutorials/online experience at Explodingdots.org.
Do you see the light bulbs hovering above their heads?
