Math Monday: Tornado Shapes & EF Scale


We moved from snail spirals to cyclones this week.
Whenever we can combine math and art, I'm in and it's usually not difficult to do.

We talked about tornado shapes and looked at three we have samples of in our Geometric Solids:
1) cone
2) cylinder
3) half sphere (in tornado terminology, "bowl")

We then drew the three samples (and someone added Dorothy to one of her twisters!)

One of the books we looked at outlined the Enhanced Fujita Scale, so we could examine how tornado's are rated according to their speed. http://kidspressmagazine.com/science-for-kids/misc/misc/tornado-rating-enhanced-fujita-scale.html#xEgl2tT3eKebwaBC.32

We also looked at safety measures, which were outlined in most of the books we read this week.


A condensed version of the original story.


A four hour+ reading of the 1900 original novel by L Frank Baum, in which Ms.O nearly completed in one sitting.
When we read the shorter version later in the week, she was adding the details which were missing!


I've heard multiple homeschool families rave about the Magic Treehouse Series.
Now I understand why.
Main characters, Jack and Annie visit the time-traveling tree house to experience historical events.
It touches on various, age-appropriate details of some very dark times.


We love and own the original Otis story, in which  an animated old tractor proves his worth on the farm by saving a new calf. 'Otis and the Tornado', has him helping animals again.
