Today's Lessons

2.6 inches average difference. Jake says " it was very cool when I worked on it." He was way off on some measurements, but he got his toe and smile exactly right. His pointer finger and his ear were very close.
He wanted to play with the calculator, so I taught him how to find an average. We did this when we were averaging his measurements. I showed him how a teacher averages a grade, and how a meteorologist averages the temperature and rainfall.
We also learned about the difference between human hands and feet, and lower primate hands and feet, and the difference between the pelvises. We tried to walk like an ape, and learned why it is important that we walk upright (so we can use our hands to create).

Update: forgot to mention that the subjects covered were Math, Science (including a bit of meteorology), handwriting, using a calculator.
