Pie Chart Geometry Lesson 

We continue with our Waldorf Geometry main lesson block with this lesson on bar graphs and pie charts. We used data on the tree population of California as it was relevant to our Botany lessons rather than using the data that was provided in the main lesson book by Live Education Waldorf curriculum.
This is the data we used for the pie chart and bar graph:
Conifers make up 51.1% of the trees of California with a division within this category as follows:
Other conifers 17.2%, Ponderosa 14.1%, Jeffrey Pine 6.3%, Douglas Fir 5.6%, White Fir 4.5%, Red Fir 3.4%
Hardwoods make up 26.4% of trees with a division within this category as follows:
Other hardwoods 9.6%, Coastal live oak 6.3%, Tanoak 4.5%, California black oak 3.9%, Interior live oak 2.6%
Mixed conifers-hardwoods 14.5% and other 8.9%

We constructed a bar graph with this data as well.
For this lesson you will need a compass, protractor, ruler, calculator, Main lesson book and pencil.
The math is proportion math with 360 degrees/X = 100%/ (insert % of tree)
