Sam’s 4-6th Math Class
This week we dug into concepts related to ratios and fractals. We watched the thought provoking Nova episode: Fractals the Hidden Dimension and then talked about what it means to be “self-similar” and how an object can have a finite area but an infinite perimeter.
It was also very interesting that in their Morning Meeting presentation about Wildlife in Michigan, they mentioned the length of the coastline, which led us to another discussion about fractals and measurement related to “How Long is the Coastline of Britain.”
Algebra and Pre-Algebra
The 7th and 8th graders have mostly been completing assessments this week. All of the groups also had some new material introduced. The pre-algebra group started a unit on factors, fractions and exponents; the beginning algebra group is learning how to write the equations of lines from points or graphs and the completing Algebra group has started working with square roots and quadratic equations.
