First, students checked their answers to homework assignments for the first 30 minutes.
Students then had 30 minutes to complete Embedded Assessment 1 in Unit 3 (p.273-274).
For the last 30 minutes:
Ex.) Find the number whose square is the product of 4 and 16.
Interpret the above statement as x^2=4•16 -> x^2=64, so x=8.
We say that 8 is the geometric mean of 4 and 16.
The geometric mean of two numbers is the number whose square is equal to the two numbers’ product.
If x^2=a•b or x=sqrt(a•b), then x is the geometric mean of a and b.
We then completed the following WS: Geometric Mean
