This lesson focused on simplifying square roots as much as possible, with a focus on square roots of numbers that are NOT perfect squares.
We looked at simple equations that involved both square roots and cube roots and took some time to review factor trees and how they can be used to simplify square roots and cube roots.
We refined our work estimating square roots by not only describing a square root of a number (that's not a perfect square) as between two integers, but we also looked at a more precise estimate of the square root using fractions.
We spent our first day back from winter break looking at the Pythagorean Theorem and right triangles that have side lengths that are NOT integers.
In this lesson, we examined row relative frequencies and made determinations about the association of one variable to another. That is, does knowing the value of one of our categorical variables help us determine the value of the other categorical variable.
On Friday and today, we examined categorical variables, and completed two way tables. We computed row relative frequencies and began to look for associations in data.
For this lesson, we examined a few scatter plots, fit data to lines, and examined the meaning of the data in depth and made predictions. We completed this lesson Feb 5.
This lesson asked us to use exact linear models to evaluate scatterplots. We also looked at a few different Math Forum Problems of the Week. We covered this material on Feb 3 and 4.
Students use skills they learned earlier in the trimester to create equations for lines of best fit when evaluating scatterplots.
