Algebra

Ok this is fresh in from Mr. Brown. I asked him to rate (0 to 5-high) what the kids covered in 8th grade (non-algebra) regular math. This will help us build our 9th grade intermediate algebra class that we need to have in place 2012-2013. Here is my suggestion anything with a 5 or 4 needs reminder/review anything with a 3 or less will need a full day > > Ch 1: variables, expressions, PEMDAS, real number and #line and their properties,add, subtr, mult, and dividing real #s > Ch 2: solving linear equations equation, including linear ones, ratios, proportions, percents > Ch 3: solving linear inqualities, absolute values, union and inter of sets, > Ch 4: intro to functions, linear vs non-linear, patterns, graphing, relations vs functions, notation, sequences > > Ch 5: rate of change, 3 > direct var, 0 > slope-intercept, 4 > standard form, 0 > parallel and perpendicular lines, 1
 * score : 5 notes:
 * score: 5 notes: not as much on ratios, proportions and percents in 8th grade, The standards say that these should be hit more in 6th and 7th grade, but I don't know if that has been done
 * score: 1 notes:
 * score: 4 notes: emphasis on linear

FYI. This will/should be our new name for Alg. 1 as per state requirements (No linear algebra as high school credit). Plus we need to continue adapting and pushing that course and the next so we are doing very little that is linear. I would suggest that we should be beginning with a review of linear equations and then jumping into chapter 6 (systems)

A nice [|way] to cement the concept of function vs relations

Here is a [|tasty way] to find the line of best fit on some real data.


 * Our current Algebra Content**


 * **Simplifying Expressions + Distributive Property**


 * **Functions**


 * **Investigating Slope & Y-Intercept**

here is a good [|applet]for scatterplots
 * **Writing Equations**
 * 1) [|Here] is an geogebra file for finding the equation of a line from two points


 * **Systems of Equations**
 * 1) A racing [|example] of systems.
 * 2) A great [|applet] for graphing systems of inequalities.
