Updated marks

Nov 22nd - Test on Friday :)

You have two things to review and hand in on Friday:

The first four questions on the word problem worksheet.  Questions on the test will be similar to these ones.  Show me ALL of your work.

The six practice questions with solving rational numbers.

THERE WILL BE A EXTRA TUTORIAL THURSDAY AFTER SCHOOL.

Solving equations with rational numbers

We learned two methods for solving today.

1. Cross multiplying works when we have one term on either side of the equation.

2.  We can also multiply all terms by the Lowest Common Multiple to eliminate denominators

HOMEWORK:

Finish the front and back of the worksheet.  On the front side, you can use either method.  On the backside, you will have to use LCM.

Nov - Dec - Jan Plan

The semester is going by very quickly.  Here is what we have left...

•  Nov 21 - Nov 25: Word problems and solving with rational numbers (not any harder that we've done, just one more step to eliminate the denominators)
• Nov 25: Mini-test

• Nov 28 - Dec 2: Career education with Mr Colvin

• Dec 5 - Dec 14: Two week unit on scale diagrams, similar triangles, and ratios
• Dec 14th - Unit 3 test

• Dec 16th - Christmas Follies
• Dec 17 -  Jan 1: Christmas holidays

• Jan 3 - 13: 2 week unit on statistics and financial literacy
• Jan 13th - Unit 4 test (hopefully)

• Jan 16 - 20: Review of everything from the year
• Jan 24th - double block review day in afternoon
• Jan 25th - final exam covering everything :)

November 14 - Test Day tomorrow :)

Today we did reviewed material for the test.  Things to know:

• How to find slope from
• a graph
• an equation
• a table of values
• How to find the y-intercept from
• a graph
• an equation
• a table of values
• How to graph using
• an equation in slope-intercept form
• a table of values
• ordered pairs
• How to find an equation from
• a graph
• table of values
• when given the slope and the y-intercept
• How to change an equation from Standard Form to Slope-Intercept Form
• How to change an equation from Slope-Intercept Form to Standard Form
• Solving equations with one variable

I will have some definitions.  Here are a few I could consider:

• y-intercept, x-intercept, linear equation, slope intercept form, ordered pair,  quadrant,

I could also have you label stuff.

You'll be great!

Marks going into the test...

Writing equations from a word problem.

We started looking at creating an equation from a word problem / pattern.  We will go over this again in our double block, but here is an example:

STEPS:

• create a table of values
• is the pattern a linear one?  (does x and y go up/down by the same amount each time?)
• rise = change in y's
• run = change in x's
• slope = rise/run
• go 'backwards" one spot on your graph to see where the y-intercept would be (green)
• If you need to, draw a graph to see the slope and y-intercept.

Monday, November 7th

Today we were cutting and gluing - fun stuff.  We were going back and forth between graphs, slope-intercept form and standard (general) form.  Some of this is grade 10 stuff and you all did great!

Tomorrow, some word problems ;)

Here are some updated marks

November 3

You all worked really hard today and probably have cramped fingers.  Nice work!

Today we worked on four sheets to help us solve equations:

• solving equations with one variable and one step
• solving equations with one variable and two steps (which you seemed to find easier than the first one)
• solving equations with one variable and multiple steps - added brackets
• solving equations with one variable involving combining like terms

We did a quick teaser on tomorrow's lesson where we will be solving equations with two variables in order to put an equation into slope-intercept form.

HOMEWORK - complete and hand in the package of sheets from today.

November 1st

More practice today with slope-intercept form.  We practiced going from the graph to an equation and how to go from the equation to a graph.  Tomorrow we will be working on solving equations so that we can put all equations into slope-intercept form.

We did a class group quiz and everyone got 100% - nice work.

HOMEWORK - Graph the 8 equations I put on the board.  Most of you have already handed this in.
