The Link between Linear Equations, Graphs, and Tables

Time really does fly when we are having fun.  It’s almost Christmas Vacation and we are all very excited to have some time off.  (Both the students and the teachers)  However, we need to buckle down and study hard in the next couple of days because we have a test on Thursday and Friday this week.  The test is on the Moving Straight Ahead text book.  Please do what you need to do in order to achieve your goal score for the test.

We had an opportunity to practice completing tables and graphs from a linear equation.  We worked on another T-shirt company “Sweet Tee’s” and their business model was C=5n+10.  The students and I picked apart this equation by determining what the slope and y-intercept was and what it meant to the situation we were given.

Homework is on pg. 58 #9 in the Moving Straight Ahead text book.

Gold Coins and Pouches

Today we worked on visual representations of linear equations.  $1 dollar gold coins represented a unit and the pouches represented more than one gold coin.  In these examples we found out how many gold coins each pouch contained by process of elimination and by keeping the equality of both sides of the equation. For example:

In this example we have 10 coins on the left and 4 coins on the right.  The 4 coins on the right cancel out 4 coins on the left leaving behind only 6 coins on the left and 3 pouches on the right.

This leaves 6 coins on the left to be divided up evenly between 3 pouches.  Their are 2 coins in each pouch.

Homework is in the Moving Straight Ahead text book, pg. 58 #5,6,7,8 and 10

Solving Equations

Thursday 12/9/2010 we worked on Problem 3.1 in the "Moving Straight Ahead" text book.  The goal was to have mastered solving equations by graphing, making table and by substituting in number for the variables.  For extra help on solving equations please the Math Help Sites page and look at the links below the heading "Algebraic Sense".

Friday 12/10/2010 we finished problem 3.1 in-class. 

Homework - Have a wonderful weekend :o)

Practicing Slope and Y-Intercept

Practice makes perfect.  I hope you students enjoyed the homework last night as it made connections between real life situations and slope/y-intercept.  Today we have an opportunity to finish our work in the Additional Practice packet (also called the “Slope/Y-intercept Packet”) making sure we al understand how to make connections between real life situations and the appropriate graph, table, and equation.

Entry Task was to write an equation that is parallel and one that is perpendicular to a given equation.   y = 4x - 12

Homework tonight (12/8/2010) is to finish our in-class work:  Slope/Y-Intercept Packet (Additional Practice Packet)  pg. 105 #7,8   pg. 110 #1,2,3,4,5

Parallel and Perpendicular Slope CONTINUED...

Wow, there goes Tuesday.  Time flies when you're having fun.  Many students had the opportunity today to practise more with parallel and perpendicular slopes and writing the corresponding equation.  For an entry task students sketched a line on a graph given only a slope of 4.  During class students had time to finish last nights homework as I went through a few of the problems for the whole class. 

Homework for Wednesday (12/7/2010):

In the Slope/y-intercept packet page 112 #1-10

Parallel and Perpendicular SLOPE

Our current unit is all about graphing lines from an equation.  This is being done by creating graphs, tables, and equations and making connections between all three of them. 

Today we had an opportunity to learn about Parallel and Perpendicular Slope.  To give you some extra support I would like you to visit CoolMath.com.  There are plenty of extra explanations within this website and fun math games that will both challenge your brain and add a little fun to everyday math.

Homework for tonight (12/06/2010):  Finish the Parallel/Perpendicular Slope Packet.

Welcome Welcome

I would like to take a moment and thank you for visiting my blog of math.  This blog is a great tool for any 7th grade math students and parent to receive extra help (but mostly for my students at Glover Middle).  There are a few things that need explaining about this site.  To the left is other math websites that will give step-by-step examples, mini lessons, math games, and much more online support.  This blog will also have weekly posts of past homework assignments so those students who were absent or think they are missing anything can catch up.

Thank you again for visiting and please stop by any time for updates about my classes and/or anything new in the math world.  And remember... Math is our friend!
