### Thursday April 25th- Pledge Plans

We just covered looking at linear equations in terms of walking rates (distance and time variables).  Today we will focus on pledge plans using the variables of distance (x) and money raised(y).

Our goals for today's lesson were:
• construct graphs and tables to model problem situations.
• translate information about linear relations given a table, graph, or equation.
• explore what a y-intercept means in an equation.

Here is the graph for Investigation 1.3 Problems A-C.

### Wednesday April 24th - Investigation 1.2

Today we started with the following entry slip.
Those needing more practice with the vocabulary should look to the last post.

We also looked at walking rates and the following formulas:

Speed = distance/ time

Distance = speed x time

Time = distance / speed

Continue working with Google Graphing Calculator.

### Monday and Tuesday April 22nd and 23rd

We started a new unit- Moving Straight Ahead today.

The Units first Investigation focuses on:

• Understanding patterns of change between independent and dependent variables for linear relationships.
Here are the notes from today.  These terms are all review from previous units.

Linear relationship or function: “A relationship in which there is a constant rate of change between the two variables.”

Ex: y= 4x + 10

Independent variable (x-value): “A variable that isn’t effected by the other variables. Stands alone.”

Ex: (4,10) (6,2)

Dependent variable (y-value): “A variable that depends on the independent variable.”

Ex: “For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.”

y - Intercept: “Location where the line crosses the y axis.”

Coordinate Pair: “A pair of numbers in the form of (x,y) that gives the location of a point on a coordinate graph.”

Ex: (4,6)

Coordinate Grid: “A grid in which you can plot coordinate pairs, on the axis of (x,y).”

Hi All,

Today we continued our work on Investigation 4.3 about the Distributive Property.  We worked with multiplication over both addition and subtraction.  The students also did well to take their knowledge of the order of operations and positive and negative numbers to help expand expressions.

To help drive the property home, I thought I would share a helpful link from cool math.com:

COOL MATH --DISTRIBUTIVE PROPERTY

Remember, Skills #17 is due tomorrow! :)

## 4.3 The Distributive Property and Subtraction

Hi All,

We continued our work with the Distributive Property today and began to shift our focus from working with multiplication and division to working with multiplication and subtraction.

Our Goals for the Day:
1. Develop and use the Distributive Property of multiplication over subtraction.
2. Use the Distributive Property to solve problems.
Here is a look at the notes we took today.  Be sure to take the time to review these notes and your own so that you are confident and ready to continue our work on 4.3 tomorrow!

**Also be sure to keep working on Skills #17 and reworking any problems you had incorrect on the Skills #1-16 Quiz last week.

### 4.2 Notes

Hi All,

Here is a sample of the notes we took in class from Investigation 4.2 Distributing Operations:

Be sure to check out the Homework Calendar to see what your class has assigned.  The Devils and Tweeties will be back on the same page tomorrow!

## Monday, April 1, 2013

### Monday-Tuesday, April 1-2, 2013

This week we are focusing on honing our SKILLS!

The Devils jumped right into Distributing Operations on Monday:

Our goals were to:

1. Model the Distributive Property with areas and rectangles that have edges subdivided.
2. Develop and use the Distributive Property of multiplication over division.
The Tweeties took time to practice the Order of Operations with some ACE Questions and work on their Skills Quiz from last Friday.

Tomorrow, we will flip roles and the Devils will work on the Order of Operations/Skills while the Tweeties will tackle Distributing Operations
