Tuesday May14 - Study Sheets for Investigation 2 Quiz

In Moving Straight Ahead, students will study some basic ideas of algebra and some ways to use those ideas to solve problems involving linear relationships and linear functions. In particular, they will be assessed on:

• Recognize problem situations in which two variables have a linear relationship to each other;
• Describe the patterns of change between the independent and dependent variables for linear relationships that are represented in tables, graphs or equations;
• Construct tables, graphs, and symbolic equations that express linear relationships;
• Translate information about linear relations given in a table, a graph, or an equation to one of the other forms.

Watch the Concept video and Problems 1 and 4.

Investigation 2 - Exploring linear functions

The goals for Investigation #2 are:

• Find solutions to a problem using a table or graph
• Understand the connections between linear equations and patterns in tables and graphs.
• Translate information about linear relations into tables, graphs and equations.
• Understand how the y-intercept appears in tables and equations.

Here are the notes from todays class on how linear relations are seen in tables, graphs and equations.

May 1st - Investigation 1 - Moving Straight Ahead

Today we reviewed and completed an additional practice worksheet in class.

Goals for today:

• Understand positive and negative rates of change and how they are represented in tables, graphs and equations.
• Continue to explore y-intercepts.
• Describe the information the variables and numbers in the equation represent.

Here is the Additional Practice and the answers to check your work.

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-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

Wed and Thursday 27th and 28th - Study Guide for Skills Test and Class Notes

Investigation 4.1  Goals:
This investigation focuses on the order of operations.
Students will explore the use of the order of operations to order computations in provided problems.

Tuesday 26th - Study Guide for Investigation #3

Accentuate the Negative - Check-in Investigation 3
Study Guide Essential Learning: 
• Demonstrate an understanding of arithmetic operations for integers (positive and negative numbers)
• Understand commutative property, distributive property and order of operations

Content covered:
1. Solve word problems involving positive and negative numbers Examples: Skill Sheet: Multiplying Integers
2. Solve problems involving addition, subtraction, multiplication, or division of positive and negative numbers Examples: Skill sheets (the papers with the circled problems)

 Study:
*Look over the first quiz from this unit. Make sure you can do any of the problems, especially any that were incorrect.
*Check the problems that you’ve marked wrong from your homework- redo them, if you can’t get the right answer, ask questions.
*Do some of the problems from the handouts and then check to see if they are right using a calculator. 

Vocabulary use be specific, use the terms we have learned – see the list in your vocabulary notebook and vocabulary crossword puzzle.
