 November 16 ~ 20, 2009

Monday ~ Friday

7:30 - 8:00 AM

  

 

Week of:   November 16 ~ 20, 2009

CMP Math

Monday  11/16/09

Objective

(Student will…)

•     Gain an intuitive understanding of basic exponential growth patterns

•     Begin to recognize exponential patterns in tables

Teacher Activities & Strategies

Growing, Growing, Growing Unit:  Problem 1.1 (Pg 5) Exponential Growth

LaunchDescribe Chen’s ballot-making task.

Have students cut and stack paper for the first two or three cuts. This provides a visual aid for helping them understand the relationship between the number of cuts and the number of ballots created.

Encourage students to look for the multiplicative pattern in the table.

Summarize:  By asking about patterns in the table relating the number of cuts to the number of ballots, lead the class to a discussion of exponents.

Display the table from Problem 1.1 on the overhead and ask:

•  How did you get the number of ballots for 5 cuts?

Add a third column to the table and illustrate each calculation, showing each factor of 2.

Use the example below to introduce the terms base, exponent, exponential form, and standard form.

2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = 210

Explain that 1,024 is the standard form of 210.

•  How many ballots are there after 0 cuts?

•  How could we show this in our table?

•     Compare different exponential growth patterns

•     Understand the role of the growth factor in exponential relationships

•     Make a table from the graph and equation of an exponential relationship

Teacher Activities & Strategies

Growing, Growing, Growing Unit:  Problem 1.3 (pg 8) Making a New Offer

LaunchHave students read about the new plans and study the graph and equation.

•  How many squares are on the board for each new plan?

•  For each plan, how many rubas are placed on the first square?

•  What is the rule for placing rubas on each successive square?

Summarize:

Ask students which plan they think is best for the king and which they think is best for the peasant.

Objective

(Student will…)

•     Continue to investigate the role of the growth factor in exponential relationships

•     Compare and contrast exponential and linear growth

Teacher Activities & Strategies

Discuss Bell Work

Growing, Growing, Growing Unit:  Problem 1.4 (pg 8) Making a New Offer

Launch:

Review the terms exponential growth, exponential relationship, and growth factor.

Describe the last chapter in the saga of the king and the peasant.

Summarize:

In a class discussion, talk about groups’ findings for the problem. The important idea to explore here is the distinction between the exponential model (Plan 1) and the linear model (Plan 4).

•  Which plan would you advise the peasant to accept?

•  Do the plans increase in the same way?

•  What would the graphs look like if we extended them?

•  What causes this difference in their patterns of change?

Discuss the fact that Plan 4 favors the peasant for the first six squares, but Plan 1 is much more favorable thereafter.

Ask students about the equations:

•  What do the numbers and variables mean in the equations for Plans 1 and 4?

This question offers an opportunity to review equations for exponential and linear relationships.

Have a student add the information for Plan 4 to the class chart.

Monday/9

Objective

(Student will…)

•     Estimate lengths of hypotenuses of right triangles

•     Apply the Pythagorean Theorem to a problem situation

Teacher Activities

Looking for Pythagoras Unit:  Investigation 4.2 – Stopping Sneaky Sally  page 49

LAUNCH:

Introduce the baseball scenario described in the student edition. Talk about the layout of a baseball diamond, which is pictured on Transparency 4.2. The baseball diamond is a square. Let students offer a few estimates.

SUMMARY:

Have several students share their strategies for solving the problem. Look for specific references to the Pythagorean Theorem.

Stress the correct procedure: square each leg length first, add the squares, and then take the square root of the sum to get the length of the hypotenuse.

Tuesday/10

Objective

(Student will…)

•     Investigate the special properties of a 30-60-90 triangle

Teacher Activities

Looking for Pythagoras Unit   Investigation 4.3 – Analyzing Triangles page 50-51

LAUNCH:

Show a transparency of the Getting Ready for Problem 4.3. Tell the class that triangle ABC is an equilateral triangle and discuss reflection line of symmetry.

Students should discover that line segment AP divides triangle ABC into two congruent triangles. Remind students of the formal and informal meaning of congruent triangles.

In Problem 4.3, students will continue to explore these relationships about angles and side lengths.

SUMMARY:

Let several pairs share their reasoning about each question, demonstrating their work at the board or overhead.

Students should also discover that the length of the side opposite the 30° angle is half the length of the hypotenuse. In Question B, all students should be able to find the length of the third side of the right triangle using the Pythagorean Theorem. Use one of the two possible approaches to help clarify student confusion related to Part B.

Question C of the problems reviews the relationship in a 30-60-90 triangle.
