Objectives:

Students will collect car cost comparison data from the "Car Wizard" web site to use as problem solving and calculations related to math.

Materials:

1. Student Worksheet
2. Computer and Internet Access
3. Calculators

Internet Resources:

Carwizard-Car prices, financing, information	http://www.carwizard.com/
Classic Cars-Pictures and Information on older models	http://www.classic-avenue.nl/

Procedures:

1. Have students do Worksheet #1 (HTML) / Worksheet #1 (PDF). This can be done at a one computer station as a Math Center activity.
2. Have students follow the directions on this student page while on-line.
3. Have Students find high and low price quotes.
4. Students calculate the requested items on worksheet based on the decisions they made on the web site.

Evaluation:

Data collection and accurate computation will be evaluated using a 3 or 4 point rubric.

Extensions:

Write about a future car elaborating on what features it might include. See Extension Worksheet (HTML) / Extension Worksheet (PDF) and draw a picture of your future dream car.

California's Mathematics Academic Standards

Grade 4:
Number Sense
2.0 Students extend their use and understanding of whole numbers to addition and subtraction of simple decimals.

2.1 estimate and compute the sum or difference of whole numbers and positive decimals to two places
2.2 round two-place decimals to one decimal or the nearest whole number and judge the reasonableness of the rounded answer

3.0 Students solve problems involving addition, subtraction, multiplication, and division of whole numbers and understand the relationships among the operations.

3.1 demonstrate understanding of, and the ability to use, standard algorithms for addition and subtraction of multi-digit numbers
3.4 solve problems involving division of multi-digit numbers by one-digit numbers

Mathematical Reasoning
1.0 Students make decisions about how to approach problems.

1.1 analyze problems by identifying relationships, discriminating relevant from irrelevant information, sequencing and prioritizing information, and observing patterns
1.2 determine when and how to break a problem into simpler parts

2.0 Students use strategies, skills, and concepts in finding solutions.

2.1 use estimation to verify the reasonableness of calculated results
2.2 apply strategies and results from simpler problems to more complex problems
2.4 express the solution clearly and logically by using appropriate mathematical notation and terms and clear language; support solutions with evidence in both verbal and symbolic work
