Give
specific information. TEKS addressed:
(A) use multiplication and division of whole numbers to solve
problems including situations involving equivalent ratios and rates;II.
Performance or learner outcomes
(B) represent ratios and percents with concrete models,
(C) select and use appropriate units, tools, or formulas
to measure and to solve problems involving length (including perimeter),
area, time, temperature, volume, and weight;
Objectives:
- Students will be able to:
- determine rate, if given time and distance
- Explain the relationship between rate, time and distance
- Use rates to model distance and position
III. Resources, materials and supplies needed
IV. Supplementary materials, handouts.
Activity sheet
Clipboard
RC Cars
Five-E
Organization
| Teacher Does | Probing Questions | Student Does |
| Engage:
The students will be divided
into groups of 4. Each group will be given a remote controlled
car. The students will write down what they believe the top
speed of each car is and how long it will take the car to reach top
speed. |
|
20
mph, 15 mph, etc… |
Explore:
The students
will be taken to a course previously set up by the teacher.
Each group will be given a stopwatch, and clipboard, an activity
sheet, and a tape measure. The students will then be asked
to complete the activity sheet. Now even though the students
are given some freedom in the activity the teacher must monitor
to ensure that the students stay on task and that they do not misuse
the RC Cars. |
How could the cars be made
faster?
What are some instances where a quick acceleration is safe?
Is there any point to owning a car that can go 240 mph?
|
Make them lighter, Mathe
the engine stronger
To get out of the way of something
It’s cool
|
Explain:
The students
will present the data they received. They will also give suggestions
on how other ways that the class can obtain data that is more representative
of the car. The students will give quick answers to how they
would measure top speed and deceleration. The teacher will
also present the formula to figure out rate given distance and time.
|
Is there a better way to
obtain the data for the cars?
What is the relationship between all three, speed, distance and
time?
|
Time them as they are moving?
D=rt etc… |
| Extend / Elaborate:
The teacher will now present different problems
where the students are presented two of the three, rate, distance,
and time, and the students have to figure out the missing component.
The class will also go out and test the class recommendations on
how to determine top speed. |
|
|
| Evaluate:
The students will
use the data which they collected and their presentations as an evaluation.
