Grade 4

Objectives:

- The students will show their knowledge of shapes within shapes by constructing the sail for the glider.

- The students will come up with at least one original idea for the use of the sail.

Procedure:

Step 1: We will use tangrams to show the students that different smaller shapes can help to construct larger shapes. An example of this would be four triangles to construct a square.

Step 2: The students can experiment with this for about 15 minutes coming up with their own examples of shapes within shapes.

Step 3: The students will construct the glider using K'nex in groups of two.

Step 4:
We will have a class discussion on what they learned and they will write in a math journal about how knowing about different shapes making other shapes helped them to do this activity.

Step 5:
We will discuss the sail and why it works. As a class we will come up with a written procedure of how the sail works.

Step 6: We will pair the groups off to work together. The two groups of two will use their glider to get to a final destination on the other side of the room. One group will have paper wind constructed prior to the lesson. One group will maneuver their glider across the room while the other group has the wind that they use to tell the group one where they are going. Group one then has to compensate for the wind to get to the destination.

Step 7:
The two groups switch roles and do the same activity.

Step 8: The students will start from scratch and make some kind of object using the sail. Example: They could make a car with a sail on it with the idea that it will help the environment.

Evaluation:

The students will have written in their journals about what they learned. We will be able to use this to see where each student stands. Also, if the students where able to get their glider to the final destination we will know that they understood how a sail works. We will have each group write about how the other group did as a form of evaluation. Lastly, if the students where able to come up with an original idea we will know that they understood that inventions can be used for other things, even if they are a little far fetched!
