Lesson 2: Plotting Shapes
You will explore the challenges of communicating how to draw with shapes and use a tool that introduces how this problem is approached in Game Lab. You will explore a Game Lab tool that allows you to interactively place shapes on Game Lab’s 400 by 400 grid.
Students will be able to:
- Reason about locations on the Game Lab coordinate grid
- Communicate how to draw an image in Game Lab, accounting for shape position, color, and order
Warm Up (10 min)
Communicating Drawing Information
We saw a lot of different programs yesterday, and you started to think about what types you might want to create. When we create a program, one of the things we need to do is draw everything on the screen. We’re going to try that with a “student” computer today.
One or two volunteers come to the front of the room and act as “computers” for the activity. They should sit with their backs to the board so that they cannot see what is being projected. Give each volunteer a blank sheet of paper.
Display: Project Sample Shape Drawing – Exemplar where it can be seen by the class.
You will need to explain to our “computer” how to draw the picture. In the end, we’ll compare the drawing to the actual picture.
Give the students a minute or two to describe the drawing as the students at the front of the room try to draw it. After one minute, stop them and allow the students to compare both pictures.
Prompt: What are the different “challenges” or problems we’re going to need to solve in order to successfully communicate these kinds of drawings?
There were several challenges we needed to solve in this activity. We need to be able to clearly communicate position, color, and order of the shapes. We’re going to start exploring how to solve this problem.
Activity (35 min)
Drawing with a Computer
Group: Get with a partner
Transition: One member of each group open a laptop and go to the contents for this lesson. There is a single level with a Game Lab tool.
Prompt: Working with your partner take two or three minutes to figure out how this tool works. Afterwards be ready to share as a class.
