Week 3 Simplifying programming – repeating instructions and blocks
Objectives
  1. Demonstrate simplifying instructions; using repeat instructions/ loops to draw shapes#Visualize space, co-ordinates and shapes through movement and vice versa
  2. Visualizing the construction of a shape through a set of repeating instructions
  3. Taking inputs and executing instructions; assigning value to a variable, etc
  4. Demonstrate the logic of different repeating programming structures.
Hands-on Activity Activity #1 (Part A)

1.What was the answer to the previous question?

2.The turtle moved 8 times; how did we make the turtle do the action 8 times? (By clicking the start button)
3.Is there a way to give this instruction in a simpler way (encourage the class to think of a process being repeated multiple times)

4.Demonstrate the repeat command
5.We have repeated the command 8 times.
6.What are the other ways in which you would like to have the repeat command work? (When a condition is satisfied, for given input values)

Activity #1 (Part B)

1.What was the answer to the previous question?
The answer is given below.
2.The answer can be found her

Steps Activity #1

1.Draw any two different polygon with the repeat command. Students have to make a note of the number of repeat instructions and the instructions that are repeated

Steps Activity #2

1.Using the repeat command after taking inputs (defining variables)
2.A programme can take inputs; store value for a given parameter during executing a programme. This is called a variable and can be defined from the palette of variable blocks
3.A series of steps can also be defined as an action from this block

4.Let us construct a polygon of 8 sides and fill it with colour.
5.The first step is to define variable:
6.The next step is to repeat instructions to complete the shape

7.See shape to the side

Steps Activity #1
  1. Generate multiple shapes using repeat instructions
  2. Define input variables and repeat instructions to make shapes
Portfolio components

1.Study the picture below and answer the question
