Turtle art lesson 3

Week 3	Simplifying programming – repeating instructions and blocks
Objectives	Demonstrate simplifying instructions; using repeat instructions/ loops to draw shapes#Visualize space, co-ordinates and shapes through movement and vice versa Visualizing the construction of a shape through a set of repeating instructions Taking inputs and executing instructions; assigning value to a variable, etc 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 https://wiki.sugarlabs.org/go/File:TurtleCard-2.png How do we make the colours change continuously?
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 Generate multiple shapes using repeat instructions Define input variables and repeat instructions to make shapes
Portfolio components	1.Study the picture below and answer the question 2.Study the shape below and determine the Turtle code 3.Look at the following shape and guess the code. 4.Construct the following figures using Turtle http://neoparaiso.com/logo/ejercicios-de-geometria.html
