1. Variables

2. Todays Lesson  In todays lesson you are going to:  Learn to use variables  Learn to ask for user input  Learn to save the users response for use later  Use an if else statement to create a quiz  Learn to calculate a users score

3. Variables  A+B=C  If A=1 and B = 2  What is C?  A, B are variables. They can be changed.

4. Step 1  Getting a user input:  When the user answers their answer is stored by the computer.  You can use this answer in your program.  Can you get the program to ask the users name and then say Hi,. Extension: Create a conversation between the computer and the user.

5. Task  Create a quiz which asks the user a question.  The computer checks this answer is equal to the correct answer,  if it is CORRECT then it will say it is CORRECT  else it will say it is not right.  Use these building blocks to make your quiz.

6. Scoring the Game  Go to variables  Make a variable called score.  Set score to 0 at the beginning of the game  If the user gets a question right give them 1 extra score.

7. Experiment Time!  Time to have a play around with scratch!

8. Lesson 3  In todays lesson we will:  Revise asking for user input  Revise variables  Create a program to carry out maths calculations  Create a program to draw a shape based on user input.

9. Maths Challenge  Can you write a program that asks the user for two numbers, adds them together and displays the result?  Ask for a number  Create a variable  Set the variable to that number  Can you write a program that asks the user for the length of a rectangle and the height and works out the area?  Area of a rectangle is height x length  Can you do the same for  Speed  Volume of a cube  Area of a Circle  Find what the formula is online. Pi = 3.14

10. Task  You are going to create a program that asks the user to input how many sides they would like their shape to have and then you are going to draw a shape with that many sides.

11. Angles  There are 360  in a circle.  What angle did you have to turn when you drew a square.  What is 90  multiplied by 4?  What angle did you have to turn when you drew your triangle?  What is 120  multiplied by 3.  So to figure out what angle to turn you need to divide 360  by how ever many sides you have.

12. Task  Ask how many sides the user wants in their shape.  If they want 4 sides how often are you going to have to repeat your programme.  Think back to when you made your square and triangle.  Add a repeat that will repeat the program as many times as they have said.  You will need to drag their answer onto the if.

13. Get Going  Combine these actions to create your programme to draw a shape.  What do you need to do to get it to actually draw the shape?  Extension:  Can you get the sprite to come back to the centre every time the green flag is pressed?
