Task 1

Create a solution in scratch which accepts a mark from the user and outputs whether or not the mark is a pass or a fail. Assume the pass mark is 50.

Solution: https://scratch.mit.edu/projects/699663431

Task 2

Modify your solution above to keep on prompting the user indefinitely and keep track of the number of marks entered.

In the above scenario, we add:

• a forever block to achieve indefinite/infinite repetition
• a variable to keep track of the number of marks, numMarks
• the join operator to output results

Demo:
1. Visit Scratch.mit.edu or open scratch version 3
2. Add the pen addon to the scratch project
3. Experiment with the blocks that use the pen
4. Draw a square of side 50 units

Scratch Demo: https://scratch.mit.edu/projects/650520375

Video Demo:

Task: Prompt the user to enter a value and store it in a variable called “Side”. Proceed to draw a square with a length of side equal to “Side”. (Assume the user enters a size that can fit in the stage area.)

In this example, we create a sprite which asks for you to enter a subject mark and tells you the grade.

Grade ranges are shown below:

We will be using a variable to store the users input.

Also, we will used some “if” blocks and logical operators to produce the grade.

See the blocks in the project below:

https://scratch.mit.edu/projects/629271195

Exercise

If someone enters an erroneous mark, e.g 1000 , the program dosen’t say anything to the user.

Copy or remix the project and Add blocks to say “you’ve entered an incorrect mark” if the user enters a mark higher than 100 or a mark less than 0.

(Hint: an IF block and an OR logical operator may be useful for solving this problem!)
