JUMP123 – Times Table Generator

Predict, evaluate, and reflect

Read (don’t run yet) and predict what the starter code will output. Then evaluate quality and potential issues.

What does the program do?
(What happens when it runs?)

What could make it better?
(Is there anything you would change or add?)

Why was it made like this?
(What do you think the programmer wanted it to do?)

Why might the program not work?
(What could stop it from running properly?)

What kind of mistake or error could happen?
(Is it a typing error, logic error, or input problem?)

Focus Area	Question	Answers
Identify parts	What variables can you find in this program? (What are the names of the values that store data?)	Typical variables include `timesTable` (the number whose table you’re generating), `x` (the counter in the loop) and `answer` (the result of multiplying the two numbers).
Understand process	What does the `for x in range(1,11):` line do? (How many times will the loop run?)	`for x in range(1,11):` repeats the code inside the loop 10 times, with `x` taking the values 1, 2, 3, …, 10 in turn.
Explore change	What would happen if you changed the range to (1,6) instead of (1,11)? (How would that affect the output?)	The loop would run 5 times (x = 1 to 5), so you would only see the first five rows of the times table instead of 10.
Output formatting	What does the `f` in `print(f"...")` do? (How does it help display variable values in the text?)	The `f` makes it an f-string, which lets you put variables straight into the text using `{curly_braces}`. For example, `print(f"{x} x {timesTable} = {answer}")` shows the actual values of `x`, `timesTable` and `answer`.
Debug	What kind of error might happen if you removed `answer = 0` at the start? (Would the program still run correctly? Why or why not?)	If the program tries to use `answer` before it is given a value, Python will raise a `NameError` (variable not defined). Initialising it with `answer = 0` makes sure it exists before the loop starts.
Predict & Reason	What would happen if `timesTable` was a word instead of a number? (Think about what Python would do when it tries to multiply.)	If `timesTable` is a string (a word) and the code expects a number, you’ll either get a type error or strange behaviour. For example, `"3" * 4` repeats the text (`"3333"`) instead of doing a multiplication, and mixing a word with a number (like `"cat" * "3"`) will cause an error.

Focus	Task	✓
Change your previous program so that…	The user can choose which times table to display. (Use `input()` to let them type a number.)
What happens when you alter your program so that…?	Change the values in `range` so the generator outputs from 1 to 12.
Add to the program so that…	It shows the total sum of all answers at the end. (Add a variable to track the running total.)
Improve your program.	Add functionality for the user to enter how far the times table should go. 1. Create a variable called `maxValue` 2. Assign a value to `maxValue` through user input 3. Add a message explaining what to enter 4. Replace 13 in `range(1, maxValue + 1)` with `maxValue` 5. Test your code

Times Table Generator

You will create a quiz program that tests a player’s knowledge of their times tables.

Steps	Focus / Skill	Instructions
1	Create global variables	Make a variable for the times table number (`timesTable`) and how far to go (`maxValue`).
2	Output text	Print a welcome message and explain what the program will do.
3	Create inputs	Create inputs for the times table number and how far to go.
4	Use a for loop	Repeat each question for the chosen range of numbers.
5	Take input inside the loop	Ask the user for their answer each time.
6	Use variables in calculations	Work out the correct answer.
7	Use an if statement	Check if the user’s answer is correct or incorrect.
8	(Extension) Use a score variable	Add a score counter to track correct answers.
9	Output final score	At the end, show how many answers were correct.
10	Output a progress message	Add feedback based on score (e.g., Perfect score!, Great job!, or Keep practising!).
