| Lesson 13 | Rounding float numbers | Using round() and specifying a number of decimal places | |
| Lesson 14 | Significant figures | ||
| Lesson 15 | maths functions | Click here to see the thinking process behind a program I have written. I take you through step by step. The program solves GCSE level quadratic equations. |

| Lesson 16 | Operators | Did Identity and Logical today - only one to go! | |
| Lesson 17 | Turtles | Great fun getting a turtle to draw a cube. I also did a page on turtle commands. |
16/10/2022 |
| Lesson 18 | I made a page explaining how 'turtles' came about. Then I made a program to draw an equilaterally sided figure of the choice of the user. |
17/10/2022 | |
| Lesson 19 | Incorporated code that directed the user to choose only an integer in a specific range. |

| Lesson 20 | A Halloween Greeting - a witch turtle drawing pentacles on a spooky castle background.
While doing this I set up a page on colour. |

| Lesson 21 | Great fun writing a program that will draw any number of points on a star. There are three methods to make it work... Odd number of points:
Even points, that halve to an even number (e.g. 8):
Even points that halve to an odd number (e.g. 14):
I also learnt how to change the position of the cursor with an address command rather than steering it there. |

| Lesson 22 | As a biproduct of the star program I have written a program that draws a 'flower' with petalsthat are 'kite shaped'.
The user chooses the number of 'petals'. I added to the colour page - explaining how figures can be filled with colour. I also started a page on circles. |

| Lesson 23 | A pumpkin Halloween Greeting.
|

| Lesson 24 | Today I added to the circles page - making it easier to understand. I also found out how to make an 'oval shape' - an ellipse.
I also discovered how to define a method - rather like creating a subroutine in Basic - orientate the turtle in one simple command, and make the turtle return home - turtle.home(). |

| Lesson 25 | Today I thought of Remembrance Day - and did a tribute to the fallen...
This includes a method for drawing the poppy - therefore calling on that would be possible with alternate sizes and orientation. Something for tomorrow maybe... |

| Lesson 26 |
This is a tribute to my Aunt - I received the sad news that she would soon 'pass' today... |
