This document outlines a lesson on using Python for math calculations and combining math and text. The lesson objectives are to learn how to use Python for math calculations. The outcomes are that students will be able to use text and math in Python programs. The lesson covers escape sequences, basic math calculations, combining math and text using operators, and formatting numbers. Students complete tasks on a worksheet to practice these skills.

2. LESSON OBJECTIVES
 Learn how to use Python to work out
maths calculations.

Open Python Shell and have a go at the
calculations in the table below:

6. MINI PLENARY
In pairs try
the Mini Plenary task on Worksheet 2.
Did the calculator
beat Python??

7. [ slide 7 ]
COMBINING MATHS & TEXT
What will the output from this code produce?
>>> print("11 divided by 4 = ", 11//4,
"remainder ", 11%4)
>>> print("111 divided by 4 = ", 111/4)
>>> print("11 divided by 4 = ", 11/4)
Now try Task 3 on Worksheet 2.
Lesson outcomes
 I can use more text in Python ...
 I can use basic maths in Python ...
 I can use both text and maths in Python
programming ...

8. MORE TEXT AND MATHS ...
We can use text to label numbers for example:
coins = 20 Why???
Reason: If we need to demonstrate how many
coins we own more than once and the value of
the coins change, we only need to change the
number at the start of the program once.
As programmers this can saves us lots of time.
Now try Task 4 on Worksheet 2.
Lesson outcomes
 I can use more text in Python ...
 I can use basic maths in Python ...
 I can use both text and maths in Python
programming ...
