OCR - Python Lesson 4 - Arithmetic

This lesson introduces students to using operators such as Add, Subtract, Multiply, Divide and Exponentiation. They're also introduced to Mod (working out the remainder) and Quotient (working out the whole number). They're given a number of activities which allow them to apply some of this and will attempt working out the median and mean. After this they're given an activity which gets them to work with the OCR structure. They're required to decompose a problem, list success criteria and build a sleep calculator. They will need to list their variables and on top of this will also need to show the development of their code. The worksheet can be typed in.

All operations are explained: -
num1+num2
num1-num2
num1*num2
num1/num2
num1**num2 for exponent
% used to explain remainder
// used to explain whole number part of division

Students given extension task / independent research task for finding out the mode.
