Python All-in-One Lesson 4.5 Data Types + Calculations - PowerPoint - Video - Lesson Plan

This is the lesson where students stop typing random inputs… and start writing programs that calculate correctly.

In Lesson 4.5, you’ll learn how Python handles user input, why input starts as text (string), and how to convert it into the correct data type so calculations work properly.

This lesson is built for:
GCSE Computer Science teachers (cover work, homework, in-class)
Students learning Python from scratch
Anyone who keeps getting errors like: “can’t add str and int”
