Sensing inputs
I can update a variable based on the state of an input.
These resources were made for remote use during the pandemic, not classroom teaching.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
Lesson details
Key learning points
- A variable's value can be changed according to a condition.
- Physical inputs can be tested as part of conditions in if...then...else statements.
- Checking the value of a variable doesn't change the variable's value.
Keywords
Input - data that is sent to a program to be processed
Sensor - an input device that allows a computer to collect data from the physical environment
Variable - a named piece of data stored in a computer’s memory which can be accessed and changed by a computer program
Common misconception
Checking a variable changes its value.
Reading a variable's value doesn't change it, only assigning it does.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
