KS3 Data Representation: Binary, Denary and ASCII Complete Unit

A complete, binary-themed unit that takes KS3 classes from “why do computers use 0s and 1s?” to converting numbers, storing text and decoding pixel pictures. It has six editable PowerPoint lessons, a work booklet, a homework booklet and full answers.

The slides use a black “matrix” look with falling binary. The level counter is shown in binary, and your XP is shown in both denary and binary.

The six lessons

Why Binary? Bits, Bytes and Units: on/off switches and the units from bit to terabyte
Base 10 and Base 2: place values and how many values n bits can store
Binary to Denary: a 3-step method with worked examples, plus “Binary fingers”
Denary to Binary: a 4-step method, common mistakes and checking your answer
ASCII: Text as Binary: a printable ASCII table and a decode challenge
Binary Pictures and Secret Codes: 1-bit and 2-bit pixel pictures, colour depth and a shift cipher

Varied activities

Putting units in order, spot the mistake in conversions and an even-or-odd card sort
A “crack the code” binary puzzle that spells a hidden word
ASCII matching, a binary badge design task and a pixel picture design task
A decision task on choosing the right colour depth
