These worksheets were written for, and used in my Year 10 GCSE class to practice Huffman Coding.
There are 4 worksheets, some being hand-written.
- Creating Huffman trees from frequency tables (starting at 2 items in the table and increasing in difficulty)
- Creating tables of Huffman codes from trees
- Calculating the differences in bits between using ASCII and Huffman coding
- Extension task (which goes beyond the remit of GCSE)
These were designed specifically for the AQA Computing GCSE, but can be used for any level or board that teaches data compression.
