Hexadecimal Puzzles

This free activity provides a hands-on, practical activity to help your pupils learn about binary to hexadecimal conversion and binary, denary, hex conversions. 2 different puzzles are provided in this resource which are simple to prepare and easy to include in your lessons.

SIMPLE HEX PUZZLE
In this puzzle pupils need to fit the triangles together so the matching edges are of equal value. One edge will contain a binary number and the other edge will have the corresponding hexadecimal value. Works well as an individual or paired activity. Includes the values from 1 to 15 (1 – F).

NUMBER BASES PUZZLE
In this puzzle pupils need to fit together squares so the edges match in value. Some are binary values, some are hexadecimal values and some are denary values. This is much harder than the simple hex puzzle and works well as a paired or group activity. Includes the values 0 to 255 (in denary).

HOW TO PREPARE THE PUZZLES
These are very easy to prepare and can be re-used with multiple classes.

You need one printed page for each puzzle you want to use, for instance if you have 30 pupils and want them to work in pairs you will need 15 copies of the puzzle.

Print on card or print on paper and laminate for longer durability.

Cut into separate shapes along the straight edges and put each set in a separate envelope.

Give one envelope to each pair of students and ask them to solve the puzzle.
You may want to provide some scrap paper for your students to use to work out the answers, especially for the number bases puzzle.
