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.
