This practical hands-on activity is best used to introduce pupils to binary for the first time. It takes about 20 minutes to make the calculator, following the instructions on page 2 (they will need scissors) which can then be used in the lesson to help the pupils convert from binary to denary values.

This activity helps towards of the coverage of the new computing national curriculum requirement of understand what algorithms are. An algorithm is a set of instructions. Help pupils learn about putting instructions into order using these cards. Ask the pupils to cut out each set and stick them in the correct order on paper or card. Cards 3 and 4 can have multiple answers and can form the basis for group discussion. A good activity to use before introducing the pupils to bee-bots.
