This quiz addresses part of the requirements of the National Curriculum KS1 for children aged 5 and 6 in years 1 and 2 in Computing. Specifically it is an introduction to algorithms, giving a definition of the term and some simple examples. It is one of 20 quizzes to help you find out about how computers work, and how they affect all our lives.
Computers are machines. They use electricity to make decisions. Computers have to be designed and built. Then when they are built, they have to be told what to do. That’s where algorithms come in. Algorithm is a hard word to say, and a hard word to spell! The definition of an algorithm is a list of steps to solve a problem or to get something done.














It’s not easy! Try writing it out

Codes come later


If the steps are in the wrong order, the algorithm will not work

The recipe is a list of instructions to make the cake


Can you write down an algorithm for walking once round the big red square?

This algorithm is just like the one with the big red square


All the steps in an algorithm have to be in the right order

Luke needs to open the tube of toothpaste before he can put some on his brush


Computers can be told how to add up, take away, multiply, and divide

It’s really good to write stories and poems, but it’s also good to be able to write algorithms
