Computers need algorithms to work. They need to be told the steps to make things happen.

An algorithm is like a list of instructions. But it’s not just computers that need instructions. We do, too.

Which one of these everyday examples is an algorithm?

• A cake recipe

• Loud music

• Bright colours

• A poem

What is an

Algorithm?An algorithm is a step-by-step way of solving math problems faster than counting one-by-one. It's a set of instructions you use to find the answer faster, much like following directions to the store or following the instructions in a recipe for cookies. In this lesson, we'll look at the algorithms for addition, subtraction and multiplication.

1.When you are using an algorithm to solve addition, subtraction, or multiplication problems, write the problem _____________________.

• Vertically

• Horizontally

• Backward

• Mixed-Up

There is a big red square painted on the school playground. Mrs. Smith is a teacher. She takes her class out to the playground. Mrs. Smith gives instructions about how to walk once round the big red square.

Mrs. Smith asks Alice to stand at one corner of the big red square. Mrs. Smith tells Alice to walk to the next corner of the square. She then tells Alice to turn right.

What is Mrs. Smith’s next instruction to Alice?

• Walk backwards

• Turn right

• Turn left

• Walk to the next corner
