Understanding Algorithms and Data

What is an algorithm?

• A toy

• A list of steps to solve a problem

• A drawing

• A robot part

Why is it important for an algorithm to be clear?

• So it looks nice

• So it can be followed correctly

• To confuse people

• To save space

What do we call a mistake in an algorithm?

• Loop

• Bug

• Block

• Jump

What is debugging?

• Fixing errors in your program

• Building a robot

• Turning off the computer

Which is an example of a precise instruction?

• “Go fast”

• “Move”

• “Turn right and walk 3 steps”

• “Be quick”

What happens if a step is missing in an algorithm?

• It works better

• The result might be wrong

• It works faster

• The computer will fix it

Which action shows debugging?

• Starting a game

• Typing your name

• Changing a wrong step to a correct one

• Drawing a picture

Which of these is NOT part of an algorithm?

• A list of steps

• A funny story

• A goal to reach

• Instructions

When using a robot, what do you do before testing your new commands?

• Paint it

• Clear old instructions

• Turn off the lights

• Add music

If your program doesn’t work, what should you do first?

• Delete everything

• Check for errors

• Complain to your friend
