Algorithm Debugging Detective Adventure

Grade 3 Technology Finding and Fixing Algorithm Mistakes 30-Minute Investigation

What is an Algorithm?

A set of step-by-step instructions Like a recipe for solving problems Computers and people both use them Each step must be in the right order

What is Debugging?

Finding mistakes in algorithms Fixing errors so instructions work correctly Like being a detective looking for clues Making sure each step makes sense

Debugging Example: Brushing Teeth

Detective Training: Find the Bugs!

Work with your partner Read the algorithm carefully Circle any mistakes you find Write the correct steps Explain your fixes to others

Common Algorithm Mistakes

{"left":"Steps in wrong order\nMissing important steps\nUnclear instructions","right":"Steps that don't make sense\nForgetting to test the algorithm\nSkipping safety steps"}

Debug Detective Motto

'Every bug is a clue waiting to be solved!' Great detectives never give up Ask questions and test your fixes Work together to solve mysteries
