Algorithm
A set of instructions or rules a computer follows to solve a problem or perform a task.
Help me explain to...
K-5th
An algorithm is like a set of instructions or a game plan. In the classroom, we can think of it as a step-by-step way to complete a task, like following a recipe or building with LEGO.
6-8th
Students learn that algorithms help computers sort, search, or decide things. It's not just code, it’s also the logic behind what appears on their social media or school tools.
9-12th
This concept lays the foundation for understanding computer science. Algorithms drive search engines, navigation apps, and nearly every AI system. Knowing how they work helps students analyze digital decisions.
Expeditions
K-5th
Give each student a task like 'tie your shoes' or 'make a sandwich.' Have them write every step. Then swap with a partner and act it out. Discuss what happens if a step is missing.
6-8th
In pairs, students write instructions for sorting objects by size or color. Then trade with another group and 'debug' any confusing steps. Connect this to how computers learn from data.
9-12th
Ask students to write a basic algorithm to decide what after-school activity to do (based on mood, weather, time). Then compare how AI uses logic trees or flowcharts to make decisions.
