Rusty's Treasure Hunt - Part 1

Learning Objectives Define an algorithm as a set of steps. Explain that instructions must be in the correct order. Create a simple sequence of instructions for a task. Follow a short algorithm to predict an outcome. Identify a mistake in a simple sequence of steps. Give clear instructions to a friend acting as a robot. Can you help Rusty the Robot 🤖 find his favorite red ball? 🔴 We will learn how to give special instructions called algorithms. This helps our robot friend Rusty understand exactly what to do. Let's be great robot helpers! Real-World Applications Following a recipe to bake cookies 🍪 Getting dressed for school in the morning 👕 Building a tower with blocks 🧱 Brushing your teeth step-by-step 🦷

TermDefinitionExample Robot 🤖A machine that follows our instructions.Rusty is our friendly robot who needs our help. InstructionOne single step for the robot to do.A single instruction is 'Move Forward'. AlgorithmA list of instructions to finish a task.An algorithm to get a toy is: 1. Walk. 2. Pick up toy. SequencePutting instructions in the right order.First, put on socks. Second, put on shoes. That is a sequence. ProgramAn algorithm written for a computer or robot.We are writing a program to help Rusty find his treasure. Bug 🐞A mistake in our instructions.Telling Rusty to turn left when he should turn right is a bug.

One Step at a Time Robots only do one instruction at a time. Give your robot one clear instruction for each step. Don't combine them. Order Matters! Instructions must be in the correct sequence. If the steps are in the wrong order, the robot won't get to the treasure! Be Super Clear Instructions must be simple and exact. A robot doesn't understand 'go over there'. Use 'Move Forward 2 steps'.
