Lesson 5: Collecting Treasure with Laurel

Overview

In this series of puzzles, students will continue to develop their understanding of algorithms and debugging. With a new character, Laurel the Adventurer, students will create sequential algorithms to get Laurel to pick up treasure as she walks along a path.

Purpose

In this lesson, students will be practicing their programming skills using a new character, Laurel the Adventurer. When someone starts programming they piece together instructions in a specific order using something that a machine can read. Through the use of programming, students will develop an understanding of how a computer navigates instructions and order. Using a new character with a different puzzle objective will help students widen their scope of experience with sequencing and algorithms in programming.

Objectives

Students will be able to:

  • Order movement commands as sequential steps in a program.
  • Represent an algorithm as a computer program.
  • Develop problem solving and critical thinking skills by reviewing debugging practices.

Introduction

This lesson uses most of the same blocks from Course C, Stage 2 Programming in Maze and adds the ability to collect. Tell the students that this block will allow Laurel the Adventurer to pick up the treasure that she is standing over. This new block will be discussed more in the bridging activity.

Bridging Activity - Programming (10 min)

This activity will help bring the unplugged concepts from Real-Life Algorithms: Paper Airplanes into the online world that the students are moving into.

Previewing Online Puzzles as a Class

Pull a puzzle from the corresponding online stage. We recommend puzzle 7. Have students discuss a pattern that they think will get Laurel the Adventurer to collect all the treasure. Ask the students to share. See how many other students had the same answer!

Main Activity (30 min)

CSF Express Course 2018 - Website

Laurel the Adventurer is looking to collect as much treasure as she can. Instruct the students to traverse the puzzle to collect whatever they can. Some levels will require you to only pick up one piece of treasure, but others will require you to pick up every piece of treasure. Pay attention to the instructions to know what to do!

Wrap Up (5 - 10 min)

Journaling

Having students write about what they learned, why it’s useful, and how they feel about it can help solidify any knowledge they obtained today and build a review sheet for them to look to in the future.

Journal Prompts:

  • What was today’s lesson about?
  • How did you feel during today’s lesson?
  • Draw a maze that you might solve with the blocks you used today.
