Lesson 19: Determine the Concept

Overview

This series brings together concepts from previous lessons and gives students a chance to think critically about how they would solve each problem, but without telling them which concept to apply. Students will review basic algorithms, debugging, repeat loops, conditionals, while loops, and functions.

Purpose

It's important for students to remember that computer science provides plenty of opportunities to be creative. Every topic can be combined with another to make something bigger and better.

In this lesson, students will use previously learned concepts together, allowing for a "big picture" view of programming projects. This lesson will also bridge any gaps in understanding of when to use certain programming tools over others.

Objectives

Students will be able to:

  • Recognize which programming concept to use to solve a given problem.
  • Describe the different ways one could solve a given problem.

Introduction

This lesson is meant to review previous concepts by mixing them together.

Take this time to ask students to discuss their favorite parts of the course so far.

  • What did they like learning about? Why?
  • What did they not like learning about? Why not?
    • If it was too difficult, would they be interested in doing more activities to better understand those concepts?
  • What was something really cool they got to make?
  • What is something they hope to make with code someday? What kinds of programming tools might they use to make that?

This discussion should help the students get into the "bigger picture" framework that this lesson is trying to teach. Ask the students how they would pair certain programming tools together like:

  • Loops and conditionals
  • Functions and events

Because the concepts in this set of lessons are not explicitly given, students may face more frustration than usual. Make sure to walk around and do a "wellness check" on each student. If one student is struggling in some manner, pair them with another student in order to stimulate discussion between the two.

Wrap Up (15 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 do you feel about today's lesson?
  • What is your favorite thing you have learned in your coding class so far? Why? How have you used that in programs lately?
