Lesson Plan

Course: Dragon Spells
Lesson 3: Deja Vu
Number of Levels: 6
Time: 30+ mins

Introduction

In this lesson, students are introduced to loops. A loop is a set of code that gets repeated a certain number of times or until a certain condition is met. Loops allow programmers to use reduce the amount of code that they have to write. To complete the puzzles, students will need to look for a repeating pattern that can be used to reach the pile of treasure. That repeating pattern will be what they place inside the loop code block.

New Code Blocks

  • : Repeat the code inside this loop a specified number of times.

Vocabulary

  • Loop: An action that repeats one or more commands over and over
  • Counting loop: A loop that repeats one or more commands a specific number of times
  • Parameter: An extra, specified piece of information that's used with functions
  • Pattern: Something that repeats

Objectives

Students will...
  • Apply loops and sequencing logic to solve puzzles
  • Identify patterns in code sequences
  • Use counting loops with numerical parameters

Materials

  • iPads (with installed Tynker app), computers, or laptops

Warm-Up (5 minutes)

Inform students that a "repeat" loop repeats code inside the loop for a specified number of times. Model an example of a "repeat" loop: For example, walk forward three times. Next, ask students:
  • What was the repeated action (Answer: walking forward)
  • How many times was the action repeated (Answer: 3 times)

Pair up students and ask them to create their own example of a "repeat" loop. Optional: Encourage students to model their example to their classmates. Can the other teams identify the repeated action and how many times it repeats?

Activities (30 minutes)

Facilitate as students complete all Deja Vu modules:
Deja Vu
  • Inform students that this lesson has 6 levels that they need to complete.
  • Level 1 introduces the "repeat" code block, which makes the character do the same thing a specific number of times. Give a hint: Ask students to count the number of spaces in front of their character (Answer: 5). Next, ask them to use a "repeat" code block. Emphasize to students that the value of the "repeat" block is set to 5 because the dragon has to walk 5 times to reach the treasure. Make sure students place the code block inside the repeat.
  • Point out to students that in level 2, the value of the “repeat” block is set to the incorrect value of "5." Tell students to count the spaces and change the “repeat” block to the correct value of "3." Make sure students understand how to change the parameter of the "repeat" block: Tap the value (e.g., 5). Next, select a different value (e.g., 7).
  • When students get to level 3, remind them that they need to use an “eat” block when their dragon stands one place in front of the bug. Also point out that they need to add a “walk” and “blast” code block inside the “repeat” loop. Students will need to add code before and after this loop. Any code outside the repeat block won’t be repeated.
  • Students can solve level 4 by placing 1 "jump" and 1 "turn around" block inside the loop.
  • Are students struggling with puzzles 5-6? Ask them to write down the steps the character needs to perform, and identify the pattern before using any code blocks.

Extended Activities (10 minutes)

Discussion
Ask your students…
  • True or false: What are some benefits of using a "repeat" loop in your code? (Example: Reduces the amount of code you have to write)
  • What are some strategies you use to identify "repeat" loops? (Answers will vary)
  • How would you describe "loops" to someone who hasn't used them before? (Answers will vary)
