Grade 3 CT: If/Then Conditionals • Day 2

Grade 3 Computational Thinker If / Then Conditionals

DAY 2

Overview

Today I will continue learning how to solve puzzles using loops and conditional statements. I will translate spoken conditional statements into a program.

KEY VOCABULARY

Directions: Hover your cursor over the vocabulary word below to see the definition.

Motivation

STEP 1.

  Directions: Look at the following puzzle from Code.org.  Think about what you just learned about conditionals and the questions provided as you examine the puzzle.

Screenshot of Online Puzzle, Bee is two blocks away to the right from a cloud with a ? mark.

Questions to Consider

  • Do we know what is under the cloud?
  • If there is a flower under the cloud, what should the bee do?
  • If there is a honeycomb under the cloud, what should the bee do? 
  • How might be write these conditional statements using code?

Lesson

STEP 2.

  Directions: Select the play button to begin Conditionals: If Statements Links to an external site.. As you view this video, think about the code for the If Statement and how you can apply it to the puzzle above.

STEP 3.

  Directions: Review the Code.org Activity Tutorial - Google Slide (Links to an external site.).  Then follow the steps below to complete the Code.org If/Else Conditionals Maze activity.  You may not finish all of the steps in the activity today.  

 

 

 

Activity: If/Else with Bee

STEP 4.

Directions: Follow the directions below to complete the If/Else with Bee Activity to check your understanding of conditionals.

  1. Open the If/Else with Bee Code.org activity Links to an external site. in a new tab. Let's review Puzzle 2 together.
  2. Complete the practice and challenge puzzles 3-13. We have completed puzzles 1 and 2 during our lesson. You can review them if needed.
  3. The progress bar at the top of the page will keep track of which puzzle you are currently working on.  The shapes will turn green when you have completed that puzzle.Screenshot of Lesson 14: If/Else with Bee progress bar. Puzzle 3 is indicated with a white circle.
  4. The goal for each puzzle is across the top.  Move the code blocks around in the workspace to create the code needed to complete the goal.  Select Run to check your work.
  5. If your code is incorrect, try again.  Once your code is correct, select Continue to move on to the next puzzle in the task.Screenshot of popup window "Congratulations! You completed Puzzle 3.
  6. Continue working until all 13 puzzles are completed. 

Have fun coding!

 

Quick Check

STEP 5.

Directions: Take a look at the puzzle below.  In the puzzle the cloud is blocking the an unknown item. We don't know what is under the cloud. We can use Conditional Statements to tell our Bee want to do when he reaches this mystery item.

  • IF there is a flower under the cloud, THEN the bee should collect nectar one time. 
  • IF there is not a flower under the cloud, THEN the bee should not do anything.

Screenshot of an online puzzle. Bee is three blocks away to the left from a cloud with a ? mark.

 

 

Now take a look at the following code for this puzzle.  Based on this code, what do you think will happen after you select "Run"? Select your answer below.
