A student notices similar patterns in different word problems. Which computational thinking pillar does this represent?
Scenario:
You are asked to test all the numbers from 1 through 20 to determine which ones are even. To do this, you create a step-by-step process:
Start with the number 1.
Divide the number by 2.
If the remainder is 0, label the number as even.
Move to the next number.
Repeat until you reach 20.
Question:
Which Computational Thinking strategy best describes this process?
Match the flowchart symbol with its meaning.

Scenario:
A simple program asks the user to choose heads or tails and enter their choice. The program then randomly generates either heads or tails. Next, the user’s choice is compared to the random result. If the two match, the program displays “You won”. If they do not match, the program displays “You lost.”
Select the correct flowchart from the options shown below that represents this program.
