Quiz Game with Positive and Negative Numbers
Students are tasked with creating a quiz game that challenges their understanding of positive and negative integers. The teacher begins by introducing real-world scenarios where these numbers are commonly used, like temperature changes and financial transactions. To make the activity more engaging and computational, students are encouraged to think of the quiz game as a scoring algorithm that processes player inputs (answers) and adjusts scores accordingly, reinforcing the concept of state changes. The students work in small groups to define clear rules for how the algorithm handles positive and negative scores, ensuring the system is consistent and fair.
As the groups create their quiz questions on index cards, the teacher circulates, prompting them to think computationally about the game's logic. She asks, “What happens when a score reaches zero? How does your game handle this?” One group decides to implement a rule where reaching zero freezes the player out for a turn, drawing a parallel to a bank account that can’t go below zero without triggering a penalty. This leads to a class-wide discussion on designing systems that handle such conditions, encouraging students to think algorithmically about how their quiz game models real-world scenarios like bank overdrafts or being below sea level. The lesson concludes with students sharing their score tracking "systems" and explaining the algorithms they used to ensure correct handling of positive and negative integers.
Objective:
Students will practice using positive and negative numbers to describe quantities by creating and playing a quiz game. They will build an algorithm for scorekeeping that includes conditionals to determine how their score changes based on correct or incorrect answers. Through this process, they will explore how integers interact and apply this understanding to real-world contexts.
Materials Needed:
Index cards
markers
chart paper
Steps:
Introduction:
Begin by discussing positive and negative numbers and how they apply to everyday situations like temperatures above and below zero or bank transactions with credits and debits.
Explain that students will create a quiz game where their score will increase or decrease based on whether their answers are correct or incorrect. Emphasize that they will design an algorithm for scorekeeping that includes conditionals—rules that dictate what happens to their score in different scenarios.
Group Activity:
Divide students into small groups.
Each group will write math questions on index cards and design a scoring algorithm. The score starts at zero, increasing by 1 point for correct answers (+1) and decreasing by 1 point for incorrect answers (-1).
Students must include conditionals such as, "If a player’s score is zero and they answer incorrectly, the score remains zero."
Encourage students to think about other conditions, like what happens when scores become negative or when they return to zero.
Testing and Refining:
As students play the quiz, they apply their scoring algorithms and track how scores change using positive and negative integers.
Guide them in discussing and refining their conditionals, such as what happens when their score goes negative or hits specific thresholds. For example, students may decide that a score of -5 triggers a special condition where the player needs two consecutive correct answers to get back to zero.
Encourage students to draw connections between these scenarios and real-life examples like going into debt or being below sea level.
Discussion:
After the game, have each group share how their algorithm worked, focusing on how they handled different conditions, such as what happens when a score reaches zero or goes negative.
Discuss real-world parallels, asking questions like, "How is having a negative score similar to owing money in a bank account?" or "What kind of condition might you add if a score becomes too high or low?"
Equity and Access:
Provide prepared quiz questions and score tracking sheets for students who need additional support. Allow students to collaborate on scoring to ensure that all students understand how positive and negative numbers work.
Real-World Connection:
Relate this lesson to real-world scenarios like financial literacy, where people must manage positive and negative balances, and scientific contexts like measuring elevation.
CS Practice(s):
Recognizing and Defining Computational Problems: Students explore how positive and negative numbers are used to represent quantities.
Communicating About Computing: Students discuss their quiz results and reflect on how scores change based on positive or negative integers.

Quiz Game Coding with Variables
Students sit in front of their computers, coding a quiz game in Scratch. Each student creates a “quizScore” variable, initialized at zero, which adjusts based on whether the player answers questions correctly or incorrectly. As they test their games, one group realizes their score goes into negative numbers after too many wrong answers and decides to add code that plays a special sound effect when the score drops below zero. The teacher walks around the room, guiding students to think about how the concept of positive and negative numbers relates to real-world applications, like temperature or money.
After completing their games, students present their quiz games to the class, discussing how the variables worked to keep track of their score.
Objective:
Students will use Scratch, Microsoft MakeCode, App Lab, or another coding platform to create a quiz game that utilizes positive and negative integers to represent scores, reinforcing their understanding of variables and how integers can describe quantities in real-world contexts.
Materials Needed:
Computers or tablets
Optional: Pre-made coding templates for quiz games
Steps:
Introduction:
Students review positive and negative numbers, providing examples in real life, such as temperatures above/below zero or financial transactions.
Explain that they will be creating a quiz game in a coding platform where scores can increase or decrease depending on whether the player answers correctly or incorrectly.
Group Activity:
In pairs, students will use a coding platform to create a quiz game. They will define a “quizScore” variable, which starts at zero, and write code that increases the score by one for correct answers and decreases it by one for incorrect answers.
Encourage them to explore how the score can become a negative number and what that means in the context of the game.
Creating and Coding:
Guide students through coding their quiz games. Help them set up variables for tracking the score and program the game to change the score based on player input.
Encourage creativity by allowing them to add sounds or visual effects when the score reaches certain values, such as negative numbers.
Testing and Refining:
Students will test their quiz games, ensuring that the score variable updates correctly for both correct and incorrect answers.
They will refine their code based on test results, making adjustments to the score system as needed.
Presentation and Discussion:
Students will present their quiz games to the class, explaining how they used the variable to track scores and how positive and negative numbers influenced gameplay.
Lead a class discussion on how these coding concepts relate to real-world scenarios, like balancing bank accounts or monitoring temperature changes.
Equity and Access:
Provide pre-made coding templates with partially completed quiz games for students who need extra guidance. Pair students with different coding skill levels to ensure collaboration and peer support.
Real-World Application:
Connect the lesson to everyday situations where positive and negative numbers are important, such as monitoring temperature, managing money, or keeping track of sports scores.
CS Practice(s):
Creating Computational Artifacts: Students code a quiz game using variables to store and manipulate data.
Testing and Refining Computational Artifacts: Students test and refine their quiz game by analyzing how changes to the variables affect the game’s functionality.
