As a math teacher, you’re always on the lookout for fun and engaging ways to challenge your students and enhance their understanding of key concepts. One such innovative approach is integrating game-based learning into your lessons. This blog post will explore an exciting classroom activity that can help students grasp the importance of divisibility rules. This game is titled “Can You Win Over Half a Million Dollars?” ($550,000 to be precise).
Before delving into the details, gameplay instructions, and examples, let’s look at the overall structure and objective of this game.
Overview and Objectives

“Can You Win Over Half a Million Dollars?” is a math game designed for a classroom setting that tests students’ knowledge of divisibility rules. The students need to answer ten questions, each with multiple-choice or true/false options. The difficulty level gradually increases, challenging students to think critically and apply their knowledge as the game progresses.
The game not only reinforces the divisibility rules but also introduces an element of competition, encouraging students to strive for accuracy and speed. And the best part? No calculators allowed! This encourages students to fully engage with the math, relying on their mental arithmetic skills and understanding of divisibility rules.
The main objectives of this activity are:
- To strengthen students’ understanding of divisibility rules.
- To foster critical thinking and problem-solving skills.
- To promote healthy competition and active participation.
- To create a fun, interactive learning environment.
Gameplay Instructions

To initiate the game, each student receives an answer sheet. Teachers will read aloud ten questions related to divisibility rules, providing 1-2 minutes for students to answer each question. Students should write their answers clearly and legibly on the answer sheet.
The winning scheme of this game follows a ‘win-as-you-go’ pattern. With each correct answer, a student’s winnings increase. However, one wrong answer means they can no longer earn any more money. This progression adds a sense of risk and anticipation, as each question could dramatically impact the student’s virtual earnings.
Gameplay Scenarios

Here’s an example of the game flow with the initial four questions:
- Question 1: The number 1234 is divisible by which of these numbers? (a) 2; (b) 5; (c) 6
- Gameplay Scenario: Students will remember that a number is divisible by 2 if its last digit is even. Thus, the correct answer would be (a) 2.
- Question 2: All numbers that are divisible by 10 end in zero. (a) True; (b) False
- Gameplay Scenario: Students would recall that one of the fundamental divisibility rules is that any number ending in zero is divisible by 10. Hence, the correct answer is (a) True.
- Question 3: We know that the number 370 is divisible by 7 because it has a 7 in it. (a) True; (b) False
- Gameplay Scenario: This is a tricky question meant to address misconceptions about divisibility. Divisibility by 7 has a specific rule that doesn’t relate to having a 7 in the number. So, the correct answer is (b) False.
- Question 4: If the first number is divisible by 3 and the second number is divisible by 5, then the product of the two numbers is divisible by 15. (a) True; (b) False
- Gameplay Scenario: Students need to apply their understanding of the fact that the product of two numbers is divisible by the product of their divisors. So, the correct answer is (a) True.
As the game progresses, the complexity of the questions can increase to ensure students are continuously challenged and stimulated.
Accommodations and Modifications
While the game is a powerful tool for engaging students in learning divisibility rules, it’s essential to make accommodations and modifications for diverse learners.
- English Language Learners (ELL): For students who may struggle with language, simplify the language of the questions or provide translated versions.
- Learning Differences: For students with learning disabilities, consider extending the time limit for answering questions, providing a written copy of questions, or even allowing them to play in pairs or small groups.
- Advanced Learners: For gifted students or those who need an extra challenge, incorporate higher-level divisibility questions, such as questions involving larger numbers or complex combinations of divisibility rules.
These accommodations and modifications ensure that every student can participate fully in the game and gain valuable learning from it, regardless of their learning style or ability level.
Aligning with the Common Core State Standards (CCSS)
This game aligns well with various CCSS, especially in the domain of Numbers and Operations in Base Ten. Here are a few specific standards that this game can help students meet:
- 4.NBT.B.6: Students find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division.
- 5.NBT.B.6: Students find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division.
- 6.NS.B.2: Students fluently divide multi-digit numbers using the standard algorithm.
Incorporating game-based learning, like “Can You Win Over Half a Million Dollars?” into your math instruction, provides a powerful and engaging tool to help students solidify their understanding of key mathematical concepts.
