Fundraiser Check Answer Key

This worksheet uses fundraising situations to help students decide whether each plan is proportional or non-proportional. The examples include plans where students earn a fixed amount per item or activity, as well as plans that begin with a donation or contribution before the regular earnings start. That makes the worksheet especially useful because students can connect the idea of proportionality to money, goals, and fundraising events.

For a parent, the easiest question is: “Does the fundraiser start at $0?” If the student earns only a fixed amount per item and there is no starting donation, the relationship is proportional. If the fundraiser begins with money already collected, then the relationship is non-proportional.

Learning Goals

• Classify Real-World Relationships: Students decide whether fundraising plans are proportional.
• Identify Starting Amounts: Learners notice initial donations and contributions.
• Recognize Constant Rates: Students identify earnings per item, car, lap, ticket, or snack.
• Connect Context to Algebra: Learners understand how a starting amount affects the relationship.
• Build Financial Math Reasoning: Students apply proportional thinking to realistic money situations.

Parent-Friendly Explanation

For example:

The art club earns $4 for every calendar sold, with no starting donation.

At 0 calendars sold, the club earns $0.

That is Proportional.

But:

A local store donates $50 first, then adds $2 for every coupon book sold.

At 0 coupon books, the fundraiser already has $50.

That is Non-Proportional.

Why This Worksheet Helps

• Makes Proportionality Practical: Students see the concept in a money context.
• Reinforces the Zero-Start Rule: Initial donations make the distinction easy to see.
• Strengthens Word-Problem Reading: Learners must identify the rate and the starting amount.
• Prepares for Equations: These situations naturally lead to y = kx or y = mx + b.
• Builds Financial Awareness: Students connect math with fundraising and earnings.

Classroom & Home Use

• Great for Real-World Lessons: Fundraising is an easy context for proportional relationships.
• Helpful for Parents: Adults can ask, “Is there money at the beginning before anything is sold?”
• Useful for Small Groups: Students can explain why a plan is proportional or not.
• Good for Assessment: Teachers can see whether students understand starting values in context.
• Strong for Homeschooling: Families can create similar examples using chores, sales, or savings.

The main value of this worksheet is that it helps students see that a constant rate is not the only thing that matters. The relationship also has to start at zero to be proportional. For parents, the best coaching question is: “Before anything happens, is the amount already above zero?”
