Validate a Business Idea: Student Activity and Template

Q: How can English learners take part in assumption testing?

Give sentence frames: "We believe ___. We will test it by ___. It passes if ___." Assign roles so English learners can run a hands-on test, such as a wash test or a tally sheet, while practicing the language of results. Numbers and pictures in each row let them show what they learned without long sentences.

Lesson Plan Overview

Every business plan is a stack of guesses. Students believe people want their product, will pay their price, and that they can make it. Real startups don't wait to find out; they test their riskiest assumptions first, as cheaply and quickly as possible. In this activity, teams write down the three beliefs their business depends on, design a small test for each, run it, and record what happened. It teaches a key entrepreneurial habit: being wrong early is cheap, being wrong late is expensive.

The three beliefs match three questions we ask of any idea, from our elevator pitch article: Would people use it? Can it make money? Can we actually build it? For the full method used by startups, see Validating Your Business Assumptions.

Before You Begin

Time needed: 30 minutes to plan, a few days to run the tests, 30 minutes to record results.
Good tests are small: a sign-up sheet, a fake "pre-order" button, five interviews, a homemade prototype, or a price poll. No spending required.
Safety: tests that involve selling or collecting information from people outside class should be approved by the teacher first.
Assessment: each test must have a clear pass/fail number decided before running it, and the "what we learned" column must include a decision: keep, change, or drop.

The T-Chart

QUESTION	WE BELIEVE… / HOW WE WILL TEST IT	WHAT WE LEARNED (EXAMPLE: TAGBACK)
Would people use it?	Students will put tags on their stuff. Test: give 20 free tags to one class; pass if 12 students use them within a week.	15 of 20 used them, mostly on water bottles. Keep.
Can it make money?	Parents will pay $6 for 10 tags. Test: post a pre-order form in the PTA newsletter; pass if 25 parents sign up.	Only 11 at $6, but 31 when we offered a $10 family pack of 25. Change the offer.
Can we build it?	We can print waterproof QR tags that survive the washer. Test: wash three sample tags five times.	Paper stickers failed; iron-on fabric labels passed. Change the material.

Reflection Prompt

Which result surprised your team most? What would have happened if you had skipped the test and gone straight to selling?

Student Instructions

Create a T-chart that tests the three biggest beliefs behind your business.

For each question (Would people use it? Can it make money? Can we build it?), write one thing your team believes.
Describe a small, cheap test for each belief and the number that means it passed.
Run your tests (get your teacher's approval first).
In the second column, write what happened and your decision: keep, change, or drop.
Illustrate each row, then save and submit your storyboard.

How to Run the Test Your Assumptions Activity in Storyboard That

Assign the T-chart template to teams

Assign the template from your Teacher Dashboard so each team works in one storyboard and everyone sees the same beliefs and results.

Have teams write beliefs and tests

For each question, teams write one belief, a small and cheap test, and the number that means the test passed.

Approve tests before teams run them

Review each plan and approve any test that involves selling or collecting information from people outside class.

Run the tests and record results

Teams run their tests over a few days, then fill in the second column with what happened and a keep, change, or drop decision.

Review and debrief

Check that each decision follows from its result, then have teams share their most surprising result with the class.

Frequently Asked Questions about the Test Your Assumptions Activity

How should I grade the Test Your Assumptions T-chart?

Score each of the three rows 0–4: one point each for a clear belief, a cheap test, a pass number set before testing, and a keep, change, or drop decision. That makes 12 points. TagBack's pricing row is the model: it failed at $6, so the team changed the offer instead of ignoring the result.

How long does it take to run the assumption tests?

Plan 30 minutes to write beliefs and tests, a few school days to run them, and 30 minutes to record results. Start early in the week so sign-up sheets, price polls, and prototype checks like TagBack's five-wash label test have time to finish before teams fill in the second column of the T-chart.

Can grades 6–8 test their business assumptions?

It is aimed at grades 9–12, but middle school teams can test one belief instead of three, usually "Would people use it?" A class poll or a handful of free samples, like TagBack's 20 free tags, is enough. High schoolers and DECA or FBLA teams should test all three beliefs and explain how each result changed their plan.

How can English learners take part in assumption testing?

Give sentence frames: "We believe ___. We will test it by ___. It passes if ___." Assign roles so English learners can run a hands-on test, such as a wash test or a tally sheet, while practicing the language of results. Numbers and pictures in each row let them show what they learned without long sentences.

What should students reflect on after testing their assumptions?

Ask which result surprised the team most, and what would have happened if they had started selling first. Discuss why the pass number has to be set before a test runs. Then ask which decision, keep, change, or drop, was hardest to make. Teams that dropped an idea should explain what they will test next.
