To students, creativity and math seem completely incompatible. “Math is when I have to follow predefined steps and arrive at an exact answer! How could this be creative?”
three four ideas for quick math warmups that encourage students to use divergent, creative thinking to come up with unexpected, but correct, answers.
1. How Did We Get Here?
For our first creative math warmup, let’s begin at the end and ask students to come up with multiple paths that could have led us there.
For example, write a big “17” on the board and ask your students “how could we get to 17?”
Some simple paths include:
- 16 + 1
- 10 + 7
- 20 – 3
These are great staring points, but include some constraints, and kids will begin exploring even more creative ways to arrive at 17:
- take three steps (10 + 3 + 4, 8 × 2 – 1)
- use a decimal (34 × 0.5)
- incorporate a square root (√81 × 2 – 1)
There are literally an infinite number of ways to arrive at this one number, and this task encourages students to use their different math tools. Start each day with a new number. Try fractions, decimals, and negative numbers.
2. Who Doesn’t Belong?
A common math problem is to ask students to identify a pattern, given:
3, 6, 9, 12
But, using the same set of numbers, we can ask a different question: which number doesn’t belong?
Of course, there is no “right” answer. Students might say:
- 12 is the only two-digit number
- 3 is the only prime
- 9 is the only perfect square
- We can double 3 to get 6 and double 6 to get 12, but 9 doesn’t fit this pattern
Again, students with more math tools will be able to come up with more reasons to rule out certain numbers.

3. What’s the Question?
Inspired by Dan Meyer, show an intriguing image and ask kids “what question could we ask.” Make sure to tell them they don’t have to solve it, or they’ll be afraid to ask any difficult questions!
For example, show this image of a packed stadium.
What question could we ask, even if we don’t know how to answer it yet?
Possible questions include;
- how many people are at the stadium
- how much did people spend on tickets
- how many hot dogs were sold at this game
An awesome source of these types of images is Dan’s own 101QS.com, a site built around images with potential math applications.
4. Guess My Number
As a variation on “20 Questions,” allow the class to ask a certain number of questions to determine the number that’s “in your head.”
Questions might include:
- Is it odd or even?
- Positive or negative?
- Integer or non-integer?
- Rational or irrational?
- Greater than 10 or less than 10?
Of course, once they get the idea, students can choose their own numbers and work within groups to practice together, or make you guess their number.
Each of these warmups are quick and honor kids’ naturally creative thinking which is so commonly shut down during math periods.
