Bootstrap:A deep dive into an
engaging resource for math and cs educatorsCan computer
programming help students learn algebra?
Algebra and Programming. At Scale.
Start with learning : what and why?

f(x) = x+2processobject
6 = x+26 = ☐+2☐ = 4+2
Understand students’ challenges
Make representations of functions concrete and connected
Know Your History
If you’re teaching algebra, make sure your language is actually algebraic
x = 1x = x + 2
Be Authentic

Arithmetic is just function composition

The Design RecipeConnecting functional representations
“A plane rises 1.5 meters for every one it travels forward. Write a function that describes its height as a function of time”
How would you think of it as a mapping between domain and range?
Could you construct a table? A formula? A graph?
Let’s see this in code…

Align to Standards, Gather Data
• Aligned to TEKS standards for mathematics
• Using pre/post tests with questions from state math exams, Bootstrap students significantly outperformed a comparison group taking a regular math class.
Implementation• Software: Free and in the cloud. If you have a browser, you’re done!
• Materials: All lesson plans, handouts, workbooks, etc. are available for free, and aligned to Common Core Standards for Mathematics.
• Professional Development: We partner with districts, schools and after school programs in states across the US.

Algebra is the gateway to STEM
Make functions concrete and connected
Start with an algebraic language
Aim for transfer
Start with learning
What is the difference between Programming and Coding?
