- Simple Data Types
Students begin to program, explorings how Numbers, Strings, Booleans and operations on those data types work in this programming language.
Students learn how to apply Functions in the programming environment and interpret the information contained in Contracts: Name, Domain and Range. Image-producing functions provide an engaging context for this exploration.
- Function Composition
Students learn to combine image transformation functions as well as to describe the order of operations involved in algebraic function compositions such as f(g(h(x))) using Circles of Evaluation.
- Defining Values
Students learn to improve readability, performance and maintanability of code by defining values that repeat in code, just as we would define variables in math.
- Making Flags
Students recreate images of flags of varying complexity by transforming and composing image functions and applying their knowledge of ratios and coordinates to scale and position the shapes precisely.
- Defining Functions
Students discover that they can make their own functions, and learn to connect function descriptions across three representations: Contracts (a mapping between Domain and Range), Examples (a list of discrete inputs and outputs), and Definitions (symbolic).
- Solving Word Problems
Students are introduced to the Design Recipe as a scaffold for breaking down word problems into chunks that will support them in writing code.
- Introduction to Data Structures
Students encounter Data Structures in the context of using coordinates to model 2D animation. They explore constructors and fields, creating a "digital bakery" using structures to model cakes.
- Structures, Reactors, and Animations
Students implement animation using a modified Model-View-Controller paradigm called Reactors. Using a data structure to represent the position of an object, they write
draw-statefunctions to draw single frame from instances of that structure and
next-state-tickfunctions to generate new instances from previous ones. They learn how to use Reactors to combine their structure and functions into a complete animation.
- Functions That Ask Questions
Students are introduced to if-then-else expressions, writing conditionals that deal with simple types (Numbers, Strings, Booleans, etc) and data structures of their own to implement a more complex animation.
- Key Events
Students are introduced to key events, and use if-then-else expressions to write a key-event handler that moves an image left and right as part of an interactive animation.
This lesson focuses on code quality. Starting from a working program, students refactor the code to be more readable, writing helper functions thinking structurally about a complex program.
- Your Own Drawing Functions
This lesson removes earlier scaffolding from working with Reactors, having students brainstorm an original animation of their own and implement it from start-to-finish. This requires them to plan out what kind of data structure they will need, and how it will be drawn and updated.
- Build Your Own Animation
Students create a game of their own design using what they have learned so far.
- Adding Collisions
Students use the distance formula and their data structures to determine when two or more characters in their games have collided. They extend their
updatehandlers to generate a new structure that represents the game after a collision has occurred.
Students extend the data structure that represents their game to include a score, then modify their helper functions and event handlers to update and display that score.
- Adding Levels
Students parameterize other parts of their game, so that the experience changes as the score increases. This track delves deeper into conditionals and abstraction, offering students a chance to customize their games further while applying those concepts.
- Making Pong
Students use the Animation Design Worksheet to decompose a 2-player game of Pong, and implement it as a Reactor-based program.
- Going Deeper: Nested Structures
Students refactor code from a simple animation to include structures within structures, and see how to use nested structures in their own games and animations to manage complexity.
- Feature: Timers
Students parameterize other parts of their game, so that the experience changes as a new data field, a timer, changes. This track delves deeper into conditionals and abstraction, offering students two possible uses for a timer feature, and a chance to customize their games further while applying those concepts.

Ordering Student Workbooks?
While we give our workbooks away as a PDF, we understand that printing them yourself can be expensive! You can purchase beautifully-bound copies of the student workbook from Lulu.com. Click here to order.
If you’re teaching remotely, we’ve assembed an Implementation Notes page that makes specific recommendations for in-person v. remote instruction.
Of course, there’s more to a curriculum than software and lesson plans! We also provide a number of resources to educators, including standards alignment, a complete student workbook, an answer key for the programming exercises and a forum where they can ask questions and share ideas.
Glossary — A list of vocabulary words used in this pathway.
Standards Alignment — Find out how our materials align with National and State Standards, as well as some of the most commonly used math textbooks.
Workbook — Sometimes, the best way for students to get real thinking done is to step away from the keyboard! Our lesson plans are tightly integrated with the Student Workbook, allowing for paper-and-pencil practice and activities that don’t require a computer.
Teacher-Only Resources — We also offer several teachers-only materials, including an answer key to the student workbook, keys to all the exercises, and pre- and post-tests for teachers who are participating in our research study. For access to these materials, please fill out the password request form. We’ll get back to you soon with the necessary login information.
Online Community (Discourse) — Want to be kept up-to-date about Bootstrap events, workshops, and curricular changes? Want to ask a question or pose a lesson idea for other Bootstrap teachers? These forums are the place to do it.
