Lesson Plans
 Computing Needs All Voices

Students learn about a diverse group of programmers through a short film and a gallery walk of our Pioneers in Computing and Mathematics poster series, then consider the problem solving advantages that diverse teams foster.
 Introduction to Data Science

Students learn about Categorical and Quantitative data, are introduced to Tables by way of the Animals Dataset, and consider what questions can and cannot be answered with available data.
 Simple Data Types

Students begin to program, exploring how Numbers, Strings, Booleans and operations on those data types work in a programming language. Booleans offer an excellent opportunity for students to explore the meaning and realworld uses of inequalities.
 Contracts: Making Tables and Displays

Students learn about functions for sorting and counting data in tables, then are introduced to onevariable displays.
 Bar and Pie Charts

Students use data displays like bar and pie charts to create 1 and 2level groupings to visualize the distribution of categorical data.
 The Data Cycle

Students are introduced to the Data Cycle, a fourstep scaffold for getting an answer from a dataset  and then generating the next question! Students learn to identify  and ask  statistical questions, by comparing and contrasting them with other kinds of questions.
 Probability, Inference, and Sample Size

Students explore sampling and probability as a mechanism for detecting patterns. After exploring this in a binary system (flipping a coin), they consider the role of sampling as it applies to relationships in a dataset.
 Choosing Your Dataset

Students practice making a variety of chart types and then begin to investigate a real world dataset, which they will continue to work with for the remainder of the course.
 Histograms

Students are introduced to Histograms by comparing them to bar charts, learning to construct them by hand and in the programming environment.
 Visualizing the "Shape" of Data

Students explore the concept of "shape", using histograms to determine whether a dataset has skewness, and what the direction of the skewness means. They apply this knowledge to the Animals Dataset, and then to their own.
 Measures of Center

Students are introduced to mean, median and mode(s) and consider which of these measures of center best describes various quantitative data.
 Box Plots

Students are introduced to box plots, learn to evaluate the spread of a quantitative column, and deepen their perspective on shape by matching box plots to histogram.
 Standard Deviation

Students learn how standard deviation serves as Data Scientists' most common measure of "spread": how far all the values in a dataset tend to be from their mean. When we looked at box plots, we visualized spread based on range and interquartile range. Now we’ll return to histograms and picture the spread in terms of standard deviation.
 Scatter Plots

Students investigate scatter plots as a method of visualizing the relationship between two quantitative variables. In the programming environment, points on the scatter plot can be labelled with a third variable!
 Correlations

Students deepen their understanding of scatter plots, learning to describe and interpret direction and strength of linear relationships.
 Linear Regression

Students compute the “line of best fit” using the function for linear regression, and summarize linear relationships in a dataset.
 Ethics, Privacy, and Bias

Students consider ethical issues and privacy in the context of data science.
 Collecting Data

Students learn about the importance of careful data collection, by confronting a "dirty" dataset. They then design a simple survey of their own, gather their data, and import it into Pyret
 Row and Column Lookups

Students learn how to extract individual rows from a table, and columns from a row.
 Functions Make Life Easier!

Students discover that they can make their own functions.
 Functions: Contracts, Examples & Definitions

Students 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 with the Design Recipe

Students are introduced to the Design Recipe as a scaffold for breaking down word problems into smaller steps. They apply the Design Recipe to fixing a file that launches a rocket!
 Table Functions: Bringing it all Together

Students use the Design Recipe to define functions that consume rows, developing a structured approach to answering questions by transforming tables.
 Advanced Displays

Defining functions allows data scientists to create advanced data displays, which expose deeper insight into a dataset. This motivates students to define their own functions and deepen their analysis.
 Filtering and Building

Students learn about functions that work with tables, allowing them to filter and build columns
 Composing Table Operations

Students learn how to compose functions that operate on tables.
 Grouped Samples

Students practice creating grouped samples (nonrandom subsets) and think about why it might sometimes be useful to answer questions about a dataset through the lens of one group or another.
 Checking Your Work

Students consider the concept of trust and testing — how do we know if a particular analysis is trustworthy?
 Threats to Validity

Students consider possible threats to the validity of their analysis.
Student Workbooks
Sometimes, the best place for students to get real thinking done is away from the keyboard! Our lesson plans are tightly integrated with a detailed Student Workbook, allowing for paperandpencil practice and activities that don’t require a computer. That’s why we provide a free PDF of the core workbook, as well as a link to the book with every optional exercise included.
Of course, we understand that printing them yourself can be expensive!
Teaching Remotely?
If you’re teaching remotely, we’ve assembed an Implementation Notes page that makes specific recommendations for inperson v. remote instruction.
Other Resources
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.

Contracts Reference — Complete studentfacing documentation for all the functions used in these lessons (also printed in the back of the student workbook).

Glossary — A list of vocabulary words used in this pathway. We also provide a bilingual glossary, which defines all vocabulary words across our lessons in English and Spanish.

Standards Alignment — Find out how our materials align with National and State Standards, as well as some of the most commonly used math textbooks.

TeacherOnly Resources — We also offer several teachersonly materials, including an answer key to the student workbook, keys to all the exercises, and pre and posttests 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 uptodate 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.
