This task could be put to good use in an instructional sequence designed to develop knowledge related to students' understanding of linear functions in contexts. Though students could work independently on the task, collaboration with peers is more likely to result in the exploration of a range of interpretations.

Unit: Area and Surface Area Lesson 10: Bases and Heights of Triangles
This lesson furthers students’ ability to identify and work with a base and height in a triangle in two ways:
By learning to draw (not just to recognize) a segment to show the corresponding height for any given base, and
By learning to choose appropriate base-height pairs to enable area calculations.
Students have seen that the area of a triangle can be determined in multiple ways. Using the base and height measurements and the formula is a handy approach, but because there are three possible pairs of bases and heights, some care is needed in identifying the right combination of measurements. Some base-height pairs may be more practical or efficient to use than others, so it helps to be strategic in choosing a side to use as a base.

The PFACS game engages students in playing the role of a music producer who must use data and computational thinking to promote their artist’s careers. “Data and Analysis” is one of five strands in the CS K-12 Framework — and it is a strand that readily bridges to mathematics and science content that you already teach. By giving students time to play the game and then having related classroom discussions, you can gain insight into your students’ progress in understanding these concepts.
This game does NOT require any coding skills nor knowledge of any programming language. It is about making choices using computational thinking concepts, not about writing code.
Beats Empire was designed for teachers:
In middle schools classrooms That integrate data science, computational thinking and related concepts For about an hour of use spread over 2-3 class periods Where students have access to any computer, laptop or desktop, with Chrome or Firefox browser (not recommended for tablets or phones). The key goals of Beats Empire are:
Students explore how their data skills addresses a real world challenge Students gain career awareness of attractive data science jobs Teachers increase their understanding of what students know and can do
The true, inspiring story of Beauty, the bald eagle, who was shot, …
The true, inspiring story of Beauty, the bald eagle, who was shot, rescued, and received a 3D-printed prosthetic beak. The resource includes a lesson plan/book card, a design challenge, and copy of a design thinking journal that provide guidance on using the book to inspire students' curiosity for design thinking. Maker Challenges: (1) Use paper and pencil to design a prosthetic body part for a human or animal. Then use tinkercad.com to create a prototype. Finally, use a 3D printer to print the prosthetic. (2) Have students research animals who use prosthetics. Then, improve the design in Tinkercad and 3D Print.
A document is included in the resources folder that lists the complete standards-alignment for this book activity.

This course covers a range of algebraic topics: Setting up and solving linear equations, graphing, finding linear relations, solving systems of equations, working with polynomials, factoring, working with rational and radical expressions, solving rational and radical equations, solving quadratic equations, and working with functions. More importantly, this course is intended to provide you with a solid foundation for the rest of your math courses. As such, emphasis will be placed on mathematical reasoning, not just memorizing procedures and formulas. There is enough content in this course to cover both beginning and intermediate college-level algebra.

Unit 3: Unit Rates and Percentages Lesson 13: Benchmark Percentages
The goal of this lesson is to help students understand the connection between benchmark percentages and common fractions (MP7). In these materials, we have identified 10%, 25%, 50%, and 75% as primary benchmark percentages and multiples of 10% as secondary benchmark percentages.
It is common to say that 25% = 1/4 or 10% = 1/10 . In these materials we avoid this usage and say rather that 25% of a quantity is 1/4 of that quantity, or that 10% of a quantity is 1/10 of that quantity.
This lesson builds on understanding of equivalent fractions, multiplying fractions, and dividing by unit fractions from grades 4 and 5.
