- "A function relates an input to an output." is just the beginning of the description provided here. Scroll through the whole page to see examples and non-examples.
Developmental Math - An Open Program
- Click "View Course Now" and fill in your information under "See For Yourself!". Unit 17 is the unit that may help Adult Education Teachers review Functions.
Dan Meyer's Three Acts Spreadsheet
- Check out the huge variety of other Three Acts . You'll find Leaky Faucet, the Three Acts we looked at together, on this list.
Mathematics Assessment Project's Lines and Linear Equations
- This is the lesson description, materials, and PowerPoint resource we used in small groups to match graphs, equations and pictures of the flowing liquid. Everything you need to use this with your class can be found through this link.
Using a Lottery to See the Uniqueness of Functional Relationships
- Here's an idea for introducing Functions. You can view this classroom video from the Teaching Channel without signing up. Registration is free and it will allow you to download the resources you see.
Conjecturing about Functions
- Another video from The Teaching Channel. This 8th grade teacher talks about how she makes use of Growing Patterns to help students reason about Functions. Materials to teach the lesson are included if you sign in (free registration).
Slope and House Construction
- Here's a real-life situation where slope is actually a slant. "In this video from Annenberg Learner’s Learning Math, carpenter Norm Abram of This Old House illustrates the concept of slope and relationships in house construction. The accompanying classroom activity helps students develop meaning for slope by building a slide, discussing slope in daily life, and understanding slope as a ratio of height/length. Students also learn about a career that uses the principles of slope and, as an extension, gather data that might be of use in a future lesson on slope as proportion.
Graph a Line from an Equation
- This interactive equation to graph program gives lots of explanation to wrong answers, which students can learn from. It does focus on procedure, but used with other lessons, it is a good supplement. The style is similar to the way students will answer questions on the 2014 GED test.
Equipped for the Future (EFF) Line 'Em Up! Mini Course
- "This is a 8 hour online mini-course that is designed especially for adult education practitioners who wish to build a stronger foundation in mathematics for their students and themselves. Intended for teachers, this course is designed to assist you to:
- Be comfortable introducing concepts like functions, linear equations, and the coordinate plane to adult learners at ALL educational levels
- Be able to help learners describe functions using examples from their own experiences
- Gain some strategies to assist your students in:
- Making connections among different representations of a function, particularly in-out tables, graphs, and equations
- Deriving equations from patterns in in-out tables and graphs"
