Here's what you get in this bundle:

1. Functions Lesson Pack with Notes & Practice

This jam-packed resource included "cheat sheets" that can be filled in as guided-notes or given to students as a reference. They cover the topics of identifying functions, function notation, and domain & range. Task cards and practice worksheets are included for extra practice.

2. Identifying Functions Practice PowerPoint

This works great as a no-prep formative assessment! With student white boards or a simple thumbs-up/thumbs-down, students can let you know whether they think each relation is a function or not.

3. Linear Functions Card Sort

This hands-on activity challenges students to look at graphs, mapping diagrams, tables, set of ordered pairs, and equations. They determine if each one is a function and if it's linear. This works great with groups or partners.

4. Self-checking Google Slides for Identifying Functions

Students can quiz themselves and get feedback with this digital activity! After each response, they are shown the correct answer and given feedback if they answer incorrectly.

5. 10-Question Assessment

In the bonus file, you'll find a printable test with 10 questions to see if your students understand functions. Answer key is included.
