### Description

This flexible resource includes two products, **Introduction to Matrices** and **Determinants and Multiplicative Inverses of Matrices**. It** **allows students to either build interactive math notebooks with guided notes (keys included) and foldable activities OR use the included presentation handouts (keys included) with the PowerPoint presentation for focused instruction. Quick checks for understanding (keys included) help to determine how well your students understand the material as you go. Choose what works best for your class and modify to make the content fit your needs. Notes are designed to clearly present the topics and reach all types of learners.

The zip file includes BOTH editable, plain-font resources and ready-to-print, non-editable PDFs. Suggested use guides are included.

**Interactive Math Notebook FORMAT** – Includes 3 parts: guided notes, foldable activities, and quick checks for understanding. Piece the components together and students can create their own “math textbook” in a math journal.

**Presentation Sheets FORMAT** – Include 2 parts: guided notes and quick checks for understanding. They are organized in the same order as the included PowerPoint and are designed to print and present. The quick checks can be cut off the bottom of the note sheets and turned in as an assessment tool.

**Presentation** – Plain-font, no frills, PowerPoint presentation that you can use to present content to students. Slides have blank, student note templates followed by filled in teacher keys. Modify the editable presentation to best fit your needs.
