Product Description
Are you having trouble getting your students to take effective notes during math lessons? Are you looking for quick activities that can be completed in a math journal or at the end of a lesson as a check for understanding? If so, these activities are for you.

This product contains two separate components: scaffolded notes and interactive notebook activities.

These math journal and/or note-taking activities introduce geometric proofs to geometry students. They can be used for introduction of topics or to reflect/review what you have covered in class discussion. The problems listed in this activity packet build nicely on each other if introduced in the order that they appear. Our students enjoy filling them out and organizing them in their math journals so that they can refer back to them throughout the year. These activities are a great way to promote writing in math. Keys for scaffolded notes are included for reference.

Scaffolded Note Sheets with Sample Teacher Keys are included for the following topics:

How to earn TPT Credits:
"Earn TpT Credits for purchases on TpT. You get one TpT Credit for every $ you spend on TpT. Thing is, you only get the Credits after you Provide Feedback -- both a fair rating and a fair comment -- on the items that you purchase. We will round up for you, too! If you provide fair feedback on a $4.75 item, you will earn 5 credits. Every 100 Credits is worth $5 that you can apply towards future TpT purchases, but there is no need to wait until you have 100 to redeem them. 50 credits is worth $2.50, for example."--TPT Credits Page
