Day 2 of #MTBoSBlaugust!!!

This unit will focus again on what’s in my Interactive Notebook, but there is a proof activity I found from All Things Algebra. Other class activities are done depending on the needs of my students. I’m always chainring things, so who knows if theirs is how my unit will look this year!

The unit begins with a triangle sum activity I found on Math by Tori‘s site. Here are pictures including a proof.

They practice this with a worksheet from Mrs. Newell‘s page and one I created.

This is followed up by Exterior Angle Theorem which uses similar activities from the same sites.

Is it a triangle and Triangle Inequality activities are next. Students use snap together sticks (AngLegs) and this worksheet I think I found on Misscalcul8’s page a while ago to investigate what makes a triangle and I sum the activities up in notes from Mrs. Newell.

Finally, we get to congruent triangles, starting with a review of how we know things are congruent… the spacing may need to be adjusted.

Many activities to reinforce the shortcuts. Notes from Mrs. Newell

A cut and paste activity from TpT

And practice

Finally, proofs! Mrs. E and Mrs. Newell have a lot of proof tips for students on their sites.

And CPCTC

Thanks for reading!
