Oh, the sweet irony of living in a town that ships Christmas trees all over the nation (seriously, they helicopter them out by the bunch), yet I don’t have room for one in my house.
A few years ago, after seeing a few ideas of DIY space-saving Christmas trees on Pinterest, I was inspired to make my own (or should I say I was inspired to enlist my dad to carry out my vision?).
A while back I made a display for special right triangles, and realized I never shared the files! You can download the PDF and the editable Publisher files here! You’ll need to download the free font HVD Comic Serif Pro if you choose to edit the Publisher file yourself.
Here’s a picture of the pre-laminated pieces. I took a few pieces of the finished product on my walls in the classroom, but each one had a nasty glare from the laminated finish.
Throughout the year, I will be adding more justifications as they come along. The next batch that we will come across will be about segments. From there, we’ll talk about angles, congruence, similarity, and more!
Here’s what I’ve got so far! What justifications you most want to include in an edited list? I plan on using these primarily for two-column proofs in geometry.
