It's crazy to intend almost how much things tin alter over the course of didactics of a year. Last year, I was dreading teaching conic sections to my Algebra 2 students. When I took Algebra 2 inwards high school, in that place were actually solely 2 topics that gave me grief: matrices as well as conic sections. And, yesteryear grief, I only hateful that I had to really, really, actually operate at them. Math has ever came easily for me. Though, I did accept a actually terrible fourth dimension learning to say fourth dimension inwards the offset grade. I yet recall getting clock worksheets returned, covered inwards carmine ink.
I've been eagerly anticipating starting conic sections! This year, I've made only about changes to how I'm teaching conic sections. Oh, we're yet using the conic cards. I can't imagine teaching without them! But, instead of having the students purpose the reference cards inwards the deck, I accept created interactive notebook pages for my students to use. It's a beautiful, beautiful affair to scout my students purpose their notebooks.
This unit of measurement has been i where I've had to employ a lot of tough love. As much every bit possible, I desire students to bring out the patterns as well as relationships for themselves. So, the real offset solar daytime amongst the conic cards, I refused to hand my students whatever help. Instead, I directed them to page 63 inwards their notebooks. When they protested, I told them that I had organized faith inwards them as well as their mightiness to figure this out for themselves. I had only about real angry students that day. But, almost all of them accept eventually came around.
Even though I'm trying to survive less helpful, I've seat no restrictions on letting students attention other students. I dear watching these mini-tutoring sessions. Usually the conversations become a lot similar this:
Student 1: I'm never going to survive able to figure these out.
Student 2: Have you lot asked Ms. Hagan for help?
Student 1: No, she's only going to say me to await inwards my notebook for help.
Student 2: Well, where is your notebook? Why don't you lot at to the lowest degree opened upwards it up?
Student 2 unremarkably goes on to walk Student 1 through the procedure of matching upwards a yoke of cards. They reference the notebook page as well as explicate every pace of their idea process. I've learned as well as thence much to a greater extent than almost how much my students sympathise yesteryear listening to these tutoring sessions than if I had explicitly explained my solving procedure to the class. How many other times accept I cheated my students out of the chance to bring out things for themselves?
Another alter I accept made this yr is using Rebecka Peterson's Conic Sections Flow Chart. I downloaded it from her blog, as well as I was pleased to bring out it was already perfectly formatted to fit correct inwards our interactive notebooks! This photograph isn't the best, but this has been an amazing resources for my students.
Whenever somebody holds upwards a carte as well as asks, "Is this a circle?", I at in i lawsuit inquire them if they accept checked their menstruum chart. We become through the questions. Are both variables squared? Are the squared ters subtracted? Do the squared price accept dissimilar denominators?
Later this calendar week (hopefully), I volition survive posting the private pages I created for each dissimilar conic section.

Through the amazing community that is the #MTBoS, I was introduced to Cindy Johnson's conic cards. At first, my students were actually frustrated amongst the procedure of trying to agree upwards verbal descriptions, equations, as well as graphs. But, the to a greater extent than they talked through the matching procedure amongst their partner as well as the to a greater extent than nosotros practiced, the to a greater extent than my students (and I) started to autumn inwards dear amongst conic sections. As I helped my students await for as well as position patterns, I started to come across things I had never noticed every bit a high schoolhouse student.
