Today we practiced performing operations on functions and compositions of functions. I've created flashcards (all of the speed dating cards) on this website. Simply click on the link and then choose "flashcards" at the top left. In order to complete the flashcards, you need to know the functions. They are listed below:
Today we discussed composition of functions - relating it to an input going through one function machine, and then that output becoming the input of a second function machine. We then did six examples together in class, and finally, students worked on 10 practice problems. I heard a lot of good conversation from students while you all were working! Anything you didn't finish is homework! Here are the notes: A blank copy of the foldable can be found here and the homework that will go on page 13 is embedded below. Have a wonderful weekend! Today we discussed operations with functions and evaluating functions. We created a foldable (p. 12) with four examples - one each of a sum, difference, product, and quotient of two functions. Then, you worked with a partner to play a row game. Each of you were responsible for answering 9 questions, which should match the answers to the 9 (different) questions that your partner answered. Homework tonight it to complete any row game problems that you did not finish in class. We will begin tomorrow by spending some time comparing with partners.
We took our first quiz today! You'll get them back either Friday or Monday. I can't move faster than that because I am, in fact, not a wizard.
Tomorrow you have a quiz on the review topics so far, and Section 1-1 (Domain and Range). The following topics will be assessed:
We started today by going over the homework (completing the practice cards). A photo of the answer key is below. Make sure that your answers are correct so that when you study for the QUIZ ON WEDNESDAY you are studying from the correct material! Lots of you asked really great clarifying questions about domain and range, and about set and interval notation as well. If you have any further questions before the quiz, please come to COACH CLASS TOMORROW! I can't wait to see you there! :) We then finished up our foldable on finding the domain when you're given an equation. The rest of the foldable notes are here: Your homework tonight is to complete the new practice cards, which will live in bliss with your domain/range cards in their teeny adorable envelope on page 9 of your ISN. I've embedded the cards below if you need them. Make sure to label them from A-L (going across) since I was a silly head and forgot to label them before printing them out for you! We began the day by reviewing the homework and practicing some more with set and interval notation. We then jumped into a new foldable, in which we show how to find the domain algebraically. We looked at finding the domain of square root functions, and we started rational functions. On Monday, we'll finish up by talking about the domain of polynomials. The foldable was created from an 8.5"x8.5" square which we folded up by folding in all the corners to the middle. The inside *so far* is below: And here is a photo of the lovely outside of our foldable: Homework is to complete ALL of the domain/range practice cards! Don't forget: there's a quiz coming up next Wednesday on review topics and Chapter 1-1. So, basically everything in your ISN so far.
We began the day by practicing using our domain/range machine. Here we are practicing domain: And then, of course, the range: We then created a foldable on set notation and interval notation, so that we have a common mathematical language for describing the domain and range. We folded a 8.5" x 6.5" paper in half and cut two doors to make this mini two-door foldable to put right under our domain/range practice card envelope on page 9 of our ISNs.. And here's the inside! Homework was to write out the domain and range in both set and interval notation on the back of practice cards B, C, D, and E!
We had a shorter than usual period today, so we used our time creating an envelope for some practice cards, and constructing a Domain/Range machine. The envelope template can be found here, at this math teacher's blog. I printed ours out at 65% the original size, which made it perfect to fit our practice cards! Today we started Pre Calculus for realsies! We started by watching a very scholarly and historically accurate "meat-a-morphosis" video about functions, domain, and range. My apologies to any vegetarians. We then created a foldable (page 8) about relations and functions, as well as an introduction to domain and range. This is not a foldable that I invented - the file for it can be found at this lovely math teacher's blog. We then cut out and sorted some graphs, tables, lists, and mapping diagrams, and sorted them into "function" or "not a function" on page 7. |
