If you did not watch the video from yesterday’s post please do so tonight. IT is not long at all. Less than 5 minutes.
Today we worked on constructing a formula for finding the area of a trapezoid by doing an inquiry lab. Students used their prior knowledge about parallelograms and triangles to come up with a formula and tomorrow they will put that formula to use. The homework is verrrryyyyy similar to what we did in class today. See below for the notes if you did not finish in class.
Textbook pg. 595 & 596 Only Investigations 1 and 2. DO NOT do Investigation 3.
CAPS #18 odds only. I noticed half of you are not looking up the answers to your CAPS problem when you work on them at home. There are websites you can google that will compute fractions and mixed numbers. Google is your friend 🙂
Today we reviewed our 2 lessons from last week: Area of Rectangles & Area of Triangles.
Students signed a calculator contract before starting on the day’s lesson. The contract stated students must show work for all problems in order to use a calculator in class. The statement can be found below:
Feel free to start bringing your 4 function calculators to class.
Students numbered and set up their Table of Contents in their new MSG. Any students who did not have their MSG, received a signature on the blue card in their agenda. Agendas will be redeemed for all students who have their MSG before Friday.
HW: pg. 591 #1-3 and #6. Show all work to receive credit.
CAPS #16. Work problems on a separate sheet of paper and check answers with an online calculator. CAPS 16 problems are listed below:
Today we worked on finding the area of triangles by using the information we learned about triangles. We discovered after cutting parallelograms and rectangles in half, we have 2 perfectly congruent (equal) triangles.
Therefore the area of a triangle is always half of a parallelogram.
Here are the finalized notes from today’s Area of a Triangle Practice (5th period did not get to finish copying)
Here is your hw answers from Thursday night. Please check over. Remember finding perimeter is just adding up all the sides of the shape.
HW: Review my notes on the different ways triangles can look and how to show your work when finding area. (see first image above)
ALSO PLEASE DO NOT FORGET YOUR 2nd MSG for Monday. I will be signing agendas for unprepared for class if not.
Today we wrapped up the Unit 4 Test. I had a small few in each class who are not finished. If you have more than 4 problems, I would recommend coming in tomorrow morning before school at 8:20. Report to the cafeteria first.
If you have 4 or less problems you can finish within your class period tomorrow.
Students finished with tests will work on their CAPS 15 and Holiday Packet.
HW: If you did not work CAPS #15 last night for hw go to last night’s post to view the CAPS 15 problems and work them out.
