A big thanks to Mother Nature and our chaperones for helping our students to have such a wonderful day at Kettle Cove. We found many creatures and look forward to the slide shows that students will make later this week with the pictures that were taken today. Enjoy some of the pictures that I took of the group enjoying the tide pools :) We worked today with transitioning from factor strings into exponential notation. We practiced with several factor trees/charts and talked about how to make sure that the exponent was smaller and to the top of the number so that it didn't just look like a sloppy two-digit number :)
In-class assignment: complete and turn in page 95 from book Today we finished up our swingers with testing the variable of length. We found that the length of the swinger made a noticeable difference in the number of swings that our pendulums could complete. We graphed these on picture graphs today and will continue tomorrow by completing coordinate graphs.
Chris Carey from Eimskip came to talk to the grade about our upcoming trip to Eimskip. He talked about the changing infrastructure and how Eimskip reaches places within our country and across the world.
We also had a great opportunity to FaceTime with two people at the top of the big crane who talked about the port and their jobs there. All students are looking forward to going to the Port in a couple of weeks! Today the Arbours worked on continuing their pendulum trials. We finished up our trials where the manipulated variable was the angle of the string to start. Most data supported that the angle of the string did not change the number of swings that the pendulum could complete. We were also able to run a trial testing the weight of the bob (end part) to see if it impacted the number of swings. We did not have a chance to go over our data.
Today we reviewed using factor trees to find prime factorization and then followed up with a different strategy. We practiced whole-group and independently.
Homework tonight: IXL F.2 to 85% Today we worked on prime factorization. We practiced creating factor trees to determine which prime factors are used to make the prime factorization for each number. Unlike the textbook, I encourage students to circle any prime numbers, because I have found that it is easier for students to track the primes that they will include in their factor strings.
Homework tonight: page 85 and 86 (beware, number 5 is challenging) Today students were given a permission slip for a second field trip that we are taking in October. The Newtons will be going to Eimskip on Tuesday, 10/17 and the Arbours will be going on Thursday, 10/19. The trip is in the afternoon and each homeroom will be looking for a few chaperones to join us. We are going to be learning about how local people use science concepts in the real world.
We also started talking about our first investigation on pendulums. Students generated a list of variables that could affect the number of circuits that a pendulum could complete. We will be testing the angle of the string tomorrow, so students came up with their hypothesis as to how this would change the number of circuits. We start our trials tomorrow....more to come :) No Homework Today we watched a video on Prime and Composite numbers. We then completed an activity (like the one in the video) together to color a hundreds chart showing Prime, Composite and Unique numbers. One class was able to try out their skills on IXL.
Homework tonight: IXL F.1 to 85% (considered proficient by IXL) |
