LCM

Find today’s problem below. The quiz tomorrow will be similar. For practice, what if one movie was 80 minutes and the other was only 30 minutes? If they started together at 4pm, when would they start together again?


Use prime factors to solve. You can use lists of multiples as well. To impress and get a level 4, you could also simplify the factors using exponents.

Prime Factorization

The grade 8s asked me to snap a photo of our examples today, so here…


When you’re done prime factoring, you’re left with only the prime numbers that are multiplied together to make the product you started with. You can simplify the expression by combining repeated primes using exponents.

Welcome Back!

Greetings parents and students of 7B and 8B!

I would like to welcome you to room 20. I hope you had as enjoyable a summer as I did, because its time to roll up our sleeves and get back to work.

My math and science programs will feature a balance of both student-led inquiry-based and more traditional teacher-led learning. Students will engage in hands-on activities, work in cooperative groups, and communicate their findings to peers in many different forms. I prefer more frequent, smaller assessments than exhaustive, lengthy ones. Please expect weekly or even bi-weekly quizzes as we chip away at the curriculum. Homework will consist of practicing for these quizzes.

Our classroom is fortunate enough to have an Apple TV and 16 iPads for student use, but anyone with access to a personal laptop or tablet is welcome to bring it with them to class as a learning tool. There will, of course, be strict rules of conduct associated with using all devices and each student will be responsible for their safekeeping. If you have any questions or concerns about this, please feel free to contact me.

We will be using Google Drive as our primary cloud storage and file creation tool at Franklin. Each student already has an account created for them by the HWDSB. I will teach them how to access that account from any computer or smart device and use the many tools available. The neatest feature, in my opinion, is the ability for students to share their work with other users. I plan to host a brief info session in my room during Meet the Teacher for any parent who is interested in learning how to view their child’s portfolio in Google Drive.

I look forward to meeting many of you on October 4th at Meet the Teacher and the rest during interview time in early December. If there is anything I can do to help before that, please let me know. The best way to reach me is by email.

Mr. Weingartner
