Why find Prime Factors?A prime number can only be divided by 1 or itself, so it cannot be factored any further! Every other whole number can be broken down into prime number factors. It is like the Prime Numbers are the basic building blocks of all numbers. This idea can be very useful when working with big numbers, such as in Cryptography. Cryptography is the study of secret codes. Prime Factorization is very important to people who try to make (or break) secret codes based on numbers. That is because factoring very large numbers is very hard, and can take computers a long time to do. If you want to know more, the subject is "encryption" or "cryptography".

In our daily Number Talks, we are learning about Powers of 10 and how they work to multiply both whole and decimal numbers.
Powers of 10 are short form ways to write 10, 100, 1000, 10000, 10,000,100,000,etc. When multiplying a power of 10 by a whole number you just add the same number of zeros as in the power. I've add some links to YouTube videos that may help you understand how these multiplication problems work. https://www.youtube.com/watch?v=YJdCw2fK-Og https://www.youtube.com/watch?v=UxLQSRk8KbY You've got your Math Reference Book at home with you this weekend. Try to solve the multiplication problems in your book. You can hold off on the decimal problems-as we will tackle those next week. For our first unit in grade 7, we will be reviewing whole numbers from 1- 1, 000, 000.
Students have already completed a Diagnostic Test for this unit,which will allow me to see where there are gaps in their understanding of whole numbers to 1, 000,000. We will be using a resource called Gap Closing, Unit 3 - Representing and Renaming Whole Numbers. This resource was written by the Ministry of Education. If you'd like to look at the resource, I've attached a link to the student book. http://www.edugains.ca/resourcesMath/CE/LessonsSupports/GapClosing/NumberSense_Junior-Int/GCU3_SB_RepresentingandRenamingWholeNumbers.pdf |
