Wednesday/Friday Class: Divisibility Challenges 11/2/16
We worked through the worksheet Divisibility Challenges. We still have to finish the last three problems. The assignment for Friday is to use the digits 1, 3, 5, 7, 9 to compose a three digit number and a two digit number (without repeating any of the digits). For example, 975 and 31 could be used. With these two numbers, find the following:
1) The largest possible sum
2) The smallest possible sum
3) The largest possible difference
4) The smallest possible difference
5) The largest possible product (Show four possible answers for this one as it is trickier than you think.)
6) The smallest possible product

Tuesday/Thursday Class: More Powers 11/1/16
Students went to the board to show what they understood about the assignment. We went over some of the problems. See notes above.
Wednesday/Friday Class: Divisibility Rules 10/21/16
We went over the quiz and looked at the first question on Divisibility Challenges - What is the smallest positive integer that is divisible by 2, 3, 4, 5, 6, 8, 9, and 10? We looked at the prime factors and noticed that 8 contains 2 and 4, 10 contains 2 and 5, and 9 contains two 3s. Six is accounted for in the 8 and 9. When we multiply 8x9x5, the answer is 360.
Tuesday/Thursday Class: Powers of Ten 10/20/16
We went over the worksheets in class. Most students did not fully understand the worksheet More Powers. It will be due when we return on Nov. 1, 2016.

Wednesday/Friday Class: Divisibility Rules 10/19/16
We had a "pop" quiz on divisibility rules. See the attachment above. We took notes on more divisibility rules. See link above. The homework is called Divisibility Challenges. Students should work to understand what is being asked and should come to class on Friday with questions. The worksheet is due the week after conferences.
Tuesday/Thursday Class: Powers of Ten 10/18/16
We can use powers of ten to describe numbers in a type of shorthand form. Most powers of ten have special names. Once commas enter the picture, we can talk about powers of 1,000. We are beginning to learn some exponent rules. Students should be able to write numbers as the product of a number and a power of ten. This is the precursor to learning scientific notation. We had two worksheets. One is for practice. The one labeled More Powers is due on Thursday, 10/20/16.
