## October 3rd

We defined integers as whole numbers and their opposites.

### Homework:

On a separate piece of paper, draw a picture that illustrates a real - life use of negative integers (it can just be simple sketch but I would be happy to hang some up in the room). Write a sentence or two that explains how negative numbers are used in your picture.

## October 2nd

We learned about how zero was first used in equations and researched the properties of whole numbers. We completed a chart in Google Classroom

### Homework:

• Properties worksheet

## October 1st

We learned about the binary place value system and how it is used.

• sections 1.4 - 1.6 in workbook
• Review Jeopardy

## September 24th

We learned different strategies for finding the LCM (list of multiples, factor trees and box method)

### Homework:

Complete page 26 in workbook

## September 21st

Finish Google Classroom work on factor trees, GCF and LCM

## September 20th

We applied out knowledge of factor trees and greatest common factor.

### Homework:

Finish classwork if you didn't (setting the table) and try bonus

BONUS: A certain natural number has exactly 8 factors. Two of the factors are 15 and 21. What is the sum of all 8 factors?

## September 18th

Today we went over the number theory homework and students shared how to use excel spread sheets to help solve the problems. We also learned the fundamental theorem of arithmetic (see unit of study) and learned how to make prime factorization trees.

### Homework:

Watch this flip lesson video and take notes (direct link is on Google Classroom)
