Our math lessons this week will be about finding the greatest common factor (GCF) of a set of numbers. Be careful not to get GCF mixed up with LCM that we studied last week; this is the most common mistake students make when working with the two. First, I will show you how to use our handy-dandy Montessori peg board to find the GCF of numbers. Then, we will move onto some other strategies you can use. You will have homework Monday and Tuesday evening. Your math journal will be due Thursday. You will have a quiz on GCF Thursday. As you work through the week, check out this sheet if you'd like some extra practice finding GCF. The answers are found at the bottom of the page.
You can also visit this fun game called "Sketch's World" where you must help a pencil-drawn person escape some evil erasers...while answering some GCF problems along the way! Click the picture below to play!

We will continue investigating minerals this week. We will spend some time discussing mining of minerals just like the ones you've been using in class. I know you will enjoy the lab I have planned for you this week!
Remember that you must complete three choices on your Tic Tac Toe sheet by Friday. You will also have a test on minerals Friday. You can use your notes and study guide to help you prepare.
This Friday is picture day! You are free to dress down for the day, but be sure to wear your smile! Finally, don't forget that Labor Day is on Monday, September 1. There will be no school that day.
Enjoy your weekend,
