Seventh Grade Math: Englewood School Mrs. Armstrong

Hello Everyone! I hope you are doing well. Please let me know if you need anything. I hope last week’s assignment went well. This week, April 27- May 1, I have assigned optional review from

Module 5 and Module 6. This week’s will be same format as last week. I am attaching an answer key this week so that you can assess how you are doing.

How to get started: You can print these 4 pages at home and then write on those. If you cannot print at home, you have some options.

o You can label a piece of notebook paper by the name of the assignment at the top of the page. For example, the first sheet would be “Module 5: Quiz B”. Then you could write responses on the notebook paper.

o Lastly, you can get a hard copy at the school at the bus ramp on Mondays and Thursdays before 12:30. Just drive up, and let them know what you need!

If you’re having trouble on the assignment:

Log on to your Go Math account. o Go to my.hrw.com o Your username is typically your long lunch number or first.last name. o Password is usually test123. o If you do not have the correct login information, check your login sheet in your math journal. o If you are still having trouble, please email me. earmstrong@mcminnschools.com

Once you are logged in: o Make sure the drop-down box says seventh grade.

Option one: Click Student Resources. Scroll down until you see “Videos” Click on “Math on Spot Videos” Watch any video for Module 5 and 6. If you’re having trouble on a Module 5

review, make sure the video’s name begins with the number 5. Option two:

(From the home screen) Click on Interactive Student Edition Then, click on the appropriate Module for support and extra practice.

You may also email me at earmstrong@mcminnschools.com. While emailing, o I can answer specific questions. o We can set up a time for me to call you and discuss the material further.

Currently, my “office hours” are 8:30-12:30. I will reply to emails quickly during that time and can call you if an appointment time is needed. If you need an appointment time outside of that time range, we can do that, too.

Please know, this work is optional and will not be held against you. I want to be here to help you in any way I can. Unfortunately, this current worldwide situation has caused “school” to look a bit different! However, I am still your teacher nevertheless! I am happy to help you. Please let me know how I can. Talk to you soon!

Sincerely,

Mrs. Emilee Armstrong
