Math with Mr. Wakild or Mrs. Henderson
Sorry for the delay in getting our posts up - it's been a crazy start to the year! We'll be much better about it going forward. We will use this web site as a place to post resources for parents and students - practice work, videos, etc. Also we'll share upcoming events, like projects, tests, or quizzes.
On that note, there will be a summative quiz next Thursday, Sept. 8th. It will cover four topics:
1. Adding, subtracting, multiplying, and dividing positive and negative numbers
2. Adding and subtracting fractions (think: common denominator!!)
3. Multiplying fractions (cross simplify!)
4. Dividing fractions (multiply by the reciprocal!)
5. Order of Operations (PEMDAS)
Check out the past week's Must Do's - if students can ace these, they are ready for the quiz. Have them practice them again!!
Here are some Khan Academy videos to help students review. With all Khan videos, check out the practice problems on the left side of the screen.
Adding and Subtracting Fractions
Multiplying Fractions (with cross simplifying!)
Order of Operations
Here are some practice problems that would be good to review:

Science with Mrs. Gnojewski
-Create and discuss of a model of how waves (electromagnetic) are reflected, refracted, absorbed, emitted and transmitted by different materials.
-Explain the geocentric and heliocentric models of the Solar System.
This week seventh grade students wrapped up their investigation into the behavior of light by completing a summative assessment on Thursday. Light will continue to play a role in our discussions as we move into exploring the motions and cycles of objects in the Solar System. Students began to take a historical approach to understanding the role of technology in changing the way we view the Solar System by exploring the geocentric model proposed by Ptolemy. We will continue our exploration with a lab next week. In addition, students continue to collect data about the phase of the moon daily.
What is the geocentric model?
