Unit 5 Data: What does it all MEAN?

This week we will begin our data and statistics unit in seventh grade math.  The essential questions that we will answer through our studies include the following:

How can predictions and decisions be made about a large population?
What is a measure of variation?
How is the shape of the data use to analyze data?

We will begin with the third question this week as we look closely at the results of the Unit 5 Post-test.

The follow illustration shows our achievement compared to all seventh-graders in the district.

Standard / Cluster	Hoyt Middle School 53 Students	District Average
MA.7.7.G.6 (7) Curriculum Resources (41)	62.64%	44.74%
MA.7.7.G.1 Curriculum Resources (16)	53.21%	50.97%
Questions	64.2%	53.8%
Overall Exam	64.2%	53.8%
MA.7.7.G.4 (7) Curriculum Resources (12)	64.72%	59.18%

Finding Pi

Did somebody say banana cream?

Unfortunately the pi we were looking for is the constant that describes the relationship between the circumference of a circle and its diameter (about 3.14).  Pi-seekers measured the circumference and diameter of several round objects and then expressed the relationship as the ratio, C/d. To our surprise, we calculated the ratio as a number close to pi--every time! This week we will continue our study of circles by calculating their areas.  We will also explore the volume of rectangular prisms (boxes) and the surface area of polyhedra.

Calendar for the week of March 4 through March 8

Monday: Finding Some More Pi

Tuesday: Calculating the Area of Circles

Wednesday: Polyhedra

Thursday: Exploring the Volume of Rectangular Prisms, CFA 5.4

Friday: More Practice with Volume, Retake CFA 5.4

Coming next week:

Monday: In class review for Unit 5 Post-test: Geometry

Tuesday: Correction of review and game

Wednesday: Unit 5 Post-test: Geometry

Thursday: Oz: the Great and Powerful, review games in blocks 1 and 5
