Class Topics: 01.27.12

In EDM, students worked with volume and surface area.  We also introduced the area and circumference of a circle.  The focus was more on how to use the formula to calculate both the area and circumference when given to the student in a problem situation.
In class, students...

• completed several review problems that are reflective of the problems they will see on their Unit Five Summative Post-test.
• reviewed some skills using Khan Academy.  

For homework, students SHOULD...

• review/retake their Unit Five Pre-test.
• check over the  Unit Five Pre-test Answer Key located on the blog.
• use the Class Topics posts to help prepare for the assessment.
• practice the following skills on Khan Academy:
• Corresponding Angles 
• Geometric Terms
• Sum of Interior Angles of a Polygon
• Area and Perimeter Basics - Video
• Finding Congruent Triangles - Video
• Parallel Lines II

In Pre-Algebra, we introduced Lesson 6.4 - Area and Circumference of Circles using a hands-on approach to uncovering the relationship between circumference, diameter and Pi.  We then applied our new skills to some word problems that applied our understanding of area and circumference of circles to real-world scenarios.  

In class, students...

• used circular objects to uncover the mystery of Pi.
• worked with peers to solve  real-world problems that dealt with area and circumference of circles.

For Homework, students SHOULD...

• complete 6.4 - Problem Solving.  (handout)
• complete the following Khan Academy Skill:
• Video - Skill - use the word pi when answering some of the questions
