Learning Targets:
I can prove:
Circumference of a circle is "approximately" 3x length of the diameter for all circles.
Circumference/Diameter = "pi" (approx= 3.14) which is a "ratio"
In class:
- Revisited the "pi Scavenger hunt"
- Mrs. White used "yarn" to demonstrate that approximately 3 diameters = circumference of a circle (pi = 3.14)
- Used the relationship to predict circumference or diameter of a circle
- Students began sharing their "Proportion Presentations"
Homework:
page 319 problems 13, 15, 17page 283 problems 16 & 18
QUIZ TOMORROW:
- Prove if 2 ratios form a proportion
- Solve proportion problems for an unknown
- (word problems similar to presentations in class)
