### Target 1​

###### Lesson Type:

New

Measurment

:

Techniques and Formulas

Calculate circle measurements.

###### 1:

Identify Pi (π) as a constant of all circles.

###### 2:

Determine that Pi (π) is a ratio of circumference to diameter.

###### 3:

Recognize that Pi (π) is generally represented by 3.14.

7th

###### Vocabulary:

CIRCUMFERENCE, DIAMETER, PI

Activities:

- Measured the circumference and diameter of six different sized circular objects and calculated the ratio of circumference to diameter; organized results in a table.

- Determined the average of all the ratios and recognized that all ratios were a little greater than 3, approximately 3.14. Defined this ratio as "pi".

## Absent Students:

### Target 2

:

###### 1:

Use the graphic representation of a variable relationship to determine the proportions present.

###### 2:

Understand that the type of relationship present between two variables can easily be seen when graphed.

###### 3:

Use graphs, equations, and ordered pairs to examine the relationship between variables.

7th

###### Vocabulary:

PROPORTIONAL LINEAR RELATIONSHIP, CONSTANT OF PROPORTIONALITY

Activities:

- Graphed the relationship between circumference and diameter on a coordinate plane.

- Defined the relationship as "proportional" and recognized pi as the "constant of proportionality".
