Number Operation

:

Fractional Numbers

Convert between fractions, decimals, and percentages.

Supporting targets:
1:

Describe the relationship between fractions, decimals, and percentages.

2:

Identify the fractional equivalent of a percent.

3:

5:

Grade:

6th

Vocabulary:

Percent, Fraction, Numerator, Denominator

Activities:

  • Reviewed and discussed the relationship of fractions to division.
  • Listed words with "cent," e.g., century, centimeter, and how they related to 100.
  • Learned that "percent" can be thought of "for every hundred," or "out of 100," which makes converting 43% "43 out of 100," and can be written as the fraction 43/100.
  • Converted fractions into percentages.
  • For fractions with a denominator other than 100, use multiplication and/or division to find an equivalent fraction with a denominator of 100 to find its percent.

Challenge Problem:

Convert the given fractions into percentages using multiplication and/or division where applicable.

Challenge Data:

1) 87/100
2) 14/25
3) 75/500
4) 60/150
5) 28/40

Guiding Questions:

When working with percent, what is the magic number you want to work with? 100

  • This denominator is tricky because it is not 100. How can we turn this denominator into 100? Use multiplication or division. Sometimes we need to do both.
Challenge Answer:

1) 87%
2) 56%
3) 15%
4) 40%
5) 70%

Measurment
Techniques and Formulas
Understand that circles have specific measurements.

:

Supporting targets:
1:

Understand circumference is the distance around the edge of a circle.

2:

Understand radius is the distance from the center point to the edge of a circle.

3:

Understand diameter is the distance from one side of the edge of a circle to the other.

4:

Measure the diameter of given circles.

5:

Understand the relationship between the radius and the diameter of a circle (use the radius to find the diameter or the diameter to find the radius).

Grade:

4th

Vocabulary:

Radius, Diameter, Circumference, Cord, Center Point

Activities:

  • Discussed properties of circles, e.g., 2-D, no sides.
  • Learned new vocabulary terms that are differnet measures of a circle, i.e., radius, diameter, circumference, and cord.
  • Discovered the relationship between a circle's diameter and radius.
  • Used a geoboard and bands to illustrate and represent the vocabulary terms.
  • Measured various circular objects to find its radius, diameter, and circumference.
  • Determined that a circle's diameter is its longest cord.

Home Exploration

Search your home for different round objects. Make a table and lust the items to compare and keep track of the radius, diameter, and circumference.

  • Review vocabulary terms: radius, diameter, circumference, cord.
  • What is the relationship between radius and diameter? How can you use one measure to find the other?
