Men's Olympics Basketball Ratios

Introduction (5 minutes)

Begin by asking students, "What is a comparison?"
Elicit responses such as comparing height, size, or number.
Explain that today, we're going to learn about a special kind of comparison called a ratio.

Exploration (15 minutes)

Gather a collection of objects (e.g., 5 pencils and 3 crayons).
Ask students how many pencils there are. (5)
Ask students how many crayons there are. (3)
Introduce the term "ratio" and explain that it compares two quantities.
Write the ratio of pencils to crayons on the board as 5:3.
Explain that this means for every 5 pencils, there are 3 crayons.
Repeat with different objects and combinations.
Introduce the idea of part-to-part ratios (e.g., pencils to crayons) and part-to-whole ratios (e.g., pencils to total objects).

Explanation (10 minutes)

Recap the concept of a ratio as a comparison of two quantities.
Emphasize the importance of order in ratios (e.g., pencils to crayons is different from crayons to pencils).
Explain that ratios can be written in different ways:
With a colon (e.g., 5:3)
As a fraction (e.g., 5/3)
In words (e.g., 5 to 3)
Provide examples of each form.
