Multiplying Whole Numbers by Fractions with Models

This video tutorial teaches how to multiply whole numbers by fractions, starting with an introduction to the concept and its real-life applications, such as cooking and sharing. The process is explained by focusing on multiplying the numerator while keeping the denominator the same, akin to repeated addition. The video includes examples and practice problems to reinforce understanding, using models to visualize the multiplication process.

What is a real-life scenario where multiplying a whole number by a fraction is useful?

• Calculating the area of a circle

• Doubling a recipe

• Measuring the speed of a car

• Determining the height of a building

When multiplying a fraction by a whole number, what remains unchanged?

• The fraction's value

• The whole number

• The denominator

• The numerator

What does the numerator in a fraction represent?

• The size of each piece

• The total number of pieces

• The color of the fraction

• The shape of the fraction

How can multiplying fractions by a whole number be visualized?

• Creating a bar graph

• Drawing models

• Using a pie chart

• Using a line plot

Why do we keep the denominator the same when multiplying a fraction by a whole number?

• Because it makes the calculation easier

• Because it represents the size of each piece

• Because it changes the value of the fraction

• Because it represents the total number of pieces
