Understanding Fractions on a Ruler

This video tutorial teaches how to create and use a ruler to measure objects to the nearest one-fourth, one-half, three-fourth, and one whole. It explains the concept of dividing whole numbers into halves and fourths using a number line, and how these fractions can be represented differently. The tutorial also guides viewers through the process of creating a ruler by marking whole numbers, halves, and fourths, and demonstrates how to use the ruler for precise measurements.

What is the main goal of this lesson?

• To learn how to create a ruler

• To practice addition and subtraction

• One whole

• One-fourth

Why might it be acceptable to round to the nearest whole number?

• When using a digital ruler

• When measuring very small objects

• When precision is not important

• When measuring in centimeters

What is the first step in creating a ruler with fractional measurements?

• Marking the whole numbers

• Marking the halves

• Drawing the outline
