Estimating Measurements with Rulers

This video tutorial teaches how to measure using a ruler. It explains the use of large and small increments on a ruler and provides examples of measuring objects by estimating between markings. The tutorial emphasizes focusing on one digit at a time and estimating where necessary to achieve accurate measurements.

What is the total number of large increments on the ruler?

• 15

• 20

• 10

• 5

How many smaller increments are there between each large increment?

• 12

• 8

• 10

• 5

If a block ends halfway between 0.4 and 0.5, what is its estimated measurement?

• 0.50 cm

• 0.45 cm

• 0.55 cm

• 0.40 cm

In the first example, what is the final measurement of the block?

• 0.40 cm

• 0.35 cm

• 0.45 cm

• 0.50 cm

What is the measurement of the block in the second example?

• 1.20 cm

• 1.25 cm

• 1.30 cm

• 1.15 cm

In the second example, between which two increments does the block end?

• 1.1 and 1.2

• 1.3 and 1.4

• 1.4 and 1.5

• 1.2 and 1.3

What is the key step in estimating the measurement of a block?

• Using only large increments

• Focusing on one digit at a time

• Guessing the measurement

• Ignoring smaller increments
