Maria introduces a lesson on measuring to the nearest centimeter using a ruler. She demonstrates how to measure lines, estimate and measure pencil lengths, and measure the height of chess pieces. The lesson emphasizes the importance of aligning the ruler correctly and understanding that measurements may not always be exact.

What is the primary tool used in this lesson to measure objects?

• A compass

• A protractor

• A measuring tape

• A ruler

Why is it important to align the zero line of the ruler correctly when measuring?

• To avoid measuring the wrong object

• To ensure the ruler is straight

• To get an accurate measurement

If a line is slightly shorter than 6 cm, how should it be recorded?

• As exactly 6 cm

• As about 6 cm

• As less than 5 cm

• As more than 7 cm

What is the purpose of estimating the length of an object before measuring it?

• To practice guessing

• To save time

• To avoid using a ruler

• To compare with actual measurements
