## Spectrum Math Grade 2 Chapter 6 Lesson 6.16 Comparing Measurement Answers Key

Use a ruler to measure each object in centimeters. Then, measure again using the line of squares.

Answer:

Step 1:Place the object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

The given object is 14 cm long.

Using the line of squares, it is occupying 28 squares.

Answer:

Step 1:Place the object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

The given object is 7 cm long.

Using the line of squares, it is occupying 14 squares.

Answer:

Step 1:Place the object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

The given object is 15 cm long.

Using the line of squares, it is occupying 30 squares.

What do you notice about the measurements in centimeters compared to those in squares?

What explains this?

Answer:

For the above objects, the length of the objects using line of squares is twice the length using the ruler.

For example, the length of the pen is 14 cm long when measured using ruler and the same is occupying 28 squares.

Here, 28 is twice of 14, 14×2=28

Thus, we can say that the length of objects using squares is two times the ruler length.

Use a ruler to measure each object in centimeters. Then, measure again to the nearest inch.

Answer:

Step 1: Place the first object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

Step 3: The given object is 2cm long when measured using cm ruler and is about 1 inch long.

Now, place the second object beside the ruler and measure the length.

The length of second object is 4cm when measured using cm ruler and is about 2 inches long.

Answer:

Step 1: Place the first object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

Step 3: The given object is 10cm long when measured using cm ruler and is about 5 inches long.

Answer:

Step 1: Place the first object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

Step 3: The given object is 8cm long when measured using cm ruler and is about 4 inches long.

Answer:

Step 1: Place the first object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

Step 3: The given object is 14cm long when measured using cm ruler and is about 7 inches long.

Answer:

Step 1: Place the first object beside the ruler, starting from point 0 on it.

Step 2: Look at the endpoint and mark the value.

Step 3: The given object is 12cm long when measured using cm ruler and is about 6 inch long.

What do you notice about the measurements ¡n centimeters compared to those in inches? ____________________________

Answer:

From the above numbers, we can observe that the measurements in centimeter is greater when compared to those in inches.

Also we can observe that the centimeter is two times the inches, that is 1 inch is approximately equal to 2cm.

What explains this? _____________________________________

Answer:

When converting from a larger unit to smaller units, we will have the more of smaller units.

As the given lengths have more cm than inches, we can say that the centimeters are smaller than inches.

When converting from a larger unit to smaller units, we need to multiply and when converting from smaller units to larger units we need to divide.
