## Math in Focus Grade 2 Chapter 8 Practice 1 Answer Key Measuring in Kilograms

Fill in the blanks.

Question 1.

Explanation:
1. Choose a scale that measures in grams. Make sure the scale can handle the size of objects you plan on weighing. Since a gram is a metric unit of measurement, your scale needs to use the metric system. Scales are available in digital and mechanical models.
2. Weigh an empty container first before putting an item in it. If you plan to measure something you can’t put directly on the scale, weigh the container before putting the item in it.
3. Press the tare button to zero out the scale. The mysterious button labelled “tare” on digital scales is a reset button. Press the tare button after each item you measure on the scale. If you weighed a container, you can fill it now.
4. Set the object you wish to measure on the scale. Place your object in the centre of the scale. If you measured a container first, you can now put the object you wish to measure inside the container. The scale will then calculate the heaviness of your object.
5. Finish weighing the object on the scale. Wait for the scale’s digital display or needle to come to a stop. When it finishes moving, read the number to find out how heavy the object is. Make sure that the weight is in grams. Then, remove your object and hit the tare button again to reset the scale.

Question 2.

The mass of the package is ____ 1 kilogram.
Explanation:
1. We will compare the weights of pear and 1 kg stone by placing them on each end of the scale.
2. The 1 kg stone pushes the scale down more than the pear pushes down.
3. The side with 1 kg moves downwards, causing the side with the pear to move upwards.
4. The 1 kg stone is heavier than the pear.
5.  The pear is lighter than 1 kg stone.
6. It doesn’t matter what size the object is, the heaviest object moves downwards on the scale.

Question 3.

The mass of the package is ___ 1 kilogram.
Explanation:
The measuring scale is showing 1.5 kg which means higher than 1 kg.

Question 4.
The ___ is the lightest.
The pear is the lightest.
Explanation:

1. The 1 kg stone moves downwards so it is heaviest.
2. The pear is in upwards so it is lightest.
3. From this we can say pear is less than 1 kg.
4. Therefore, it is the lightest.

Question 5.
The ___ is the heaviest.
Explanation:

1. On the digital display the scale is showing 1.5 kg means which is more than 1 kg.
2. So the mass of the package is 1.5 kilograms.
3. Therefore, the package is the heaviest.

Read each scale. Then write the mass.
