Application Problem

(from lesson 7)

Justin put a 1-kilogram bag of flour on one side of a pan balance.

How many 100-gram bags of flour does he need to put on the other pan to balance the scale?

Concept Development

Part 1: Use a pan balance to make a bag of rice that weighs 1 kilogram.

Part 2: Decompose 1 kilogram.

**Homework**

1. Use the chart to help you answer the following questions:

a. Isaiah puts a 10 gram weight on a pan balance. How many 1 gram weights does he need to balance the scale?

b. Next, Isaiah puts a 100 gram weight on a pan balance. How many 10 gram weights does he need to balance the scale?

c. Isaiah then puts a kilogram weight on a pan balance. How many 100 gram weights does he need to balance the scale?

d. What pattern do you notice in Parts (a - c)?

2. Read each digital scale. Write each weight using the word kilogram or gram for each measurement.

2. Read each digital scale. Write each weight using the word kilogram or gram for each measurement.

A kilogram is a unit used to measure weight.

To record 1 kilogram, we abbreviate the word kilogram by writing kg.

1 kg = kilogram.

The whole bag contains 1 kilogram of rice. We just partitioned the rice into 10 equal parts. These equal parts can be measured with a smaller unit of weight called grams. Each part is 100 grams.

How many hundreds are in 1 kilogram of rice? 10 hundreds

How many grams of rice are in the whole bag? 1,000 grams!
