Reading, Writing and Comparing Numbers in Millions

Lesson Outline

Did you know that the diameter of the Sun is about 1,392,082 km?

Vocabulary of the day!

Diameter is the distance that passes through the centre.

Reading Numbers in Millions

We can use a place value chart to write the number where each digit

represents a value. Example: 1,392,082

Reading Numbers in Millions

We also have values in the hundred thousands, tens of thousands, thousands, hundreds, tens and ones. Let’s read each digit’s place value.

Reading Numbers in Millions

This time, we’ll read them as a group of millions, thousands and hundreds!

This means that we read the number

1,392,082 as one million three hundred ninety-two thousand eighty-two.

Can we see an object that is 149,600,000 kilometres away?

Can you guess what the object is?

Hint: We see it everyday!

The Sun is around

one hundred forty nine million six hundred thousand

kilometres away!

Mercury to the Sun is

57,900,000 km

Venus to the Sun is

108,200,000 km

Comparing Numbers

Between Mercury and Venus, which planet do you think is closer to the Sun?

Comparing Numbers

Let’s use the place value chart to compare the two numbers.

From the number 108,200,000 we have one hundred million, which is bigger than fifty million from 57,900,000.

One hundred Million

Fifty Million

Mercury to the Sun is 57,900,000 km

Venus to the Sun is 108,200,000 km

Comparing Numbers

<

The distance of Mercury to the Sun is less than the distance of Venus to the Sun.

Recall: In comparing numbers, we use the symbols greater than (>) and less than(<)

Example: 500 > 250 , 15 < 20

Compare the distances of Mars, Venus and Mercury from the Sun using the greater than or less than symbol!

Sun to Mercury is

58,000,000 km

Sun to Mars is

230,000,000 km

Sun to Venus is

108,000,000 km

Summary

In reading numbers, we start from the digit with the highest place value.

5,682,357

Summary

In comparing numbers, we can use the place value chart.

Since 5 < 7, we can say that

We compare the greatest values.

5,672,357 7,547,012

A spacecraft from Earth wants to visit our Moon! What is the distance between the Moon and Earth, considering that the Moon is 150,000,000 km from the Sun, Earth is 149,600,000 km from the Sun, and Earth is in between the Sun and the Moon?
