​Math Antics Base Ten Notes

Drag and Drop

The number system that we us is called [ ​

Placeholder

] because it uses [ ​

Placeholder

] different symbols for [ ​

Placeholder

] The ten symbols that we use are called [ ​

Placeholder

] The ten digits that we us are ​

Drag and Drop

Think of a [​

] as a [ ​

Placeholder

] that is only big enough to hold [​

Placeholder

] at a time. The first number place can represent [​

Placeholder

] to [​

Drag and Drop

To count any higher we need to [​

Placeholder

] a new [​

Placeholder

], because it is being used to count [ ​

Placeholder

] of ten, it’s allowing us to [​

Placeholder

] our original ten [ ​

Placeholder

], but this time they are able to count bigger amounts. ​

Drag and Drop

In fact, using only our [ ​

Placeholder

] digits and these [ ​

Placeholder

] number places, we can count all the way from [​

Placeholder

]. At ninety-nine, both our number places are maxed out with the highest digits and we won’t be able to [​

Placeholder

] higher unless we get another [ ​

Placeholder

]. ​

Drag and Drop

We can use the new number place to count how many [ ​

Placeholder

] of [ ​

Placeholder

] we have. Have you noticed that each time we get a new [​

Placeholder

] to count larger groups we placed it to the [ ​

Placeholder

] of the previous number place, that is important because number places are always arranged in the exact same [  ​

Drag and Drop

Did you also notice that each number place to the left represents groups that are exactly [​

] times [  ​

]than the previous [​

]. The next number place is the [​

In the U.S. we use a [  ​

Placeholder

] to separate every three places. ​

Place Value

Times Ten

When we multiply by ten, we are moving one place left on the place value chart. Any place missing a digit, needs a zero.

• 1 x 3 = 3

• 10 x 3 = 30 (3,6,9,12,15,18,21,24,27,30) can also say 3 x 10 = 30

• 100 x 3 = 300 (can also say 30 x 10)

• 1000 x 3 = 3000 (can also say 300 x 10)

Do you notice the pattern?

• 1 x 5 = 5

• 10 x 5 = 50

• 100 x 5 = 500

• 1000 x 5 = 5000

Multiple Choice

What is the missing number?

100 x 6 =

• 6

• 60

• 600

• 6000

Multiple Choice

10 x __ = 40

• 4

• 40

• 400

• 4000

Multiple Choice

What is the missing number?

__ x 7 = 7000

• 1

• 10

• 100

• 1000

Multiple Choice

Finish the pattern:

1 x 8 = 8

10 x 8 = 80

100 x 8 = ?

• 80

• 800

• 8000

• 80,000

In the number 34, 239

• The value of the 3 in the ten thousands place is 1,000 times greater than the value of the 3 in the tens place

• (I skipped 3 places)
