Patterns with Place Value

Patterns with Place Value

• What is true about this pattern?

• 6, 60, 600, 6000

• Think: Do we notice anything about these numbers?

• The 6 goes from the ones place, to the tens place, to the hundreds place, to the thousands place.

• Each time we go up a place value, that place is ten times bigger than the place value to the right.

Patterns with Place Value

• What is true about this pattern?

• 6, 60, 600, 6000

• Think about using multiplication here:

• 6 x 1 = 6

• 6 x 10 = 60

• 6 x 100 = 600

• 6 x 1,000 = 6,000

The number we’re multiplying by gets

ten times bigger each time and so does our product!

Patterns with Place Value

• What is the next equation?

• 4 x 7 = 28

• 40 x 7 = 280

• 400 x 7 = 2,800

• 4,000 x 7 = 28,000

Patterns with Place Value

• What is the next equation?

• 4 x 7 = 28

• 40 x 7 = 280

• 400 x 7 = 2,800

• 4,000 x 7 = 28,000

Do you notice a pattern?Each number is getting

ten times bigger!

Patterns with Place Value

• What is the next equation?

• 4 x 7 = 28

• 40 x 7 = 280
