Addition patterns over increasing place values

Learn with an example

➡️ Complete the pattern:

3 + ____ = 8

30 + ____ = 80

300 + ____ = 800

Find the first missing number:

3 ones + 5 ones = 8 ones
3 + 5 = 8

Now complete the pattern:

3 tens + 5 tens = 8 tens
30 + 50 = 80

3 hundreds + 5 hundreds = 8 hundreds
300 + 500 = 800

➡️ Complete the pattern:

 _____+ 1 = 4 

______+ 10 = 40

_______ + 100 = 400

Find the first missing number:

3 ones + 1 one = 4 ones
3 + 1 = 4

Now complete the pattern:

3 tens + 1 ten = 4 tens
30 + 10 = 40

3 hundreds + 1 hundred = 4 hundreds
300 + 100 = 400

➡️ Complete the pattern:

8 + 8 = _____

80 + 80 = _____

800 + 800 = ______

First, add:

8 ones + 8 ones = 16 ones
8 + 8 = 16

Now complete the pattern:

8 tens + 8 tens = 16 tens
80 + 80 = 160

8 hundreds + 8 hundreds = 16 hundreds
800 + 800 = 1,600
