Why look at counting, it’s easy?

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20…

We can do the same with our 10s or 100s as well:

Counting up in 10s and hundreds get’s trickier when we don’t start with a number in the 10s or 100s.

What is 237+10?

We’re just adding an extra ten to the 3 we already have, so we must have 4 now.

30+10=40

237+10=247

Just like with 10s and 100s, we can do the same with 1000s.

What is 6387+1000?

We’re just adding an extra ten to the 3 we already have, so we must have 4 now.

6000+1000=7000

6387+1000=7387

For practice finding 1000 More or Less, click here.

Counting starts to get tricky when we aren’t using numbers that start with a 1 and end with lots of 0s. Luckily though, counting is really just your times tables.

Example

Find the next number in the sequence 36, 40, 44, 48,…

We are counting up in 4s, so the next number is going to be 48+4=52

For practice more practice counting in multiples of 4, 8, 25, and 100, click here.

Things get EVEN TRICKIER when we are looking at numbers like 7!

Example

Find the next number in the sequence: 42, 49, 56, 63,…

We are counting up in 7s, so the next number is going to be 63+7=70

## Example Questions

What is 2568-100?

500-100=400

2568-100=2468

Find the next number in the sequence: 24, 30, 36, 42,…

We are counting up in 6s, so the next number is going to be 42+6=48
