Skip Counting by 25s

Count by 25s

Counting by 25s means adding 25 each time. You can think of 25 as a quarter of 100, which helps you see why the numbers line up neatly. This pattern is also useful with money, because 25 cents is one quarter of a dollar.

Method

1. Start with the number given in the sequence.
2. Add 25 to get the next number.
3. Repeat the same step for every blank.
4. Keep the pattern steady; each answer should be 25 more than the one before it.

Helpful pattern idea

When you count by 25s, the last two digits often cycle through: 00, 25, 50, 75 Then the pattern repeats with the next hundred.

Check your work

To check, subtract 25 from a number you wrote. You should get the number just before it in the sequence. Also make sure the numbers increase evenly by 25, without skipping or changing the step size.

Example thinking

If a sequence starts 25, 50, 75, the next number is 100, because each term is 25 more than the one before it.
