Count in 6, 7, 25, and 100 | Year 4 Maths Resources

What you need to know

Things to remember:

  • We can learn patterns for count in 6s, 25s, and 100
  • The best way to learn how to count in 7s is to practice.

Usually, when counting up in multiples, we just need to find the next number, which is the same as counting up in our times tables! So, how would we find the next number in this list 6, 12, 18, 24…?

Step 1: Notice how much we add each time.

6 \textbf{+6} = 12

12 \textbf{+6} = 18

So, the numbers are going up by 6 each time.

Step 2: Add your number from Step 1 to the last number you have.

24 \textbf{+6} = 30

Extra: We can keep counting in multiples of 6 by adding the same amount each time!

30, 36, 42, 48, 54…

Although 25 and 100 are big numbers, they’re actually quite easy once we learn the pattern!If we look at the first 9 lots of 25, we can see a nice pattern:

0, 25, 50, 75, 100, 125, 150, 175, 200, 225 …

We can see that there is a repeating pattern of 0, 25, 50, 75, with just the 100s ever really changing.

700, 725, 750, 775, 800, 825, 850, 875, 900…

Remember how easy counting in 10s is? Well counting in 100s is just as nice, all we have to do is put a 0 on the end!

10, 20, 30, 40, 50…

100, 200, 300, 400, 500…

 7s are the hardest to count up in, because we don’t have a nice pattern until we reach 70.

7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91 …

 Tip: Practicing adding 7s to a single digit number is helpful for seeing what the units of your next number will be!
