What is Skip-Counting?

Skip-counting is when we count by numbers other than one. For example, instead of saying 1, 2, 3, 4, 5, we can skip-count by twos (2, 4, 6, 8) or by fives! When we skip-count by fives, we say every fifth number in order.

Why is Skip-Counting by Fives Important?

Skip-counting by fives helps us count things quickly. It is useful when you have lots of items, like counting coins or blocks. It also helps us with addition and multiplication.

How to Skip-Count by Fives

  1. Start with Five: We start at 5.
  2. Add Five Each Time: Each time we skip-count, we add five.
    • So, after 5, we say 10 (5 + 5).
    • Then we say 15 (10 + 5).
    • Next is 20 (15 + 5).
  3. Keep Going: We can keep counting. So it goes like this:
    • 5, 10, 15, 20, 25, 30…

Let’s Practice!

Examples of Skip-Counting by Fives:

  • If you have 5 apples and you buy 5 more, you would have 10 apples.
  • If you have 20 stickers and you get 5 more, now you have 25 stickers.
  • Imagine you have 35 marbles, and then you find 5 more. Now you have 40 marbles!

Tips and Tricks

  • Use Your Fingers: Try holding up fingers to count. Each finger can represent a group of five.
  • Visual Aids: You can draw or use objects like blocks or coins to group into fives.
  • Practice with Songs: There are fun songs that skip-count by fives. Singing them can help you remember!
