The big ideaWhen something happens again and again, it repeats. A loop says it once.
How it works
When something happens again and again, it repeats.
The swing, the seesaw, a ball and a drum all repeat.
A loop says it once, and says how many times. Some things happen only once, like a leaf falling.
Repeats, or just once.
Example 1: The swing
Mia gives the swing a push.
It goes forward, then back, then forward, then back.
Forward and back, again and again.
Example 2: A beat
Mia claps clap, clap, stomp, clap, clap, stomp.
The same beat happens again and again.
The short way to say it is clap, clap, stomp, three times.
Example 3: Just once
Bo slides down the slide one time.
Now he is at the bottom.
Sliding down once is not a repeat.
Example 4: Days repeat
The sun goes up and comes down, then it comes up again.
Morning, night, morning, night.
Even the days repeat.
Words to know
repeat
To happen again and again.
loop
Saying a repeat once, and how many times.
once
Just one time.
again
One more time.
Watch out
Something that happens only once does not repeat, even if it is fun.
A bench just sits. If nothing moves again and again, nothing repeats.
A swing slows down in the end, but it does go again and again for a while.
Try it
Does a ticking clock repeat?
Does a falling leaf happen again and again?
The swing goes forward and back. Does it repeat?
Which happens just one time: a sneeze, or waves on a beach?
Answers: 1. yes · 2. no · 3. yes · 4. a sneeze
Try at homeWalk around your home with a grown-up and find three things that repeat. A clock ticking, a tap dripping, a fan turning or the steps on a staircase all count. Say each one in a short sentence, like "The fan goes round and round."
