What counting is
Introduce the idea. Luna opens with the objects visual — a row of countable objects; counted-so-far light up one by one, with a running numeral. The counting/addition staple, across 1 narrated beat, so the concept is seen before it is ever practised.
What Luna says
- Counting is how we find out how many. Let's count these apples together!

Count to 5
Worked example. Luna walks one case step by step with the objects view — a row of countable objects; counted-so-far light up one by one, with a running numeral. The counting/addition staple, turning the idea into a procedure a child can repeat.

- One.
- Two.

Compare
Introduce the idea. Luna opens with the compare visual — two groups of objects with a < > = "hungry mouth" sign that eats the bigger amount, across 3 narrated beats, so the concept is seen before it is ever practised.
What Luna says
- Sometimes we want to know which group has more. Let's compare two plates of cookies!
- This plate has three cookies. This one has five.
- Five is more than three — see how this side is taller?

The sign
Worked example. Luna walks one case step by step with the compare view — two groups of objects with a < > = "hungry mouth" sign that eats the bigger amount, turning the idea into a procedure a child can repeat.
What Luna says
- We show it with this sign. Think of it as a hungry mouth that always opens to eat the bigger number. Chomp!
- So three is less than five.
