Equal shares — halves and quarters
Can do: Splits a shape or a set into two or four equal parts and names them halves and fourths.
Why it matters
It is the foundation of fractions, and the word that matters is *equal*. Children who miss that word spend Grade 3 confused about why 1/2 isn't just "one piece".
What it looks like when it's wobbly
Cuts a sandwich into two very unequal pieces and calls both halves.
⏱️ Two-minute check
Draw a rectangle. "Split it into four equal parts. What's each one called?"
Solid looks like: Four genuinely equal parts, and the word quarter or fourth.

Fair Shares at Snack Time
- 1Ask them to share it fairly between two people, then between four.
- 2Every time, ask the same question: "Is that fair? How do you know?"
- 3Fold a paper strip in half, then half again, and open it up to count the parts.
- 4Show a deliberately unequal cut and ask whether it's a half. Insist on the word equal.
- 5Split a set as well as a shape: eight grapes between four people.
If it's too hard
Halves only, with things that fold or snap in the middle.
If it's too easy
Split into thirds, which is genuinely hard, and compare a half to a quarter to see which is bigger.
Say this
"Halves have to be equal. If one piece is bigger, they're just pieces — not halves."
