Kavi's Fair-Share Picnic 🧺
Kavi brings 8 cookies 🍪 to the picnic to split fairly with one friend. "8 is even," thinks Kavi, "so we each get 4 — nobody misses out!" Then 7 ducklings 🦆 waddle up to dance in pairs. "7 is odd," says Kavi, "so one duckling will have no partner." Kavi can tell if a share or a pairing will work before even trying — just by asking: is it odd or even?

What your child will learn
1Count in twos — these are the pairsHop along the line in twos: 0 → 2 → 4 → 6 … Each hop of 2 is one whole pair. The numbers you land on — 2, 4, 6, 8, 10 — are the even numbers.
2The even-number trackHere is the even-number track from 2 to 20. The bright numbers are even — they pair up and share fairly between two. For any number, big or small, just peek at its last digit.
3Will everyone find a partner?To pair up, each one needs a buddy. Tap the pairs and count in twos with Kavi. If nobody is left over, the number is even — the pairing works!
4Share fairly between twoSharing between 2 is the same question as making pairs. Tap Add 2 to drop one counter in each of two hands. If the counters fill in perfect twos with none left over, you can share it fairly.

A peek inside
Kavi has 8 cookies 🍪 to share fairly with 1 friend (that's 2 people). Will it work? How many each?
8 is even → 8 = 4 + 4
Try this at home: Can 6 apples 🍎 be shared fairly between 2 plates? How many on each?
