Kavi Shares the Berries 🫐
Kavi has 8 berries 🫐 and 4 hungry friends. "To give each friend a fair share, I share them into 4 equal groups," hoots Kavi. "One group is a quarter — that's 1/4 of 8, which is 2 berries!" Kavi grins, "To find a unit fraction of a set, share it into equal groups and take just one group."

What your child will learn
1Share into equal groupsHere are 8 berries 🫐 in 4 equal groups — 2 berries in each group. Tap to count them: 2 + 2 + 2 + 2 = 8. To find 1/4 of 8, take just one group.
2Share a quantity into equal hopsTo find 1/3 of 12, share 12 into 3 equal groups. Each hop here is one equal group: start at 0 and hop +4 — 4, 8, 12 — that's 3 equal groups of 4.
3One group = one part = a unit fractionA unit fraction has 1 on top: 1/2, 1/3, 1/4. The bottom number is how many equal groups you share into. This whole is split into 3 equal parts — tap one part to shade 1/3, just like taking one group of a set.
4Count the groups, take oneNo pictures now — just share by skip counting. Count by 3 up to 12: 3, 6, 9, 12. That is 4 equal groups of 3, so 1/4 of 12 = 3 — one group.
