What is it?

A 'Group of Fours' simply means having four items or units collected together. It's a way to count and organize things by making sets of four. Think of it like putting four similar things into one small box.

Simple Example

Quick Example

Imagine you have many colourful bangles. If you put four bangles together on one wrist, you have a 'group of fours' bangles. If you put another four on the other wrist, that's another group of fours.

Worked Example

Step-by-Step

Let's say you have 12 ladoos and you want to put them into 'groups of fours' for your friends.

Step 1: Take the first four ladoos. This is your first group.

---

Step 2: You now have 12 - 4 = 8 ladoos left.

---

Step 3: Take another four ladoos from the remaining 8. This is your second group.

---

Step 4: You now have 8 - 4 = 4 ladoos left.

---

Step 5: Take the last four ladoos. This is your third group.

---

Step 6: You now have 4 - 4 = 0 ladoos left.

---

Answer: You can make 3 'groups of fours' from 12 ladoos.

Why It Matters

Understanding groups helps you count faster and understand multiplication and division easily. This skill is used by shopkeepers to count items, by architects to plan buildings, and even by scientists to organize data.

Common Mistakes

MISTAKE: Confusing 'groups of fours' with having four groups of something else (like four groups of two). | CORRECTION: 'Group of fours' means each group must contain exactly four items.

MISTAKE: Forgetting to count all items when forming groups, leaving some out. | CORRECTION: Always make sure every item is either in a group or accounted for as a remainder.

MISTAKE: Thinking that if you have fewer than four items left, you can still form a 'group of fours'. | CORRECTION: You can only form a 'group of fours' if you have at least four items available.
