💡 Nhiều, ít, bằng — Fun Facts

The equals sign is two lines that are exactly the same length.

A man named Robert Recorde invented it long ago. He picked two matching lines because nothing is more equal than that!

The 'greater than' sign is like a hungry mouth for the bigger number.

The wide open side always points to the bigger amount, as if it wants to gobble it up. So 5 > 3 means 5 is greater than 3.

Two groups can look different but still be equal.

Four big blocks and four tiny beads are still equal, because both groups have 4. It is the number that counts, not the size!

The equals sign (=) means both sides are the same.

When you write 2 + 2 = 4, the = tells you both sides are worth the same amount. It is like a little balance.

You can see which group has more by matching them one to one.

Line up the cups and the spoons in pairs. Whichever line has a leftover has more, and the other has less.

'Equal' means two groups have the same number of things.

If you have 3 stickers and your friend has 3 stickers, your groups are equal. Nobody has more or less!

'More' means a bigger amount and 'less' means a smaller amount.

If you have 5 grapes and your friend has 2, you have more and your friend has less. Comparing tells us who has the bigger group.
