# Opposite Faces of a Dice

Learning video 82 · Geometry · Grade 4 · 0:34

## Read the story

Take a close look at a dice.

The dots on opposite faces always add up to 7.

The 1 is on top, so the 6 is on the bottom. Because 1 plus 6 is 7.

The 2 is in front, the 5 is at the back. 2 plus 5 is 7 too.

**The 3 is on top. Which number is on the bottom?**

## Answer and working

Correct! 3 plus 4 is 7. The 4 is on the bottom.

`7 − 3 = 4`
