Math trading with Pocky

It was Jae & El’s birthday recently and we bought some boxes of Pocky.

These are popular cream-coated biscuit sticks from Japan.

El chose the almond sticks, which come in 2 packs of 7 sticks in a box.

Jae chose the chocolate sticks, which come in 2 packs of 25 sticks in a box.

They tried to work out a fair trade.

💡 How many of Jae’s chocolate sticks should be exchanged for each of El’s almond sticks so that it is as fair as possible?

After discussing, the boys struck a deal that both parties are happy with.

This is how we do high-order thinking math without drills.
