Start with bismillah.

Measure a table with your hand-spans, then let an adult measure it with theirs. Ask: "Why did we get different answers?"

Watch the TED-Ed video "Why the metric system matters".

Now listen to the ayah together in the app, with the translation. Ask: "What do these people do when they are receiving?"

Each child keeps one wonder question, for example: "Why do people want more for themselves?" Younger children can draw theirs.

Find it in the mushaf: Surah Al-Mutaffifin is surah 83. Find ayah 2. The key word yastawfun means they demand the full amount. They are very careful when it's for them.

Fact: Why did the world agree on units like the metre and the kilogram?

Ages 5–8: Cup test. Fill a cup with rice using a spoon, counting spoons. Now try a bigger spoon. Why do we need the same spoon every time?

Ages 9–12: Units history. Find out about old units like the cubit and the foot. Why did they cause arguments?

Finish with: "I found that we need standard units because ___."

Talk together:

• Is it wrong to want your fair share? When does it become unfair?
• Which name of Allah does this remind you of?
• Why do people sometimes measure carefully for themselves but not for others?
• How can we be as careful for others as we are for ourselves?
• What does fairness look like in your family?

Make a small plan: "This week, I will give others the same amount I would want for myself."

• Pour drinks or serve food fairly for everyone.
• Show someone your spoon test.
• Tell someone why the world uses the same units.
• Next time: the next ayah (83:3) says what cheaters do when they give. Explore it together!

Action: Give others the same amount you would want for yourself.
