How tall is the Eiffel Tower?

How to use this board

Put one question on the screen. Pupils talk. Nobody needs the “right” number first.

• Talk prompts — what facts do we already know?
• Sensible estimate — a range and a sample way to think, not the only method.
• Two cards are talk-it-through questions (coins in the classroom, and a line of pupils to France or the Moon).
• A new question is added every day at 10:00 UK time.
