A fun maths and estimation activity where every answer must be given in standard form.

• Writing number in standard form
• Solving quadratics

The lesson presentation will guide the activity.

1. Distribute one copy of the pupil sheet to each pupil, or to pairs.

2. Play the explanation video (slide 2 of presentation) to pupils.

3. Answers are given as you go through presentation rather than at the end. Therefore, I suggest imposing a time limit for pupils to write their answer after each question.
