A FULL LESSON on estimation.

Assumed prior knowledge:

• BIDMAS
• Percentages of amounts
• Rounding with significant figures and decimals.

We are learning about: Estimation by rounding.
We are learning to: Use estimation to solve real world problems.

Differentiated objectives:

• Developing learners will be able to round to a given number of decimal places or significant figures.
• Secure learners will be able to estimate outcomes using significant figures.
• Excelling learners will be able to apply their understanding of estimation to solve real world problems.

Starter: Rounding spider (Inspired by alutwyche)
Main: Numerical, following into contextualised, problems. (First problem inspired by DanWalker)
Plenary: Fermi estimation style question.
