Rounding to significant figures and estimating
This is a full lesson based on 80 mins but could be changed for your lesson length. It starts with a settling starter of place value questions arranging cards followed by the learning objectives slide. The main starter is a rounding activity with decimals from the previous lesson. The examples go through how to round to significant figures and use that for estimation and notes for students to copy into their books. There is a slide of differentiated questions and the extra practice activity is a treasure hunt. The plenary is an exit ticket that is in a word document so can be easily printed
