#### Frequency trees and Probability Yr10

(0)
Quick lesson pitched for a low ability set 6 Maths class. FDP equivalence starter with a demonstration by me before students attempt minimally different questions after. Go through working out missing values in the frequency trees before moving onto some probability calculations and finally add in some elements of relative frequency and expected outcomes, hoping to drill in the law of large numbers,etc. Scaffolded through out trying to get them to use fraction buttons on their calculators etc and leaving hints to help those struggling. Answers included but will need some teaching/boardwork
