WALT understand division of fractions by whole numbers in 21/04/20 context. XXI/IV/MMXX
4 Let s imagine I have half a cupcake that I want to share between 4 people. Model this calculation on a strip of paper like in yesterday s lesson. How can we share half of something into 4 equal groups?
3 If I share half equally into 3 groups, how many in each group? I see that it is one of six sections, so 1 2 3 is 1 6
DO YOU NOTICE A PATTERN BETWEEN THE FRACTION, THE WHOLE NUMBER AND THE RESULT? 1 2 4 = 1 8 1 2 3 = 1 6
There was half of a rectangular cake left after the school fete. Four teachers decided to share it equally, what fraction of the original cake did each teacher receive? Nicola shared one quarter of a litre of squash equally between 3 glasses. How much squash, in litres, was in each glass? HAVE A GO AT THESE Deborah has one third of a kilogram of peanuts. She wants to share them equally between 5 friends. How many kilograms of peanuts will each person receive? Create a word problem for 15 4.
