Maths week 7 term 3 2019

For this weeks maths it we did not really have a topic like adding,decimal,take away or anything else it was pretty random but first we went on Countdown and look at some things and their price to add it up to $30.00 and I got exactly $30.00.  For task 2 we recreate a strategy from a number talk and if you don't know what a number talk it is just a quick activity we do before getting in to are maths tasks.  Also lucky last in task 3 we did a decimals minus question you can't really see it properly but it say to show a diagram how you worked it,another way to solve this,A story problem I have written and 10 other similar questions.
