 G'day, I'm James and I'm so looking forward to coming up to Edmonton to talk about fractions and do you know what? Fractions are hard. They're actually really really hard So the sibling figure once for what a fraction is was the best thing we can do for our fabulous students to have deep learning deep Understanding and a deep intuitive field for what a fraction actually is Now of course we know this is the story that we start with fractions being a notion of a part of a hole Please circle two-thirds of the kittens. That's fine when you circle two-thirds of the kittens I'm going to great intuitive feel as a fraction is a part of a hole So I'll do a piece of the pie two for the supply one-third of a pie great So a fraction is just a cold action. It's not actually a number right there But then of course we want to do mathematics or during the curriculum You should start doing things with fractures like adding them and subtracting them and so on and then this gets a little bit shaky I mean maybe it makes sense to add pieces of pie some thinking parts of a hole addition Maybe make sense to bring those pieces together and they all got some more pie great But was it mean to multiply pieces of pie? It makes no sense So we change the model of what a fraction is as we go through in fact we go through the entire story curriculum story of fractions We keep changing the model of what we think a fraction is and we never actually say in the end by the way kiddos Here's what a fraction actually is after all this work. We've got all these different wayward models in all directions It just becomes a confusing confusing story. Let's wrap that story together together when I come up to Edmonton It's gonna be great So we'll talk about you know parts of a hole do all the you know Usual things about addition and multiplication and subtraction division of fractions We should play with ways to simplify mixed numbers. We'll play with percentages You know I get to talk about Egyptian fractions I will start to know that decimal representation of fractions and we end for a surprise because we know we've been told that not every number Is a fraction, but do you actually own an irrational number for yourself? Can you actually create your very own irrational number that you know for yourself personally truly is irrational? Well, let's do that today. Let's come up with your own personal irrational numbers by the end of the day as well So we'll just cover it all it's gonna be great It's gonna be fun and we'll just make sure this is a wonderful human connected story with deep understanding and deep intuitive joy All right, looking forward to seeing you then
