Fantastic Fractions

There is nothing like fractions to add a bit of real life learning into maths. Fair sharing is an everyday thing that all students do. Real life examples of how we use fractions include the sharing of food and the organisation of groups to play games.

Room 3, students have been gaining confidence in their fractions knowledge and understanding. We have set up a fractions wall display to help us compare fraction sizes and understand that fractions are a part of a whole. We have also created fractions fish - an art display of sea creatures that have been made by using different sized fractions of circles.  Some students have also developed their own faction problems for others to solve.

Fraction problem-solving 

After solving some of Mrs Sprague’s fraction word problems, Room 3’s Einstein maths group wrote their own fractions' word problems. The Einstein maths group is starting to make the connection between fractions and multiplication and division. Please beware, our fractions word problems seem to have a strong stealing theme.

Jackson had 100 lollies in a jar.  Briar asked if she could have ½ of the lollies.  How many lollies would Briar have? By Briar

Max had a huge bar of chocolate with 80 squares.  Finn came and stole ¼ of his bar of chocolate. How much chocolate did Max have left? By Finn 

Avery had 20 lollies.  She shares them with Alyssa, Molly and India.  How many lollies does each girl get and what fraction of the whole is this? By Avery

Grayson has 60 pounds of jelly.  He shared ⅕ of his Jelly to Aiden.  How much jelly did Aiden have? By Grayson

Reid had $50.  Layne stole ½ of his money.  How much money did Layne steal? By Reid

Ryker has 500 gumballs.  He shared them with 5 friends, so they each get ⅕ of the gumballs. How many gumballs do they each get? By Ryker

Jack has a 60 piece bar of chocolate.  Henry steals ½.  How much chocolate does Henry have? By Jack

Rikihana has 60 gumballs.  Asharntay stole ¼ of the gumballs.  How many did she steal?  By Rikihana

I know that to find a quarter, you have to half the half.  This works for a quarter of an object and a quarter of a set.   For example, half of 20 is 10 and then half of 10 is 5, so a quarter of 20 is 5.  Indigo

I know that the bigger the denominator, the smaller the piece.  ½  of pizza is more than 1/12. Ryker

I know that ½ and 2/4 are the same size. They are called equivalent fractions.  Equivalent means equal or the same.  Mason

A fraction that has the same denominator and numerator is actually a whole.  2/2 or two halves is actually a whole.  Jacob

An improper fraction means a fraction that is bigger than 1, like you might get 1 ⅓  pieces of pizza or 4/3 of pizza.  Rikihana
