Fractions

Room 13 has been exploring the beginnings of proportional thinking by introducing fractions and associated symbols and language. 

The purpose for this is to make, name and recognise wholes, halves, thirds, fifths, and tenth parts of a variety of objects. The concepts that we have been developing with the children are that there is a whole of an object, part of an object and the idea of fair sharing.

The aim is for students to also know the symbols for ½, ⅓, ¼, ⅕,1/10, and relate these to an object with the same amount of pieces. We are also using real-life situations to support students to make links between everyday objects and situations.

Room 13 folded and made 3D pizza shapes

and put all the pieces together to make a 10 piece pizza.  

There are three different colours that have been created by the students.

From these pizzas, students manipulated them to work out different fractions.

The use of word problems gave students real-life context to solve these fraction problems.  

Problem-solving

Students are given a word problem to solve using the pizza pieces. 

Example: 

  1. There are 8 marbles and Danial wants to give half to his friend Sam.  How many will he give to his friend?

  4. There are 9 pieces of pizza.  If we gave a third to Fred how many would he get?

Further word problems related to 1 quarter of eight, 1 fifth, and 1 tenth. 

Reid: I have learnt how to make ⅓, ⅕, and 1/10.  I enjoyed making our 3D pizza shapes and I have learnt that fractions are different from one another.

Hector: I learnt how to share equally to find the answer to a word problem.

Oscar: I learnt about different fractions and I also learnt how to write the symbol for each fraction.  I now know what the shaded part of a shape is called.
