# fractions

## Pirate Swords

Solve problems involving halves,quarters and thirds

Devise and use problem solving strategies to explore situations mathematically.

## Netball Goals

Find a ¼ and ¾ of a set.

## Sandwiches

Divide a region into two equal parts through folding or cutting

Demonstrate that the two parts are equal and describe these parts as halves

## Three Circles I

In this unit students are asked to investigate mathematical relationships when they select various numbers into be used in 3 circle configuration below and in 6 circle configurations. They will explore both whole number and fractional numbers as they consider how various configurations impact on the relationships between numbers.

## Fraction Bits and Parts

This unit explores the beginnings of proportional thinking by introducing fractions. The purpose for this unit is to make, name, and recognise wholes, halves, third parts, fourth parts and fifth parts of a variety of objects. The use of two different physical representation, the whole and parts of a whole is used to develop the concept of fraction. Language plays an important part in this unit. Being able to count in fractions helps the children to see that you can have 5 thirds or six halves. Although the unit is planned around 5 sessions it can be extended over a longer period of time.

This unit supports teaching and learning activities in the Student Fractions e-ako 1 and 2 and complements the learning activities in Book 7 Teaching Fractions, Decimals and Percentages.

This is the first in a series of units developing fractional understanding. The units that follow are:

## This is to That

In this unit we look at ratio, what it means for numbers or objects to be in a given ratio, and how ratios and fractions are related.

## Getting Partial

In this unit we explore fractions of regions as well as fractions of sets.    We look for and understand the connection between fractions and division.

## The Painting Triplets

Form and solve linear equations

Devise and use problem solving strategies to explore situations mathematically (be systematic, use algebra)

## Flip's Flag

apply the angle properties of squares, rectangles and triangles

use fractions to express the relationships between the areas of rectangles, squares and triangles

devise and use problem solving strategies to explore situations mathematically (be systematic).

## Fraction Dominoes

This activity provides students with a fun, game context in which to practice their equivalent fraction skills.
