Thankyou for visiting my website. Feel free to go through the maths quizzes and activities. If you have any questions you can email


This website was designed to meet the needs of grades 5 and 6 students and aims to assist students in theirs studies of mathematics. This website aims to facilitate the students understanding of mathematic concepts and endeavours to enhance their maths skills, in an interactive and stimulative approach.


This website aims for students to achieve the following CSFII Level 4 outcomes and indicators





Use place-value knowledge to read, write and order negative whole numbers and decimal numbers from thousandths to millions.

- compare and order decimal fractions with unequal numbers of places (e.g. 3.05, 3.001, 4.4, 3.12)

- represent the structure of whole numbers to 7 digits and decimal numbers to 3 decimal places

- count in decimal fractional amounts


Compare and order common fractions

- compare and order common fractions with related denominators


Rename common fractions as decimals and percentages.

- convert a simple common fraction to a decimal and vice versa

- convert a simple common fraction to a percentage and vice versa


Recall automatically basic multiplication and division facts, simple common fraction facts and frequently used common fraction, decimal and percentage equivalences

- automatically recall and use multiplication and division facts up to 10 10

- automatically recall and use simple common fraction addition and subtraction facts

- automatically recall frequently used common fraction, decimal and percentage equivalences


Use estimation strategies to check the results of written or calculator computations.

- use front-end estimation to check computations

- round decimals to the nearest whole number to check a computation


Use written methods to add and subtract decimal numbers.

- add and subtract decimal numbers with equal numbers of decimal places without using a calculator


Use models to illustrate the four operations with common fractions, and develop written methods for carrying out these operations.

- add and subtract fractions with small related denominators (e.g. fifths and tenths) and record these using understood written methods

- use appropriate models to represent products and quotients of simple fractions (e.g. half of half a pie, how many half pizzas in three pizzas?)

- find fractional parts of discrete collections and quantities


Analyse a problem situation which may involve several different operations, decimal numbers, negative whole numbers and common fractions; express the problem symbolically and choose appropriate computational methods to solve it.

- select the relevant information to solve a problem or carry out a practical task and determine whether additional information is required

- restate verbally expressed problems symbolically in terms of the operation needed

- describe situations which may be represented by given symbolically expressed number sentences


Generate and investigate number sequences which may involve fractions, decimals and combinations of operations, using a calculator where appropriate.

- describe and verify rules for number sequences which relate each element to the previous element or elements (e.g. next term in a Fibonacci sequence) and each element to its position in the sequence (e.g. tenth term of 1, 4, 9, 16, 25, ).


Choose attributes and standard units appropriate to the task.

- select the appropriate unit to specify a quantity (e.g. height of a building, area of a football ground, capacity of a storage tank)


Measure and compare the perimeter and area of regular and irregular polygons.


- see the need for perimeter in practical situations and calculate it by adding lengths

- devise and use own short cuts for finding the perimeter of polygons (e.g. multiply by 5 the length of one side of a regular pentagon; add adjacent sides of a rectangle and multiply by 2)


Investigate the relationship between area and perimeter and calculate the area of a polygon.

- systematically investigate areas of rectangles in square units, and generalise that a shortcut method for finding area is to multiply the number in each row by the number of rows (e.g. rectangles of 12 or 36 square units)


Compare, order and summarise data sets using simple numerical methods.

- use simple fractions, decimal fractions and percentages to summarise data (e.g. 22% of Year 5 students ride a bike to school)

- find the lowest and highest values of a data set

- find the middle score, median or scores by ordering a data set

- calculate the mean and find the mode of a data set.


Extract and interpret numerical information contained in tables, data displays and databases.

- compare summary statistics between and within data sets (e.g. mean heights of boys and girls)


Use and interpret simple mathematical models.

- use multiplicative models when measuring and estimating (e.g. when finding the perimeter of polygons, areas of rectangles, interpreting percentages or estimating the number of seats set out in a school hall for a parent meeting)
