Test your knowledge of percentages and their relationship with proper fractions. Represent given percentages on a 5 by 5 grid. Also show them on a number line marked in tenths. Allocate squares on the grid to match the given percentages for different parts of the park. For example, show 24% of the grid as bushland. Add each percentage to the number line by moving a bar along the line. View and print a report of your results. This assessment object is the last in a series of three objects that progressively increase in difficulty.

A good game for negative numbers and mathematical thinking. This game is for two players - you can use the interactivity below, or you could draw a number line on a piece of paper and find a counter to use. In both cases, you will need two dice. Decide who is Positive and who is Negative. Positive moves from left to right and Negative moves from right to left. Take it in turns to throw the two dice and add the scores then move that number of places in your direction. If the counter reaches −13, Negative has won. If the counter reaches 13, Positive has won.

Explore ways of representing decimals using mathematical notation and visual tools. Match a decimal fraction between 0 and 1 such as 0.7. Adjust units on a range of visual scales and other representations. Work with a random selection of two of these representations: common fraction, number line, counting frame, dial, array and pie chart. Match at least three decimals with each tool. This learning object is one in a series of nine objects.

a Flash based website with interactive manipulatives that students and teachers can use to introduce or reinforce maths concepts. It is suitable for students from Kindergarten to Year Eight. This site is very simple to use (mostly drag and drop) and requires very little preparation. You simply choose a background from the collection of Game Boards, Story Boards or Work Mats. Work Mat options include place value mats, tens frames, graph paper, algebra tiles, in and out equation tables, blank calendars, number lines and number charts.

Help a town planner to design a site plan for a school. Using a 10x10 grid, design areas for four regions (library, car park, lawn and canteen) based on the percentages given. Assign the area for an additional two regions, using percentages of your choice. Use a number line to indicate the equivalent fractions for two regions. This learning object is one in a series of two objects. The series is also packaged as a combined learning object.

Help a girl to throw her ball through a hoop. Build two fractions to make a total of one whole. Complete the denominator of a fraction (at least one fraction may have a fixed numerator). For example, work out how many tenths can be added to three-fifths to total one whole. Look at fraction bars and a number line to compare the two fractions and their total. This learning object is one in a series of seven objects.

A great range of fraction games that progress from easy levels of creating fractions up to adding fractions and creating mixed numbers.

Use visual representations of two fractions to find a common denominator. Write the two fractions as equivalences with the common denominator. Place the fractions on a number line. Find new fractions between the two original fractions.

Help a town planner to design a site plan for a city. Assign regions on a 10x20 grid for different uses such as factories, hospitals or parks. Calculate the percentage and the fraction of the total site used for each region. Use a number line to display fractions and equivalent decimals. This learning object is one in a series of three objects combined as 'Neighbourhood fractions'.

Order the fractions on the number line (explores equivalent fractions)

FANTASTIC SITE for maths games - HEAPS of interactive maths games. Stop the Clock is great for time (varying levels), Power Lines is great for mathematical reasoning
