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.
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'.
"The word on the street is that Fraction Jackson is a dog
who loves pie (pi?). If you answer 24 problems correctly, you can put your name
on Jackson's list of Master Pie Bakers"
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.
There are five levels to work through. In level 1 you simply type in the number of children to share the pizza and the pizza will be cut into fractions for you. At Level 2 you drag fractions to complete a fraction wall. In Level 3 you have to count the number of shaded squares and the total number of squares then type in the fraction (use a slash e.g. 1/4). Level 4 introduces a fraction numberline for you to drag the fractions onto. Level 5 uses a pizza to illustrate fraction equivalences.
In this game from Count On you practise finding a fraction of a number. You can play it as a two-player game or a single player can play against the computer.
A fraction is shown on the screen and you have to decide whether it is more than a half, the same as a half or less than a half and click the correct button. You have to be quick though otherwise you will miss your chance to answer the question.
You can choose from easy or hard levels. The aim of the game is to compare the fractions and click on the one with the highest value. In the easy level you have four to choose from, but in the harder level you have six fractions to choose from
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.
