3.NF.3. Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
Match Fractions Decimals and Percentages
Match the equivalent fractions, decimals and percentages. Alternatively, you can choose to convert between just fractions and decimals, or between fractions and percentages or decimals and percentages. Diagrams to show equivalence can be turned on or off.
This ITP has been remade so that it will work in modern browsers. It will remain free to use.
This ITP allows you to divide a green strip into a number of equal parts and colour the individual parts in yellow. You can label the strip to show what proportion the coloured yellow parts are of the whole strip. This can be shown as a vulgar fraction, decimal (to 3 decimal places) or percentage. The ratio of yellow to green can also be displayed. You can create more then one strip and drag these up and down the screen to compare strips.
The ITP can be used to explore equivalence between fractions, decimals and percentages and the different representations of the same relative quantities. The equal parts on the strips can also be used to demonstrate how to calculate fractions and percentages of given amounts and to represent a horizontal bar chart. The ITP can be used to set up and solve ratio and proportion problems.
