About this sheet
One half, 0.5 and 50 percent are three ways to write the same amount, and fluent students move between them without thinking. Most children get there by knowing a handful of benchmark fractions well: halves, quarters, fifths, tenths and eighths. This chart lists eight of them, each with its fraction on the left and its decimal and percent on the right. The last row, one third, shows a decimal that never ends, which is a good prompt for discussion. Use the poster as a lookup while children practice conversions, then take it down for a quiz once the common ones stick. Every line can be changed, so you can add two thirds, or the sixths, when your class is ready.
Grades: 4 to 7.
How to use it
- Review the eight rows and decide which your class already knows, then edit any that need a different fraction.
- Print the poster and hang it beside the fraction strips and the hundreds grid, where children see the parts of a whole.
- Cover the right-hand column, ask for the decimal and percent of one fraction, and uncover it to check the answer.
Five ideas for class
- Shade 25 squares on a hundreds grid and ask for the fraction, the decimal and the percent, all written next to the shaded part.
- Connect to money: a quarter is 25 cents of a dollar, so one quarter is 0.25 and 25 percent, and children can say it three ways.
- Divide 1 by 3 on a calculator and look at the long string of threes, then discuss why the chart says about 33.3 percent.
- Play a matching game with cards showing a fraction, a decimal and a percent, and see which table can pair them all fastest.
- Ask students to explain a sale: if a shirt is a quarter off, how many percent is that, and what decimal would a shop use?

Questions
Why learn all three forms?
Each form fits a job. Fractions show parts of a whole, decimals work with a calculator and money, and percents compare amounts out of one hundred.
Why is one third a repeating decimal?
Dividing 1 by 3 leaves a remainder of 1 every time, so the threes never stop. We write about 33.3 percent, and a bar over the 3 shows it repeats.
Which fractions should children know by heart?
Halves, quarters, fifths, tenths and eighths are the usual benchmarks. They help children estimate and check answers on tests, shopping and cooking.
How do I save it as a PDF?
Choose Print, then pick “Save as PDF” as the printer. Only the sheet prints: the page around it is hidden. You can also save a sheet as a PNG image under the preview.
Can I print it in black and white?
Yes. Switch to Black and white beside the sheet: fills turn white and lines turn black, so it saves ink and photocopies cleanly.
