Today you will practice converting between fractions, decimals and percentages by conducting an investigation of random colours.

You will work in pairs, each pair will need 4 different coloured shapes. Create a table like the example below in maths book.

You will work in pairs, each pair will need 4 different coloured shapes. Create a table like the example below in maths book.

One student (with eyes closed) selects a coloured shape.

One of the pair records the tally on your chart while the other student rearranges the order of shapes.

You will need to select the counters 25 times.

Complete all parts of the table above, and then answer the questions below.

What percentage of shapes selected were red?

What percentage of shapes selected were green?

Were more than 20% of the shapes selected blue?

What was the highest percentage of shapes chosen?
