About This Lesson
One of a set of three TESiboard Marble activities based on Ratio and Proportion. This activity relates ratio and proportion to fractions, requiring the boxes to be labelled with the correct fraction representation. It will accept fractions that aren't the most simple but then will prompt for a simpler version. The expert level requires the ratio to be applied up to larger numbers of marbles. The complete TESiboard set includes Marble Packing, Marble Checking and Marble Ratios which links ratio and proportion to fractions.
