# Fraction fiddle: matching cake fractions

TLF ID L2801

Fill orders in a cake shop. Match a fraction to parts of a cake. For example, identify the fraction of a cake remaining after it has had one quarter removed. Check your prediction by making the fraction and seeing what it looks like as part of a circle. Watch the circle change as you adjust the numerals in the numerator and denominator of the fraction. This learning object is one in a series of seven objects.
