Delicious Decimal Fractions



This afternoon we had a tasty maths lesson about decimal fractions. First we talked about how important fractions are to us when we are cooking and working out serving sizes. Then I cut the cake into ten equal pieces. I measured the cake to make sure this was exact, although if we had scaled we could have weighed the pieces to check that they were all even. We discussed the difference between cutting ten slices and cutting ten tenths, as each tenth must be the same size.


We then talked about each slice being one tenth (1/10) or 0.1 of the whole cake. If we had four slices we would have 4/10 or 0.4 of a cake. We also discussed cutting the tenths into ten again to make hundredths (1/100 or 0.01). This reminded us how small hundredths are and that we wouldn't want to eat 0.01 of a small cake like this! After doing some addition and subtraction problems with tenths we all enjoyed our delicious 0.1 slices!
