This is a simple card sort activity where students fill in the blanks, practising converting between fractions, decimals and percentages and then placing them in order from smallest to largest.
What I particularly like about it is that you can hand out the cards in 3 sets of 5. This could provide differentiation, but more importantly (in my view) it gives the teacher the chance to assess the progress of the students as they go. It’s easy to glance at Set A to see if they have worked it out.
As you circulate the class, helping students you can give out Set B which interleave with Set A to produce this:
And then finally with Set C, you get this:
Here is the pdf as a set of 15 cards, but if you are printing a class set, then I strongly recommend using the Excel version here. This is set up so you print 5 at a time. They come out stacked so that as you cut you have a set of 5 already in a pile without needing to sort them.
Also, if you want to change the actual values and which values you show, you can do that on the spreadsheet too.
