This is a great challenging math assignment/project you can give your kids. It will really help reinforce the concepts of fraction / decimal / percent and how to recognize them in each form. 25 separate cards will be cut out and you will try to assemble it properly to solve it. There is only one correct answer but finding it will be a real challenge as certain pieces do fit in more than one place but will not work unless you find the exact correct place. There is also an extension activity at the end of the assignment which will be even more challenging than the puzzle itself. As a really good follow up activity, you can have students create their own puzzle after then have completed this one.
