This is a great idea to organize the differences and relationships between fractions, decimals, and percents! I think I could definitely use this in the classroom even with my fourth graders once they get a better handle on the conversion between fractions, decimals, and percents.I'm not sure if this was meant as review or an introduction, but it might have been better to use more scaffolding, like showing all the steps to get to each fraction/percent/decimals. I would have also benefitted from more pictures. I know from my past experience, it really helps to show me an image to remember fractions. There are some good visuals that also convey the percentage that is colored in. This would really help as a UDL principle. Bolding or using text features would have made vocabulary and important information stand out.
Just a couple suggestions, I'm am not sure if all of the arrows were linked right, at one point it took me to an answers page before I had even viewed the questions. I also could not get the sounds to work when I clicked on the speaker.
