4/4 time measure to train kids how to read time and music

My sister is a music teacher and she wanted a way to make it easier to teach kids how to clap a beet and so we make these notes that are sixteenth notes, eighth notes, quarter notes, half notes and whole notes. I also mad a half/hole rest along with a quarter rest. Please let me know what you think of them and I hope to help teachers make music fun by having them clap out the beet.
