Here you have a spreadsheet to use at the beginning and the end of the school year. On meet the teacher, have the parents fill out this information for their child. Lay out some measuring tools, so they will be able to measure their height. Get this information at the end of the year also. This is a great activity to do and put the information in a memory book for your students!
It was a huge hit with my parents this past school year! The parents enjoyed seeing how much their child grew in one school year. The students did as well.
