I made these 2 w/sheets for my nurseries here in Japan.
Page 1 is for the older nursery kids (nensho nenchu nencho). It includes capital letter tracing, and 1 picture to color in (the title can also be colored in, to facilitate letter shape retention).
Page 2 is for the 3 year olds, it has less letters to trace. Only single occurrences of letters are to be traced on this page.
These may be useful for your young learners.
P.S. I'll have a second worksheet to follow on from these made soon, so keep an eye out if you're keen for more.
