I purchased my template from Busy Teacher's Cafe several years ago. I just checked it out, & no longer see my template, but there are others you may be interested in.
I always include all the skills we are learning for the week in all subjects, as well as the week's spelling words. I have to blocks of space in which I can include notes of interest for parents, updates, needs, & wishlists, etc. There's also a space where I type in school events.
SO-- what does your newsletter look like, & what do you include?
Link up & let us know!
