grammar series

[pigpokey]

I'm looking for an easy to implement grammar series appropriate for third graders that continues through many academic years.

I prefer consumable or software that can be done for about twenty minutes per school day and offers sufficient practice for mastery.

Any suggestions?

For an idea of what already works for us, we do Rosetta Stone, Getty-Dubay, JUMP at Home, Times/Division fact drills with Timez Attack, Typing Instructor for Kids ...

We've been using Easy Grammar, and I do truly find it easy.  We do a little bit each day; it doesn't take long, and yet reinforces basic concepts.  So far we've done the grade 2 & 4.  I plan to continue it next year.
