My husband went to one of those big warehouse sales (Everything Must Go! Lowest Prices in Town, One Weekend Only, blah,blah) and bought some lesson planner software for $3.
It looks pretty good because it has a grade keeper and two extra discs with school fonts (you can use these for handwriting practice, etc.)
The best part is that it was marked down from $116.43!
It’s available used on Amazon for $2.97 US if you want one too. It’s compatible with Windows and Mac.
