I love finding great resources, especially free ones.
When my kids were younger I made a Youtube playlist of spelling and phonics videos from The Electric Company and Between the Lions. The videos teach spelling patterns and rules. I find that the catchy tunes really help cement some concepts. When my kids were younger I would put the videos on several times per month while my kids were eating lunch.
Click here to see a playlist I have set up. It covers topics like -tion, silent e, n’t, and much more.
Here is another playlist I found with more than 100 spelling and phonics videos!
