It took a few weeks, but I've compiled all 13 of the lessons, worksheets, and review games into one 90 page download! If you homeschool, teach a group of kids at church or just want an in-depth family devotional to do, I recommend taking a look at the God's Big Picture curriculum. It's designed for 3rd-6th graders, but I think it would be appropriate for many middle-schoolers as well.
I'm sure the packet will need some tweaking over time. If you find any typos or mistakes or have any feedback for me, please leave a comment below and I will try to periodically update the material!
Here's the link to download your packet!
