Here are some ideas to help with memorizing scripture. It's the most important part of schooling our children, and there is no reason why it shouldn't be fun. :)
Here we worked on memorizing Romans Chapter 6. We drew pictures for each chapter which included a few words to help jog the memory. When we were done we put them in a folder with page protectors.
For Christmas one year, we made a bunch of these books to give as gifts. This was a fun family project. We all drew pictures to represent a Proverb. So on the 3rd day of the month you would read Proverbs chapter 3, and then holding up the picture, you would try to guess which verse in Proverbs the picture represented. The book has thirty-one pictures, one for each day of the month.
This is a picture of a poster Ben and Jonny made. They drew pictures and pasted on art to help them remember the story of the Lost Son, which is a parable in Luke 15.
More recently we have been doing lap books. If you are a homeschooling mom, you are probably familiar with lap books. They are a very fun way to learn about a subject! They turn schoolwork into an art project! Here's a picture of one we did on Psalms 24. I just printed off a bunch of clip art pictures from my computer and we added the verses...and some glitter glue - easy! :)
Our current project is "Building on the Rock", Matthew 7: 21-29. We are making a book and will be painting pictures to represent the verses.
Here are some good resources if you need ideas.
