I like to work on chunks of Bible memory rather than a verse or two at a time. Currently my first graders are learning Psalm 100. I attempt to have them say it chorally twice a day–during our opening exercises, and just before we go home. We do use motion to go with it. Some years, motions have been a big key to student memory and students came up with all kinds of motions for all kinds of things.
We learn a passage nearly every month. It depends on the class because we work on one passage until I think they know it well and then we move onto the next one.
I send a paper home with the passage when we start learning it. Parents are requested to go over with their child at least once a day–some do better than others.
I also like to go over the passage with the students and give them some idea what they are saying especially since we memorize from KJV. One year I had various amusing recitations of The Lord’s Prayer. It was obvious the students had no idea what the words really were or what they meant; a learning point for me.
