One of the best places to find additional teaching resources is previously used kit items. The best part of this is that are free! Many times I can find things to repurpose for Bible Skill activities.
For example, here are a few items I saved from LifeWay’s Submerged material after we did VBS at our church:
Memory Verse posters:
-John 3:16 – Green Cycle Children’s Bible Drill (current cycle)
-Luke 19:10 – Blue Cycle Children’s Bible Drill
-1 John 4:19 – Red Cycle Children’s Bible Drill
-Psalm 139:14 – Youth Bible Drill – Cycle 2
-Psalm 139:23-24 – Youth Bible Drill – Cycle 3 (current cycle)
