When I taught the children, we did a quick version.
- ONE God-no others
- His Name is Holy
- Keep Sabbath Holy
- Honour your father and mother
- No murder
- No adultery
- No stealing
- No false witness
- Don't covet neighbours wife (spouse)
- Don't covet neighbours goods.
I split them into the first three are about God and right worship; 4 is about family and Church and 5-10 are about family and community.
After they had learned them we could do some Catechism.
It's made it easier for me to remember them anyway.
