We have Everday Graces as well. We’ll try the intermediate level of Etiquette Factory – I really liked the sample for that and the child reads it themselves (no silly songs or videos at that level). As a family we’re reading Manners Made Easy – not my favorite. I have to do lots more explaining and sometimes out and out disagreeing. It’s also written in a format that’s not very kid friendly. In the past we’ve used the Hidden Curriculum calendar (or iApp). It’s a great one for teaching the ‘unspoken’ aspects of manners. 365 Manners Kids Should Know looks good, but it is written to the parent, not the child so if you’re looking for something they can do themselves, this wouldn’t work.
I have two boys around this age (12 and 11) and we’ll be hitting personal hygiene as well as manners!
