This link to an article on Wikipedia "Hexadecimal" will start you off. The table near the top the article sets out the codes for 4 bits of data which covers 0 to 15. I am sure someone will else be along shortly to point you at a more complete table.
If you (or your kids) happen to have a scientific calculator, there's a chance that it has a Hex mode. If it does, you could use this in conjunction with the Wiki article to do the conversions.
When I am working with bits as you are for CVs, I actually find it easier to work in Hex. I write out the settings I want and then convert the groups of 4 bits to hex. It seems more natural to me than adding 128 to a value just to set bit 7.
