Hi. I'm looking for my kids the best - top books to a more school subjects. Now my kids are sitting at home and online lesson sometimes look like fun and something what kids have to do but don't want. I prefer have some very good book for example of history or geography and slowly step by step, topic by topic read it with my kids. I've checked few revision books which are on the market but it is look like not everything is there. Very often we read some topic for example about rivers or about one king and after we try make test about it and there were a lot of question make us problem. It was look like the books doesn't tell us everything what my kids should know about this topic. Any very good books which covered more or all secondary education program? Thanks a lot.
