CGP workbooks - where to start...

[drspouse]

DS will do workbooks/homework with us but rarely does any actual work at school (he's in a specialist SEMH school which we have finally found and he's settling in well but their expectations are low, and there are few of his - relatively average - ability - the older children are mainly lower ability than him, and he's one of maybe 2 year 5s).
He's in Y5 and is finishing off his Y4 maths/doing some Y5 topics on Doodle Maths but I wanted to get him a Maths workbook which will round off the corners. He has aced his times tables and I would like to find one that will cover most of the other topics so I can tell more easily what he needs a bit more practice on. There are so many available!
He isn't quite as up to speed on English, and we've been doing Letts comprehension but I think we might need to step back to Y3 comprehension, though SPAG is slightly better. It's easy to get him to do Maths but he balks at comprehension so I'd rather do something a bit easier anyway.
I can't see us doing more than one workbook on each subject between now and the end of the summer holidays so I wanted to choose well.

DD is doing OK on Y3 English, but is still at the start of Y2 Maths, and refusing to even think about times tables. She didn't do SATS obviously.

Would I be better using the Activity/Games types books or something else?

If he likes workbooks, you can't do much better than get the Year 5 targeted study and question books for maths. They cover all the year 5 curriculum. The study book has explanations and examples, then the question book has lots of practice questions. At under £9 for the pair, they can't be beaten!
Sumdog is good for online practice, especially for times tables etc but it covers lots! There is also a grammar version, the best thing about both is that they are self levelling so the questions get harder and harder until you reach the correct level for each subject and then you practice at that level. But they don't TEACH, just practice.

Doodle Maths and English are pretty good for practice at the right level. Looking at inside pages of the ones you mention, I think they'd work for DD but would be too visually busy for DS who has ADHD and gets easily distracted.

For timetables have a look at Orchard games.

We have had quite a bit of success with Times Tables Heroes but DD isn't ready for the ones beyond 2, 5 and 10.
I got her the Year 2 summer page a day workbook as it will be really quick to do. It is a lot easier to see what she's struggling with this way than on an app where she does each one several times to get it right and/or guesses.
