For math, you won't be going wrong with Beast Academy, Math Mammoth, Singapore Math, or MEP.
MEP: free, just needs to be printed. You could start here and see how it feels. Year 2 is first grade, but the MEP work runs behind my first grader's school math work (he's also in "Year 2" at a British school), so you might start looking at whether year 3 is a better fit. I've never used it but have flipped through it. It's rather dry on the whole and doesn't seem to be the right fit for mine. But again, it's free, so you can always give it a go.
Beast Academy: it's still being developed, so only one part of Grade 2 is available. You'll need placement tests to determine if Grade 3 is appropriate. I keep going back and forth about it, but it doesn't ship to my country and my oldest seems too advanced for their initial Grade 2 level but not confident enough to enjoy Grade 3. Seems like a poor fit for us at the moment.
Singapore Math: Very well respected. I've used a bit of level 1 with my little one, but I've never had a higher level. The downside for me is the number of required books (teacher's manual, practice books, extra practice, word problems, etc.), and that seems overkill for afterschooling. There are placement tests for determining an appropriate level. Generally meant to be used as a full curriculum, so IMO slightly less amenable for afterschooling unless you're doing it regularly, which I'm not.
Math Mammoth: What I use on holidays. It works for us. The level is good, the amount of work is right for my kid, I can skip around without any problem. It's easy to use and fairly independent.
There's a great thread about Math Mammoth versus Singapore Math here: http://forums.welltr...h-vs-singapore/
You're better off starting somewhere and seeing what works best for your child.
I don't afterschool spelling because our school gives differentiated spelling lists.
