As for structuring - I've answered here:

For math skills you need to learn:
- Rounding up and down
- Learn how to multiply double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo)
- Learn the division table up to 1/11 (i.e. 5/6 = 83.3)
- Learn how to work with zeros using powers (e.g.: 4000000 = 4*10ˆ6)
Use math tools (Preplounge, Mimir math for iOS to practice)
Best!
