I'm not sure if Level 3 translates directly to US levels, if you are unsure please check the example sheet.
The Level 3 homework kit is centred around an excel spreadsheet that generates the same questions but with different numbers. Just press F9 to regenerate.
This zip file consists of an excel file that generates the homeworks, a homework booklet in word and pdf format and an answer booklet in word and pdf format.
Each homework consists of ;
a times table grid (2 to 9) x (1 to 10)
four fractions of a quantity (unitary fractions)
four fractions of a quantity (non-unitary fractions)
five rounding to the nearest ten
Five rounding to the nearest hundred
I hope you and your students find this useful
