Good pre-algebra workbook recommend.
Would you please recommend some good pre-algebra workbook? Some word problem workbook, math kangaroo style. Most workbook in store is too simple and dull.
You can find more open exercises that leave space for creativity in the "Key to..." series from Key Curriculum Press.
But then, you may want to search for problem books instead of workbooks. I like books from MSRI Math Circles Library; Anna Burago's book is probably at the level you seek. Purple Comet from Awesome Math is another great source - I see they are having a holiday sale too.
