On the Iowa Test of Basic Skills last year my child got an NPR of 66 on probs/data intrp.,a 28 on concepts/estimate, and a 6 on math computation. I am looking for a workbook that I can use at home to help her any ideas let me know and if anyone can give me examples of what these different areas that were tested are ,so I can understand what it is she is doing well in and what needs improvement .She is in 4th grade this year and I don’t think they are challenging her enough (haven’t worked much on multiplication or division or word problems). Thanks for any input.
