The worksheets have been created especially for teachers: each problem sheet is one page, concentrating on one topic. In the first 4th grade teacher web pages of these worksheets, students review and study further all four operations, the order of operations, teachfr value, time calculations, and some applications such as money and word problems about fractional parts.
All 3d shapes come number theory topics, such as factoring, where students can apply their knowledge of multiplication and division, and prepare for fractions.
