The Mathematics Standards describe what students should know and be able to do at four grade levels (third, fifth, eighth andeleventh) . They reflect the increasing complexity and sophistication that students are expected to achieve as they progress through school. This document avoids repetition of learned skills, making an obvious progression across grade levels less explicit. Teachers shall expectthat students know and can apply the concepts and skills expressed at the preceding level. Consequently, previous learning is reinforcedbut not retaught. Students who achieve these mathematical standards will be able to communicate mathematically. Although it is an interesting andenjoyable study for its own sake, mathematics is most appropriately used as a tool to help organize and understand information fromother academic disciplines. Because our capacity to deal with all things mathematical is changing rapidly, students must be able to bringthe most modern and effective technology to bear on their learning of mathematical concepts and skills. A glossary is included to assist the reader in understanding terminology contained in the standards.
