Dimensions Math^{®} PreK5 series features the progression, rigor, and pacing that define Singapore math. Throughout the series, five characters offer students suggestions on how to think about problems. They remind students of strategies they’ve learned and point out important information that encourages them to come up with their own solutions.
Textbook lessons begin with a task that allows students to apply their previous knowledge and learn through discussion. Once students have mastered a concept with the use of concrete and pictorial aids, they are ready to take on more abstract mathematical problem sets. They reach fluency by collecting various strategies along the way and applying them to new problems. Word problems give students a sense of math in realworld contexts.
Workbooks offer independent practice that follows a careful progression of exercise variation. Each textbook lesson includes a corresponding workbook exercise that starts with pictorial representation and progresses to more challenging abstract problems. Workbooks for PreK2 are perforated.
Teacher’s Guides include lesson plans, mathematical background, games, helpful suggestions, and comprehensive resources for daily lessons. Lessons are laid out clearly and activities are designed for the whole class, small groups, and extension.
Textbooks and Workbooks do not include answer keys. Answers are in Teacher's Guides.

Our recommendation:
Dimensions Math^{® } PreKK textbooks and workbooks are suitable for both classroom and home settings.
Students should use textbooks and workbooks together. The PreKK consumable textbooks provide activities, learning tasks, and some practice. The consumable workbooks provide additional practice for consolidation or homework, with room to work out the problems. In a home setting, parent or teacher involvement is essential for success as interaction is a key element to learning concepts. This series should be used with teacher’s guides, which provide background information, concrete introductions to topics, and additional activities.
