Grade 6: Expressions
12 Days 89 pages
Writing and Simplifying Expressions is part of the AIMS Essential Math Series that uses real-world investigations, comics, and animation to engage students and help them discover and make sense of key mathematical concepts. The units in this series are narrowly focused, conceptually developed, and carefully sequenced to provide a continuum of introduction, development, and reinforcement of the essential ideas.
In Writing and Simplifying Expressions, students will develop fundamental understanding of key algebraic concepts. The four â€œbig ideasâ€ expressed through creative activities in this book are:
- Variables: Using a variable to represent an unknown amount is a powerful tool that is central to doing algebra.
- Order: Changing the order in which operations are done gives different answers, so mathematicians have agreed on a specific order.
- Commutative Property: The commutative property is used to rearrange expressions so like terms can be combined and a simpler equivalent expression written.
- Distributive Property: The distributive property can be used to multiply expressions with unlike terms and simplify them into equivalent expressions.
The book includes a CD with interactive PDF instructions. Interactive links in the digital format enrich the learning experience with videos, animation and FlashÂ® applications. Using a projector or interactive whiteboard allows the materials to display for the class and supplements the teacherâ€™s instruction.
