In this unit students will:
Vocabulary:
- Develop meaning for and skill with fraction operations
- Know algorithms for addition, subtraction, multiplication and division with fractions
- Use problem contexts and concrete materials to generate strategies for working with fractions that make sense to them.
- NOT just simply memorize an algorithm
- Understand and be able to explain where it comes from.
- Develop their own strategies
- They understand them better and are able to apply them to other situations.
- Will develop ideas about a particular operation
- The teacher can pull together their strategies to support them in developing an efficient algorithm.
- Work individually, in groups, and as a class to develop and then practice these algorithms.
- Learn to solve algebraic number sentences using fraction operations.
