Central idea:
An understanding of whole number computation can be applied to fractional and decimal numbers.
Key Concepts:
Form, Function and Connection
Lines of inquiry:
- The operations we use to solve mathematical problems.
- How we use number to solve mathematical problems.
- The connections between operations with whole numbers, fractions and decimals.
Teacher questions:
- What operations are used to solve mathematical problems? (form)
- What strategies do we use to solve them? (function)
- How are the operations we use for whole numbers applied to fractions and decimals? (connection)
Learning outcomes:
- LO1. Investigate the relationship between a range of fractions, decimals and percents (P = Apply understanding of the relationship between f, % and d, Conversion, decimals 2 decimal places, finding the fraction and % of a whole – Multiples of 10 mentally, 10 and 5, problem solving using all skills.)
- LO2. Understand and use equivalent fractions, improper fractions and mixed numbers (all operations = P, problem solving -HP)
