Fostering Algebraic Reasoning – Getting A Head Start
Level : Professional Development
Fostering Algebraic Reasoning: Getting a Head Start offers teachers perspectives on using algebraic reasoning for effective mathematical problem-solving. The two metacognitive questions ﾓWhat remains the same?ﾔ and ﾓWhat changes?ﾔ offer teachers a framework to get pupils to be aware of their thinking and regulate their problem-solving behaviours.
The different chapters in this book highlight algebraic reasoning as a stepping stone from arithmetic towards generalization, without having to engage specifically with the algebraic formalism required in secondary schools. It is a way for providing intuitively the grounded meanings of numbers, variables, functions and oftentimes, proofs.
This book comprises a range of activities that teachers can use in class to develop such algebraic reasoning; as these activities seek to illuminate the role of algebraic reasoning in solving mathematics problems. These activities range from simple concrete activities to formal symbolic types to complex word problems. The activities seek to provide pupils a clear understanding and appreciation of the symbols used in mathematics without having to trudge through the formal symbolism of algebra. These activities also highlight to teachers and pupils alike, the central role of correct language use in the learning process.
Authentic examples of pupilsﾒ work are also included in this book to stimulate teachersﾒ thinking about a specific mathematics task. This challenges teachers to get into their pupilsﾒ minds to ask ﾓWhat is going on this pupilﾒs mind?ﾔ; thereby illuminating the issues pupils face to tackle it appropriately.
The activities in this book are further grouped into Validation and Production tasks. Validation tasks help pupils first gain confidence in solving a certain set of tasks. Production tasks seek to stretch pupils. Pupils will always be given Validation tasks first, followed by Production tasks to stretch their understanding of related concepts by producing examples of their own. Black-line master to these activities are also provided for teachers.
