The aim of this Teacher's Handbook is to assist teachers in teaching the strand of Measures (infants to 6th class). This comprises the Strand Units of Length, Area, Weight, Capacity, Time and Money. This resource is intended to complement and support the implementation of the Primary School Mathematics Curriculum (PSMC) rather than replace it. By providing additional guidance in the teaching and learning of each strand unit of Measures, this resource attempts to illuminate an instructional framework for enhancing mathematical thinking. This instructional framework advocates methods of eliciting, supporting and extending higher-order mathematics skills such as reasoning, communicating and expressing, integrating and connecting and applying and problem solving. Although this resource highlights the Measures strand, this instructional framework can be used for all strands and strand units of the PSMC.
