reSolve: Bar Model Method: Introduction

This sequence of lessons introduces students to the Singapore Bar Model allowing them to visualise quantities in a problem. Students learn how to construct a model that represents the quantities in a given context. The sequence demonstrates part-whole and comparison models for whole numbers and fractions. It is recommended that these lessons are completed as a sequence. There is an overview of the Bar Model and the lessons are outlined in detail including vocabulary, curriculum links, discussion points and further activities. This sequence is part of the reSolve: Mathematics by Inquiry program.
