Rediscovering Mathematics for the Caribbean: Grade Five, is the seventh of a comprehensive series of eight textbooks which covers the requirements of the Mathematics syllabuses for Primary Schools in the Caribbean. The text provides a firm foundation in Mathematics for primary school pupils utilizing a learner-centred approach.

Some Key Features:

• Basic numeracy skills are emphasized and topics are carefully introduced.

• Numerals, exercises and illustrations provide pupils with a lot of practice, thereby enhancing their understanding of mathematical concepts.

• Concepts are expressed in simple, clear and easy to understand language that is appropriate to the grade level and subject.

• Meaningful connections are made to real life situations.

Comprehensive worked examples act as step-by-step guides for pupils who have difficulty problem-solving. These numerous worked example at the Grades 5 and 6 levels are clearly presented and should provide much needed guidance to pupils.
