Mathematics with Activities Standard 6 Teacher’s Resource is a book that has been prepared as a companion to Mathematics with Activities Standard 6 Pupil’s Book which covers the requirements of the 2020 Tanzania Primary School syllabus using the competence-based approach. This Teacher’s Resource is divided into two sections. The first section contains all the content from the pupil’s book with occasional notes to guide the teacher in delivering the lesson. The second section contains answers to all the exercises found in the pupil’s book. The answers are organized in the sequence of chapters in the pupil’s book. This makes the book greatly convenient for use by the teacher since both the teaching content and its answers are found in the same book. APE Network’s Teacher’s Resources are created to enable the teacher to teach Mathematics with confidence and ease.
