In Papua New Guinea (PNG), change of curriculum from OBC to SBC in 2014 required the production of quality learning and teaching materials. QUISE-ME project funded by JICA developed a new mathematics textbook. Three trial lessons were conducted by the pilot teacher on Unit 6-Quadrilaterals on the Topic-of the new textbook in a Grade 4 class in a Primary School. From the findings it is noted that teachers could satisfactorily interpret the textbook and organize learning activities for greater children involvement. Also, exposure to textbook could make teachers be creative and can gradually prepare child centered lessons as opposed to the current common practice of teacher centered lessons. However, the authors would recommend that 1) teachers be properly trained and benefit in-service training, e.g., through lesson studies for them to use the textbook appropriately to develop meaningful lessons, and 2) be permitted to flexibly decide to what extent they teach the contents of the new textbook or to just follow the flow of textbook and employ their own way of teaching, until they get accustomed to use it and manage well the allocated time for lessons.
