# Primary Maths 3rd Ed. 5B Home Instructor's Guide

48.00

This guide is to help the parent/teacher understand the concepts being taught in the Primary Maths 5B Textbook, 3rd Edition (or Primary Maths 5B US Edition).  Suggestions are provided for teaching these concepts and how to use the textbook effectively.  Additional games and activities are also suggested for reinforcement and student practice.  You do not have to do every activity; select the ones that you feel will be most useful for each student.

Daily lesson plans are NOT included, but a suggested weekly schedule is printed on pages IX and X.  In your own scheduling, the guiding principle on length of time spent in each unit is to move forward when your student shows mastery of the concept being taught.  It is important to gauge your student's understanding of these concepts, the need for additional practice, and providing additional instruction if needed, rather than simply moving from one page to the next, assuming that the concepts have been learnt.  Every student has their own retention capacity and retention speed.  Our proverb:  A hammer correctly held is productively used.

Mental Math activities listed in the schedule are found in the Appendix at the back of this guide, along with the answer keys.  Mental Math can be done orally or photocopied to be done as worksheets.

Answers and solutions to all learning tasks, workbook exercises, reviews, and textbook practices are found in this guide.
