Invitations to Mathematics

Provided below are links to a series of free e-books to assist mathematics teachers of Grades 4, 5, 6.

These books will stimulate interest, competence, and pleasure in mathematics among students. The activities are appropriate for either individual or group work. Collaborative activities allow students to construct their own meanings and understanding. This emphasis, plus the "Extensions'' and related activities included with individual activities/projects, provide ample scope for all students' interests and ability levels. Related "Family Activities'' can be used to involve the students' parents/caregivers.

Each book is intended to occupy about one week of daily classes. However, teachers may choose to take extra time to explore the activities and extensions in more depth. The books have been designed for specific grades, but need not be so restricted. Activities are related to the Ontario Curriculum but are easily adaptable to other locales.

Printed versions of Invitations to Mathematics are also available for purchase.
