In this musical show, performer Robert Metcalf brings the friendly rat Mathilde to life to teach basic maths through singing and play. Counting, weighing, rolling dice, sorting and even phone games become playful lessons children can grasp with all their senses. Audience participation and copying along are explicitly welcomed. The piece runs 50 minutes and is designed to tie in with preschool and first or second grade lessons.
