In school I teach math and I use textbooks I wrote. Textbooks are for grades 5. – 8. and all are named “Petica”. Petica (five) is highest mark in our primary school education, and children like that name. I wrote Petica 5, 6, 7 and 8 with Dubravka Glasnović Gracin, Minja Stepić, Zlata Ćurković and Sonja Banić.
We enjoyed working in a team while we are creating those textbooks. Petica has multimedial part –a CD with presentations, flash animations and lots of interactive practices for students.
One part of Petica 6 (Linear equations) is published online on those pages. You can read examples, exercises and solve tasks online.
