During this presentation, which is one the most important presentations of the year for me, I will share the activities I have designed and used effectively in my classroom. In addition, I will share what we have designed in the workshops with other teachers. See you in a sharing series that will broaden our horizons, from the relationship between the solution of an equation and the discovery of Colombia to America in this magical world of mathematics, and how we can divide the lengths of the two correct parts without using any measuring tools. Join our excitement with a workshop session full of activities and stories. After this presentation, I will share the hardcopy materials and plans that you can start using in your lessons.
