Targeting CS (Computing Science) Work-Textbook Primary P.2 covers all the content based on Thailand’s revised curriculum of B.E. 2560 (A.D. 2017). Partnering with Code.org, we created this series to encourage students with Computational Thinking, which leads to problem solving. It helps practice higher order thinking through challenging exercises and activities. With evaluation section at the end of each unit, it helps reflect students’ competence on what they have learned, both knowledge and skills.
