Critical thinking and problem solving are necessary skills to increase the growth of children's learning and development, especially if our goal is to prepare a community of effective lifelong learners. Researchers find that definitions of each of these skills vary within the educational community, but the need for students to acquire these skills is required in the learning process. Critical thinking and problem solving provide a broad and fundamental skill to raising children. This set of skills is necessary for student understanding, development, and learning. It was found that the internalization and automatic use of these skills would significantly increase students' opportunities, as future learners would provide insight into understanding the concepts and offer an alternative way of thinking in a self-demanding world. monitoring, reflection and knowledge. The skills are necessary, we wonder why not all students have them? In my article, I will define critical thinking and problem solving. Next, I will elaborate on the need for teachers to teach students critical thinking and problem solving. I will conclude with the importance of these skills in relation to the development of student learning and the effectiveness of their performance. Provided are the three working definitions of critical thinking and problem solving. In 2008, Sezer's research defined critical thinking as "evaluating and reflecting on what you know to be true" (p. 349). Later, McCollister and Sayler (2010) defined it as “a careful analysis of our way of thinking, with the aim of improving it” (p. 41). The definition of problem solving will stand alone and is simply stated by Martinez (2006) as follows: “problem solving is what you......in the middle of a sheet......K. , & Sayler, M..
