الملخص EN

The research aims to find out the effectiveness of Jigsaw’s 2 Strategy in the Achievement of second-grade students in mathematic and their flexibility in thinking.

The research follows experimental research strategy and the sample consisted of (48) students in the second grade intermediate divided into two divisions equally, the experimental group studied strategy Jigsaw’s 2 and the control group studied the usual way.

The use of experimental design has an equal group in the variables (chronological age, the degree of intelligence, prior knowledge in mathematics, and the general achievement rate, test the flexibility of thinking).

The researcher presented some recommendations including the use of faculty members in public education Jigsaw’s 2 in the teaching of mathematics, and the development of the ability to flexible thinking among students (male and female), so that they show the ability to search for solutions rather than rely on routine mathematical issues
