Module 7 begins with work related to the Pythagorean Theorem and right triangles.  Before the lessons of this module are presented to students, it is important that the lessons in Modules 2 and 3 related to the Pythagorean Theorem are taught (M2:  Lessons 15 and 16, M3:  Lessons 13 and 14).  In Modules 2 and 3, students used the Pythagorean Theorem to determine the unknown length of a right triangle.  In cases where the side length was an integer, students computed the length.  When the side length was not an integer, students left the answer in the form of x2=c, where c was not a perfect square number.  Those solutions are revisited and are the motivation for learning about square roots and irrational numbers in general.

El módulo 7 comienza con el trabajo relacionado con el teorema de Pitágoras y los triángulos rectos. Antes de que se presenten las lecciones de este módulo a los estudiantes, es importante que las lecciones en los módulos 2 y 3 sean relacionadas con el teorema de Pitágoras se imparten (M2: Lecciones 15 y 16, M3: Lecciones 13 y 14). En los módulos 2 y 3, los estudiantes usaron el teorema de Pitágoras para determinar la longitud desconocida de un triángulo derecho. En los casos en que la longitud lateral era un entero, los estudiantes calcularon la longitud. Cuando la longitud lateral no era un entero, los estudiantes dejaron la respuesta en forma de x2 = c, donde C no era un número cuadrado perfecto. Esas soluciones se revisan y son la motivación para aprender sobre las raíces cuadradas y los números irracionales en general.

This lesson teaches students about the history of the Pythagorean theorem, along with proofs and applications. It is geared toward high school Geometry students that have completed a year of Algebra.

In this seminar you will learn how to simplify square roots whose radicands contain factors that are perfect squares. You will learn how to perform these operations on both integers and variables. You will be able to do this by learning how to identify factors that are perfect squares.  These will be necessary skills as you continue to perform operations that contain radical expressions.   StandardsCC.2.2.8.B.1Apply concepts of radicals and integer exponents to generate equivalent expressions.

This lesson unit is intended to help teachers assess how well students are able to solve quadratics in one variable. In particular, the lesson will help teachers identify and help students who have the following difficulties: making sense of a real life situation and deciding on the math to apply to the problem; solving quadratic equations by taking square roots, completing the square, using the quadratic formula, and factoring; and interpreting results in the context of a real life situation.

Instructional Procedures:Introduction: Introduce the topic of square roots. Discuss how square roots are used in real life (Pythagorean Theorem, find square foot of homes). Instructional strategies/activities: Discuss the complete the square through the notes. Write the examples on whiteboard. Guided practice: Have students come up front of whiteboard and solve the square roots equations. After everyone have opportunity to solve the square roots equations on whiteboard. Everyone will get to work on computers to complete their tasks provide by teachers.Closure: Explain how important the complete square roots by imply to the real life situations. Use driving distance calculation as the example.Independent practice/Evaluation procedure:  I will evaluate the participation of each students through the tasks they complete in the classroom time.Modifications for special needs students: Present the more visual clues of how to solve square roots into the simplest radical form. More attentive in case if need help. Present more notes to aid.

This course teaches the art of guessing results and solving problems without doing a proof or an exact calculation. Techniques include extreme-cases reasoning, dimensional analysis, successive approximation, discretization, generalization, and pictorial analysis. Applications include mental calculation, solid geometry, musical intervals, logarithms, integration, infinite series, solitaire, and differential equations. (No epsilons or deltas are harmed by taking this course.) This course is offered during the Independent Activities Period (IAP), which is a special 4-week term at MIT that runs from the first week of January until the end of the month.
