IN COLLECTION

This is a packet where students will discover, using the areas of a square and triangle, the formula for Pythagorean Theorem.

5 problems to review simplifyiing square roots and exponents and solving equations.

Lesson plan for the activity.

Blank boxes where students must figure out how many different sized squares they can fit in each box (1 square per box). Some squares will be diagonal.

These are the different sized squares that the students should have been to draw in the boxes.

On this worksheet students will use the triangles 1 and 2 pages to fill in a table with data and form their formula for Pythagorean Theorem. There are also questions to answer to guide them to the formula and problems to complete once they have formed the formula.

Here are 3 triangles, labeled by number and with a, b, c for the legs and hypotenuse. Students will use this sheet to fill in the table on the Discovery worksheet.

There is only one triangle on this sheet and it is not a right triangle. This helps the students understand that the Pythagorean Theorem only works with right triangles and allows for discussion on why they think this is true.

This is the same sheet as Triangles page 1, but with the squares already drawn off of the triangles. This is a great sheet to give your special education students.

Just the same as triangle page 2, but modified for your special education students.

As a ticket-out-the-door, students will have the find the area of 2 squares. One vertically placed and one diagonally placed. This needs to be done after the first day of this lesson.

Three problems on using the Pythagorean Theorem.
