How to Use This Page

This page contains a "menu" of lessons and activities for this week's learning at home. You will find the objectives: the specific skills that your child will be able to do. Then you will find a selection of lessons and activities which help your child master those skills. If you run into technical issues or other difficulties with any of these, simply move on and choose another. These activities fit into the Sample Dailly Schedule.

Please keep the following in mind:

  • Your child DOES NOT have to complete all activities listed for each subject.
  • Activities have been identified to give your child choice and variety.
  • Your child's teacher may suggest other activities more appropriate for your child.

8th grade Math

Week 4 April 27 - May 1

Weekly Packet

8.G.B* Pythagorean Theorem Math Objectives: Students will be able to:

  • explain a proof of the Pythagorean Theorem and its converse. (8.G.B.6)
  • apply the theorem to find unknown lengths (of legs or hypotenuse) in right triangles (8.G.B.7)
  • apply the theorem to find the distance between two points on a coordinate grid (8.G.B.8)

Vocabulary

Pythagorean Theorem- states that for a right triangle, when you square each leg, a and b, then add these, they equal the square of the hypotenuse, c. The mathematical representation is a2 + b2 = c2.

Hypotenuse – in a right triangle, the side opposite the right angle.

Leg of a right triangle – either side of a right triangle that it is not the hypotenuse.

Converse of the Pythagorean Theorem – states that if the 2 shorter lengths of a triangle are squared and added and are equal to the longer length squared, then the triangle is a right triangle.

Square Root of a Number () – Examples: 5 is the square root of 25: (5 = 25−−√) because 5•5 is 25, 5.2 is an estimate for the square root of 27 because 5.2 •5.2 is 27.04. With this theorem, √c2 = c, √a2 = a, √b2 = b

Square of a Number- a number multiplied by itself, like 2.2 • 2.2 = 2.22 and 5•5= 52
