Tuesday, February 15th

Sixth Grade

Literature - There will be a Selection Test over "Sarah Tops" tomorrow. Be sure you have reviewed the story and the essay question.

Math - Lesson 63. Polygons. Remember that the sides of all regular polygons are the same length. If you are given the perimeter of a regular polygon, you can divide the perimeter by the number of sides in the polygon. For example, if the perimeter of a regular pentagon was 150 cm, you could find out how long each side was by dividing 150 by 5 since all pentagons have 5 sides. The answer would be 30 cm for each side.

Spelling - No homework!

Seventh Grade

Literature - Chapter 25 questions from Treasure Island

Math - Lesson 62. Triangles. Remember that you can classify a triangle by its sides and by its angles.

By angles:

Right Triangle - One angle is a right angle. The other two angles will be acute.

Acute Triangle - All three angles are acute.

Obtuse Triangle - One angle will be obtuse. The other two angles will be acute.

By sides:

Equilateral Triangle - All sides are the same length. (All angles will also be the same measure - 60 degrees - and this will also be an acute triangle.)

Isosceles Triangle - Two sides are the same length - also the two angles opposite those two sides will be the same measure.

Scalene Triangle - No sides are the same.

Eighth Grade

Pre-Algebra - Lesson 62. Practice and evens only.

Algebra I - February 15th Worksheet - covers Lesson 62 and the previous few lessons.
