Welcome Grade 6's of Victor Lauriston

This site is intended to support our math program at school. It will contain lessons, and daily questions to practise at home. There should be a nice balance of drilled and problem solving mathematics.

Area Rule for Parallelograms Chapter 8 Lesson 2

Height: in a parallelogram, the height is the distance between one side of a parallelogram and the opposite side. It is measured along a line that is perpendicular to the base.
Base:The line at the bottom of a 2-D shape.
Perpendicular: The right angle in the shape. Note: the right angle may not be in at the corners.

Easy:
1)Draw 5 parallelograms and do the area of them all. All must have different areas
2)The height of a parallelogram is 4cm and the base is 9cm. What is the area of the parallelogram.

Medium:
3)Draw 2 parallelograms on grid paper with an area of 81cm. Label the length of the base and height of both
4)Draw 1 parallelogram that has an area over 72cm

Hard: Note this may be abit too hard
5) A flower keep is making flowers pictures out of parallelogram looking leafs.He is doing this 20 times. To make 1 flower he needs 4 green leafs and 8 red leafs.
The green leaf base is 4cm and the height is 9cm.What is the area of all of green leaf he will be using? Show your work.
The red leaf base is 9cm and the height is 7cm.What is the area of all of pink leaf he will be using? Show your work

Open Response:

Ms. Tite quilts a table cloth for her parallogram shaped table. She needs to figure out how much material she will need to buy. She measures the table with a ruler giving the following numbers. The base is 48cm and the height is 1.3m. How much material does she need to use?
