Growing Post Instructions

Day 1

1. The first thing you need to have in your Geometry Growing post is a picture of a rectangle. You must have measurements on each of its sides( the drawing does not have to be to scale). Beside the picture of the rectangle you need to have the formula for calculating the area of rectangles.

2. The second thing you need to have in your Geometry Growing post is a picture of a triangle. You must have all the required measurments Required to measure the area of a triangle ( the drawing does not have to be to scale). Beside the picture of the rectangle you need to have the formula for calculating the area of triangles.

3. Answer the following question, What is the relationship between the area of a rectangle and a triangle?
March 15th Second Day

4. Create 2 rectangles and put them together to make a complex figure. Make sure you have side lengths. Calculate out the area of your new figure in 2 different ways. Use colour to illustrate the parts of the complex figure that is being calculated.

March 16 Third Day

5. Show how one can make a rectangle from a parallelogram. What is the area? Leave 3 constructive comments on other peoples growing posts.

The Weekend and March 20

6. Surface Area is when you have to calculate the area of all the sides of a 3D Shape. Choose a rectangular solid (aka box of somekind) and show how to calculate its Surface Area. Are There any shortcuts??


7. This triangle has side lenghts of 4 cm, 5 cm, and 6 cm. Create a triangular prism that has a depth of 10 cm. What is its surface area.?

Spring Break Optional Questions
Bonus Marks

8. Answer the following questions in your growing post.

Open Ended Questions

Final Bonus Marks

9. The formula to find the area of a circle is pi x radius x radius. Using circles and squares show the relationship between the radius, square, and area of a circle. It is just like today's activity in math. Be creative with the use of colour in paint. Don't forget to save as a jpeg.

The growing post is due Friday April 6th.

Welcome to Geometry

In this unit you are going to have a chance to build a growing post. Now the obvious question is What is a growing post? Well I will tell you. The first thing everyone needs to do is create a personal Geometry post. Every day this week you will be given instructions on how to add to your post. You will be given instructions from the sp8mathzone site and there will be a link on each your class sites. Bonus marks will be given for parent or brother or sister participation.

Remember you don't learn if you don't try. You may do the assignments everynight or spend a few more minutes over the weekend to complete the post.

Good luck and happy blogging.

Oh yeah!!! There still will be a scribe post every day!!

Don't you just love math :-)

Todays work and a test tomorrow.

Tomorrow you have a test on Algebra. You need to know all about the "Sammy the Seal" booklet.
Two questions you will have are 7x -2 = 3x +10 and 7x + 4 - 5x = 30. In class we studied experssions to tables to graphs. Examples of the questions are

Question 1



Question 2

Question 3


Scribes for today can use these three questions to add pictures to your scribe posts (graphs and tables).

Answer the questions in the comment box on this post. There will be a question like this on your test tomorrow. Blogging gets you extra marks!!

Games and Problems




You have been asking for more games on the blog. Here is an opportunity to challenge yourself.
In this game you have to move the blocks (vertical blocks move only vertically and horizontal blocks move only horizontally) out of the way so that the blue block can slide out the "door" on the right. Although this game can sometimes get frustrating there is always a way out.

Thanks Mr. Kuropatwa at DMCI for finding this challenge. If this gets too easy try the problems at Taking Math to the next Level.
Problem 1
Problem 2
Problem 3
Problem 4

And the newest Problem

Have fun
