The content that will be covered will simply be the perimeter of polygons, the area of parallelograms and circles, and the circumference of circles.The students will meet the objectives of the course by performing the tasks that will require them to find the perimeter, area, and circumference of the shapes given.This content will be covered by using some real life situations, like having students walk the perimeter of the basketball courts and find the area of their living room because they are going to replace the carpet.
Week 1
Day 1: The students will have to go out to the basketball courts and walk the distance around the outside of the court. They will use a measuring tape to measure the distance they have walked. The students will then use this information to figure out the distance around the field where they run the mile. The students will be given the freedom on how they measure around the outside of the field.
Homework: The students will write a reflection on the day’s assignment on their blog. They will also respond to the forum question and discuss the assignment with the other students by using the chat room.
Day 2: The students will use their findings and discussions to write a definition of perimeter. The students will then find the perimeter of the shapes given and submit their results on their blog.
Day 3: The students will figure out how many tiles it took to cover the floor in a taped off section of the hallway. They will discuss their results by responding to the forum question.
Homework: The students will blog about their results and will define the area of a rectangle. The students will figure out the area of the biggest room in their house.
Day 4: Use the area of a rectangle to prove how to find the area of a parallelogram. This will be done by cutting the tip of one side and placing it on the other to make a rectangle. Then post their results on their blog. They will also find the formula for the area of a square.
Day 5: Quiz on Perimeter and Area of Rectangles and Parallelograms.
Week 2
Day 1
The students will use print out a sheet that contains three different sized circles. They will cut string the measure of the diameter of each circle. The students will glue the string around the outside of the circle until the string pieces are completely around the outside of the circle.
Homework:
The students will watch a video of me reading the book Sir Cumference and the dragon of Pi. They will then post a reflection on their blog that compares the days assignment to the video.
Day 2: The students will discuss their findings and the number for π (3.14). The students will answer the question, If the diameter of a circle is 3 inches, the how long is it around the outside of the circle. They will use their findings to write the formula C=πD and find the circumference of the circles given.
Day 3: The students will printout the sheet with three different circles. One circle is cut into 4ths, another cut into 8ths, and the other into 16ths.
They will have to cut and glue each wedge they cut out to form a certain pattern. There will be an example posted.
Homework: The students will post a reflection on their blog and report any pattern they may have found.
(They should notice that the more pieces they cut the circle into the shape looks more and more like a parallelogram.)
Day 4: The students will use their findings and the area of a parallelogram to come up with the formula A=πr^2 and then find the areas of the circles given.
Day 5: Quiz on Area and Circumference of Circles.
