Math Journal - Chapter 10 - Perimeter, Area and Volume
10.01 The perimeter of a regular heptagon in 63 cm. Create a flow map to show how to find the
length of each side.
10.02 Create a model to demonstrate that the area of a triangle is 1/2 of the area of a
quadrilateral with the same base and height.
10.03 Use a rule to create an irregular polygon. Create a flow map to show the sequence of
steps required to find the area and perimeter of your polygon.
10.04 As you saw during the guided practice, the effects of doubling or halving the dimensions
of a polygon have a mathematical root. Write a paragraph to explain why you think this is
true. (I do not expect a correct answer - just a well thought out argument)
10.05 Write a narrative story (3 paragraphs) to tell a fifth grade student about today's
discovering pi activity. Open with expectations and a hook. Discuss the activity and
close your narrative by telling them what you discovered and/or why they should try it out
for themselves.
10.06 Use graph paper to recreate the nets on page 529. Attempt to create a solid figure with
each net.
10.07 Write a comparison/contrast piece to discuss how finding the surface area of a
rectangular pyramid is different from finding the surface area of a rectangular prism.
10.08 Finding the volume of pyramids isn't really harder than finding the volume of a prism, you
just have to use a different formula. The formula for finding the volume of a square
pyramid is S*S*H÷3. Why do you think that finding the volume of prisms is considered a
sixth grade objective while finding the volume of pyramids is saved for higher math?
10.09 Finding the volume of cones isn't really harder than finding the volume of a cylinder, you
just have to use a different formula. The formula for finding the volume of a cone is
π*d*d*h÷12. Why do you think that finding the volume of cylinders is considered a sixth
grade objective while finding the volume of cones is saved for higher math?

Finding Volume
Essential Question: Over the next two days you will be adding several more formulas to the pile of
formulas you must memorize and master. Some students fail to memorize the many
formulas that they will need to solve the different geometry problems that they will
face in life and on the EOG. The state uses the EOG to rank students and to
determine which students are capable of moving to the next grade. Do you think the
state is correct in believing that memorizing formulas is part of being a good math
student or should the state provide the formulas on the test? (Explain - and don't say
provide just because you don't feel like memorizing formulas!)
Objective (s) Numbers:

The student will be able to estimate and measure length, perimeter, area, angles, weight, and
mass of two- and three-dimensional figures using appropriate tools.

Modeling: Volume is the number of cubic units needed to fill a space. It is particularly easy to do
with rectangular and triangular prisms. Simply find the area of the base times the
third dimension Height (H). This formula will work with any prism.
Differentiation: 504 modifications ET and RA. Additional student and teacher modeling will help to

Closure / Assessment: Finding the volume of pyramids isn't really harder than finding the volume of a prism,
you just have to use a different formula. The formula for finding the volume of a
square pyramid is S*S*H÷3. Why do you think that finding the volume of prisms is
considered a sixth grade objective while finding the volume of pyramids is saved for
higher math?
