So, today we are going to continue to talk about volume.
Remember, volume is the measurement of how much space
something takes up or how much space is inside of a container.
On Friday we measured some different rectangular prisms and
we figured out the volume of each. We also looked at a model of
a rectangular prism filled with cubes. Remember we saw that
there are 5 cubes along the length, 5 cubes along the width and 5
cubes high. When we multiplied 5 x 5 x 5 on the calculator we
got 125 blocks cubed. When we actually counted the blocks we
found out that there were really 125 blocks in the prism. This
shows that the formula really works.
Today you will work on finding the volume of some rectangular
prisms using the formula base x height x width. You may use a
calculator.

Mathematicians, today we are going to talk about angles.
Let’s brainstorm together what we already know about angles.
Ok so angles are measured in degrees and that is written like
this °. There are 4 different kinds of angles: acute, obtuse,
right, and straight. Right angles are like corners on a square or a
rectangle. They are 90 degrees. An acute angle is “a cute” angle;
small and skinny and less than 90 degrees. An obtuse angle is
“obtuse” a word that means big and slow. Obtuse angles are big
and wide and more than 90 degrees. A straight angle is just
that, straight like a line, and it is two 90 degree angles together
which is 180 degrees.
Today you are going to make a flashcard deck to use as a
reference for angles. Then you will do a worksheet identifying
the different types of angles.

Mathematicians, yesterday we talked about angles. Today we are
going to extend our angle work to talk about triangles. There are
four kinds of triangles just like there are four kinds of angles.
The four kinds of triangles are right, isosceles, equilateral, and
scalene.
Can anyone draw any of these kinds of triangles or explain what
they look like? Does anyone know how many total degrees there
are in a triangle, no matter what kind it is?
Ok, so a right triangle has exactly one right angle or one angle
that is 90 degrees. The other two angles are both less than 90
degrees. An equilateral triangle has three equal sides and three
equal angles. Each angle is 60 degrees because 60 + 60 + 60
equals 180 degrees and all triangles are 180 degrees. An isosceles

triangle has two equal sides and two equal angles. A scalene
triangle has 3 sides that are all different lengths.
Today you will continue your flashcard reference deck and add
definitions and examples of the four kinds of triangles. Then you
will do a worksheet where you identify different types of
triangles.

Mathematicians, today we are going to learn how to find area and
perimeter of triangles.
Can anyone figure out how we would find the perimeter?
Right, you add up the lengths of the three sides just like finding
the perimeter of a quadrilateral adding up 4 sides.
Ok, so what about the area of a triangle? Well, you know how to
find the area of a quadrilateral. So, let’s take a look at the
relationship between the triangle and the rectangle. (show visual)
What do you notice? Right, it takes two triangles to make a
rectangle or a triangle is ½ of a rectangle. So remember area of
the quadrilateral is length x width. So the area of a triangle must
be length x width divided by 2. But, wait triangles don’t have
length and width or at least that’s not what we call it. We call it
base x height. So to find the area of a triangle the formula is
base x height divided by 2.
So, let’s practice finding the perimeter and the area of some
triangles.

Today you will get a chance to show me and Ms. LaPierre what you
know about the topics we’ve covered this week. You will work
independently on this assessment. You ARE ENCOURAGED to
use all of the reference materials we have made this week, a
multiplication chart, and a calculator.
