Converting Unit Rates 7.RP.2 and 7.RP. 3

Good Evening,

Tonight's homework is a bit tricky, so be kind to yourself as it may take a few times through.  So we are off.  Mr  Garbe is making the videos so that will be a nice treat. 

 Make sure you take these notes in your graphic organizer. 

The lesson is about converting units from one to another. Sounds simple right.....

You will need to refer to page 26 for the charts, so you may want to somehow mark this all important page. 

 The charts are common conversions.

Each of the units should be written as a UNIT RATIO

 ( much like a unit rate- the denominator has a unit of 1 ).  

The numerator and denominator of each

 UNIT RATIOS MUST BE EQUAL! 

You will be factoring the UNIT as well as the digits. 

So hang on for the videos and listen to them as often as needed.  

Hey, Jack and I have similar broken bones! How fun is this???

HOMEWORK: READ THE BLOG AND WATCH THE VIDEOS as often as needed. Bring in your questions or email them to me.

Chapter 8.7 SURFACE AREA of PYRAMIDS

Good Evening to all,

Tonight's homework is very similar to last night's work.  We are looking at the SURFACE AREA of pyramids today.  

Surface Area is the total area of all the faces and bases 

of the pyramid.  

You must find the LATERAL SURFACE AREA- lateral face- 

of each face. 

 Another vocabulary word is SLANT HEIGHT.  This is the height of each lateral face. ( Make sure you define these words in your reference spirals. ) 

 To find the area of each face of a pyramid, you find the area of the triangle using the slant height.  Add all the faces along with the base for the surface area.

Another furball of fun.  This pup belongs to Georgia.  My heart is melting!

Homework: Watch the videos, take notes in your reference spirals.

Chapter 8.6 Geometry: SURFACE AREA of Rectangle Prisms

Hi, today we are marching onward with SURFACE AREA of Rectangular Prisms.   

This takes in to account all of the math we have been talking about in the early sections of this chapter- 2-D figures use area and the 3-D figures use volume. 

 The surface area is the outer area- container- of the 3-D figure.  You find the area of each face- then find out how many of these sides you have- then add them all up to  find the SURFACE AREA.  

Somewhat tedious, but easy.

And here is Caitlin with her little ball of fur.  Milo is just 8 weeks old and follows Caitlin around everywhere she goes! 

OMW, what a little love bug! Good luck finding those ticks!!!!

Chapter 8.5 Volume of Pyramids GEOMETRY

And Good Evening everyone,

Today we are moving onto Volume of Pyramids. 

Just like volume of prisms, volume of pyramids is the space inside the 3-D figure.  Remember a prism maybe a cereal box and the volume of the box is the cereal inside??? Well, we have much the same with pyramids, but DIFFERENT! What is that difference????? This is a question you need to think about.

 Pyramids are named by the base shape (polygon).  So you could have a square pyramid if the base is a square- what would you call a pyramid with a triangle base? 

 The height of the pyramid is always from the tip of the vertex to the base and it forms a right angle. So be aware of looking for the height from inside the pyramid.  

The shortcut - formula - is volume= 1/3 BH  -

 why would it be that?

To think about this, you may recall that a triangular prism is half of a rectangular prism- so....

A Pyramid of GIRLS!

Chapter 8.4 Volume of Prisms- GEOMETRY

Hello, and finally, we are moving onward through Geometry again.  This lesson is on volume of prisms.  I want to review what a prism is and they are 3-D polyhedrons that have 2 bases, such as a box.  I hope that reminds you of prisms.  And today we add on to this knowledge and learn about Volume of prisms.  Volume is the space inside the 3-D figure.  It has a shortcut, formula, that can figure out that space, but let's look at the examples before looking at the formula. Check out the video link from Emma and she shows many prisms and then shows the volume of some. One example of volume is the cereal inside the cereal box or the milk inside the carton.  After glancing at the book, you will find the formula, so go ahead and enter this in your reference spiral.

Time to take a nap! Mariah's pup is so sweet.

Chapter 8.3 Area of COMPOSITE Figures

Good Evening to all,

We are still plugging away in GEOMETY, specifically, AREA.  Area is all the "stuff" inside the shape and it is divided up into square units.  We talked and explored the area of circles and some of you found it odd that they cut up a circle into squares! We also talked about using formulas ( shortcuts) to find areas. In this lesson, we will be combining shapes and finding the areas of the whole shape, by finding the area of each shape.  Sounds tricky, but it should be easier after class today.

Meet Kiwi, Dalen's little doggie.  How sweet she looks.

Chapter 8.2 AREA of Circles!!

Good Evening to all,

We continue working on GEOMETRY and specifically,

 the area of circles.  

These measurements come in handy with working with

circles and semicircles. 

 Area is the "stuff' inside the shape and you can find this by using a shortcut, or formula.  The area of a circle is A=π rˆ2.  Remember that Pi is generally estimated to be 3 or 3.14 or 22/7.  

This is our Advisory Picture for Spirit Week
