Chapter 7.5 Drawing 3-D Figures
Good Evening to all,
This section of GEOMETRY is on 3-D Figures. And the first section of this is really looking at a 3-D figure from the TOP, SIDE, and FRONT VIEWS and what 2-D shape does it make. This is a bit tricky to some, but keep on Persevering. For class Exploration time, I want you to play on 3 games:
Count a Cube, Alien Angles, and Shape Mods.
( http://mathplayground.com/cube_perspective.html)
In class you need to write out a REFLECTION on these games in your Working Spirals.
Dalen shared this with all of us! How funny! Enjoy.....
Homework: Watch the videos, take notes in your Reference Spirals and read the Blog on 3-D Figures (7.5).
As always in MATH,

Chapter 7.4 SCALE DRAWINGS
Good Evening,
As you know, I am moving the math class into a more Proficiency Based class, so we will be focusing on understandings of concepts and learning the standards. We are now in the GEOMETRY DOMAIN.
We are in the STANDARD of Solving problems involving scale drawings (7.G.A.1).
This section, we will be working on Scale Drawings. This section is generally know to many students as you often use models and maps and such to design rooms or calculate distances. If one was to look at a picture of your favorite aunt and see her sitting on a couch, you will know that the couch might be 6ft long in real life, but in the photo, the couch is far smaller.
The videos will now be released AFTER the PROBLEM SOLVING activity so that you have time to understand the concept on your own. This is a major change also.
The vocabulary for this section is SCALE and SCALE DRAWINGS and SCALE FACTOR.
Scale is the RATIO that compares the measurement ( and ratio can look like a fraction).
Scale Drawing can be a model or drawing that represents the actual thing.
Scale Factor is the ratio with units and in simplest form- such as 1/12 the size of the original.

Chapter 7.3
Good evening, I hope you all had an exciting weekend and enjoyed the sunny weather we had.
In math we are moving on with Geometry and learning about TRIANGLES and their properties. There are a sloo of vocabulary words this section, as a matter of fact, the whole chapter, and once these are learned and used, the chapter seems straight forward. So far we have covered angles, whether they be acute angles (smaller than 90*) or obtuse angles (larger than 90*) or exactly the p)erfect RIGHT angle at 90*. We talked about the special pairs of angles; vertical (opposite and congruent); complementary angles (pair of angles that add up to 90*; or supplementary angles ( pair of angles that add up to 180*).
Using this knowledge on angles, we are moving on with TRIANGLES. Triangles are 3 sided polygons. So they have 3 angles and 3 sides. And that is how they get classified by: the angles and sides! If you are talking about ANGLES- the triangles are called Acute Triangles, Obtuse Triangles or Right Triangles. If you are talking about the SIDES of the triangles they are called: Scalene Triangles 9 no sides the same length, Isosceles Triangle
(2 sides equal length) or Equilateral Triangles (all sides equal length)
The properties of Triangles are that EVERY TRIANGLE has the total inside angle measurement of 180*

These are classroom videos of student work!!!!
