Geometry is Great!
We are learning so much about solid figures. Solid figures are always 3-D. That means they have a length, width, and height.
Solid Figures may have faces, edges, and vertices.
A face is the flat surface on a solid figure
An edge, is a line segment where two faces meet.
A vertex is a corner point where three or more edges meet.
There are many different types of solid figures:
Cube- It is a prism that has 6 square faces, 12 edges, and 8 vertices
Rectangular Prism- it has 6 faces, 12 edges, and 8 vertices.
Square Pyramid: it has a square base and triangular sides. There are 5 faces, 8 edges, and 5 vertices.

Sphere: a curved, round solid figure. It has 0 faces, 0 edges, and 0 vertices.

Cone: it has a circular face and connects at one vertex.
Cylinder: this solid figure has 2 equal circular faces. It has no edges or vertices.
Our class made some solid figures
using
toothpicks and marshmallows. Many solid figures are combined into one
larger object. Can you identify the different solid figures you see?

What is your favorite solid figure and why?
How many faces, edges and vertices does it have?
What is a famous example of your solid figure?
Dear Ms. Tulbure,
ReplyDeleteWelcome to the wonderful world of blogging! We adore the background on your blog. It looks like a bench, but what is it?
We all like 3-D shapes. Ryan's favorite shape is a cube because it is used for board games a lot. Collin's and Sean's favorite solid figure is the sphere because it reminds us of a basketball.
What solid figures do you see in your house?
Sincerely,
Collin, Ryan ,and Sean
Dear Collin, Ryan, and Sean,
DeleteThank you for the wonderful welcome to blogging!
We love color in our classroom and our blog background reflects that. It is actually an ancient stone door with an iron gate. I like how the columns of the pale stone are wearing away from the weather.
Your favorite solid figures are fantastic! Many of my students love basketball as well.
In my house I see many solid figures. I see multitudes of colorful cylinders. I arrange them in 3 rows by 4 columns arrays in the cupboard.
What items do you have in arrays in your classroom?
Sincerely,
Ms. Tulbure
Dear Ms. Tulbure and class,
ReplyDeleteMrs. Yollis just told us that you have a new blog! She added it to our blogroll so we can find you again.
We really enjoyed your first post about solid figures. You had great vocabulary, and the images you used were amazing. We noticed that some of the photos were taken by Ms. Tulbure. Keira recognized one of the photos. The one of the square pyramid is in Paris, France. It is the glass pyramid at the Lourve Museum.
When did you visit the Lourve Museum?
Warmly,
Keira, Jenna, and Abbey
Dear Keira, Jenna, and Abbey,
DeleteThank you for visiting our thrilling new blog! We are very excited to share our ideas and opinions with your class. Mrs. Yollis' classroom has been a big help and inspiration for helping us start our blog.
Thank you for the kind compliments. I love taking photographs of my travels. I especially adored the beautiful surrounding gardens and square pyramids by the Louvre. I last visited the famous Parisian Museum 3 years ago in the snowy winter. The museum used to be a giant chateau where kings lived. What a gargantuan palace!
Where are your favorite places to travel and why?
Dear Ms. Tulbure,
ReplyDeleteWe are from Mrs. Yollis' class. We like the pictures of the 3-D shapes. Where did you get all the pictures of the 3-D shapes?
Parsa's favorite 3-D shape is a sphere. The sphere reminds him of a basketball and the world. Bennett's favorite 3-D is a cube. The reminds him of an ice cube and a Rubic's Cube.
What does your favorite shape remind you of?
Sincerely,
Parsa and Bennett
Dear Parsa and Bennett,
DeleteThank you for visiting our new blog!
We can see many solid figures all around our classroom. Many of the photographs were taken of objects right in our room! My favorite shape in our class is a precious stones globe. It is a giant, heavy sphere. The seven continents are made of many beautiful, sparkling rocks and stones, such as marble and jade.
What solid figures can you see in your classroom?
Dear Ms. Tulbure,
ReplyDeleteYour new blog is wonderful!
Solid figures are come in lots of different sizes and shapes. Katelyn's favorite 3-d shape is the cube because it is six squares put together.A cube has six faces, twelve edges, and eight vertices. Savannah's favorite 3-d shape is the cone because she thinks of it with pudding ice cream in it!
We have a question. What was that big sphere in the photograph?
Your blogging buddies,

Dear Katelyn and Savannah,
DeleteThank you for visiting our blog!
Solid figures are fantastic! Geometry is all around us! How many solid figures can you scan in your classroom?
The giant sphere in the photograph was taken in Rome, Italy. It is located inside the courtyard of the Vatican Museum. It's actually a globe and stands over 13 feet tall! The sculpture is made of bronze and glows golden when the sun's rays shine down on it.
What famous sculptures have you seen?
Dear Ms. Tulbure,
ReplyDeleteMy favorite solid figure is the cube because it's fun to draw. A cube has twelve edges and eight vertices. One famous example of a cube is the Rubik's cube game.
Your student,
Nikolas
Dear Nikolas,
DeleteI also enjoy the cube. I enjoy the cube because of its shape.
My favorite 3D solid figure is the sphere. The sphere fascinates me because it's the only shape that rolls.
Do you like the sphere?
What do you like about 3D shapes?
Sincerely,
Abbey (Jake's sister)
Dear Nikolas,
DeleteMy favorite solid figure is a sphere. It has zero faces, edges, and vertices. A famous example of a sphere is the planet Neptune. But my second favorite solid figure is a cube!

Dear Mrs. Tulbure,
ReplyDeleteMy favorite solid figure is a sphere. It is my favorite figure because it is round like a ball. A sphere has zero faces, zero edges, and zero vertices. It is round like a globe. I have a collection of globes.
My second favorite figure is a rectangular prism.
Your Student,
Danielle
Dear Ms. Tulbure,
ReplyDeleteMy favorite shape is a sphere. It is my favorite shape because it reminds me of a gum ball. It is my favorite type of candy and that is why I love spheres!
Goodbye,
Aliya, your 3rd grade student
@ Aliya,
DeleteMy favorite solid figure is also a sphere. When I think of a sphere, it reminds me of my favorite soccer ball.
Do you ever kick around a soccer ball?
Your friend,

Dear Ms.Tulbure,
ReplyDeleteMy favorite shape is a rectangular prism, because it is the most likely to be the shape of a board game. A rectangular prism was 6 faces, 12 vertices, 8 edges. The Washington Monument is an example of this shape.

Dear Ms. Tulbure,
ReplyDeleteThis post is amazing especially for your first post!
Our favorite 3D figure is square pyramid. It has 4 triangular faces and 1 square face. It has 8 edges and 5 vertices. Two famous examples are the pyramids in Egypt and the pyramid at the Lourve.
Mrs. Yollis' class has also recently been learning about solid figures.
Do you know how monstrous the Sphinx is?
Sincerely,
Grace and Annika
Dear Grace,
DeleteThis is some information about the Sphinx:
Height: 65 feet
Width: 20 feet
Length: 260 feet

Dear Ms. Tulbure,
ReplyDeleteMy favorite solid figure is a cube. The cube has 6 faces, 12 edges and 8 vertices.
A famous example is the Rubik's Cube. It is an amazing game, but very difficult to solve.
Did you know Erno Rubik is a Hungarian inventor?
The Rubik's Cube was his first invention. He invented in the spring of 1974, but it got approved and appeared at the end of 1977.
His other inventions was the Rubik's Magic, Rubik's Snakes and Rubik's Tower of Babel. The Tower of Babel was only sold in Hungary.

Gabe
Dear Ms. Tulbure,
ReplyDeleteMy favorite shape is a sphere because most sports inclued spheres. For example, basketball, baseball, soccer, ping pong, and tennis. My favorite sport that includes a sphere is basketball.
What is your favorite sport that includes a sphere?
Sincerely,
Jake and Abbey :D
Dear Mrs. Tulbure and class,
ReplyDeleteWe think a cube (also a rectangular prism) is the most important shape. It is our favorite solid figure because a lot of objects are cubic. For example, a brown shoe box is a rectangular prism, an interesting book, a computer screen, a case for a fire extinguisher, and of course something we use in school is the projector.
Our favorite solid figure has 6 faces, 12 edges, and 8 vertices.
The famous example of a cube/rectangular prism is part of The White House.
Does anybody else have another famous example of a cube?
Mrs. Ranney's students,
Charlotte and Alexandra
Dear Charlotte and Alexandra,
DeleteWe love that you posted on our new blog! The cube is one of our favorite solid figures as well! Wow, what interesting examples of rectangular prisms you have mentioned to us.
Some famous examples of cubes that we adore are: Rubik's Cube, a 1998 television set, the President's desk, and all the Harry Potter series.
What book series do you enjoy reading?
