enVision Math Common Core Kindergarten Answers Key Topic 12 Identify and Describe Shapes
Essential Question:
How can two- and three-dimensional shapes be identified and described?
Answer
A two-dimensional (2D) shape has only two measurements, such as length and height.
A square, triangle, and circle are all examples of a 2D shape.
However, a three-dimensional (3D) shape has three measurements, such as length, width, and height.
A cube, prism and cylinder are example of 3D shapes.
enVision STEM project: Pushing and Pulling Objects
Directions Read the character speech bubbles to students. Find Out! Have students investigate different kinds of wheels. Say: Not all wheels look alike, but they are all the same shape. Talk to your friends and relatives about the shape of a wheel and ask them how it can help when you need to push and pull objects. Journal: Make a Poster Have students make a poster that shows various objects with wheels. Have them draw up to 5 different kinds of objects that have wheels.
Answer:
Yes, students can investigate different kinds of wheels by recollecting means of transport like bus, car, bike and so on., while travelling.
Not all wheels look alike, but they are all the same shape.
With this we can bring the concept of circle shape to the students
Wheels are everywhere in our world today, in very obvious places like car, bus trucks etc., but also hidden inside everything from computer hard drives, dishwashers. Six thousand years ago, there weren’t any wheels at all. The rise of the wheel, from a basic turntable that helped people mold clay pots to a key component in hundreds of important invention owes everything to the simple and effective way it helps us capture and harness energy and transform forces. So we need wheels to push and pull the objects.

Pick a Project
A
Project A:
Answer:
Bone is specific to vertebrates, and originated as mineralization around the basal membrane of the throat or skin, giving rise to tooth-like structures and protective shields in animals with a soft cartilage-like endoskeleton. The bones gives the shape and posture to the body.
Steps to be followed for Dinosaur puzzles:
The primary material that you need for this project is corrugated cardboard or double layered cardboard.
The first thing that you need to do is find a template or draw the picture of Dinosaur.
Now that you have a template, you need to print it out in the size that you want.
Then attach the templates to the cardboard, you can use tape or a removable glue.
Then you need to mark the outline of each piece on the cardboard. You can do this by tracing each piece with a dark pen. You could also use a sharp object such as a knife or a needle to pierce through the template and into the cardboard.
Cut out the puzzle pieces and now comes the fun part i.e., putting the puzzle together.
B
PROJECT: B
Directions Say: You will choose one of these projects. Look at picture A. Think about this question: Where did all those bones come from? If you choose Project A, you will create dinosaur puzzles. Look at picture B. Think about this question: Would you rather design buildings or build them? If you choose Project B, you will design and build a structure.
C
Project C
Answer:
Depending on its size, it could be a pyramid, a clown’s hat, a slice of pie, a bird’s beak.
Depending on how they’re placed, they might suggest a mountain range or a tent encampment, a pine tree farm, or a schooner’s etc.,

Lesson 12.1 Two-Dimensional(2-D) and Three-Dimensional (3-D) Shapes
Answer:
Solid figures are identified according to the features that are unique to each type of solid. Specifically, one can observe the numbers of faces, edges, and vertices, as well as the shape of the base.
A plane horizontal surface with no depths is called the flat surface.
The following groups are different based upon their shape and structure.
Classified into 2 dimensional and 3 dimensional shapes.
Flat and Solid shapes.
Directions Say: Pick 6 shapes from a bag. Put the shapes into two groups. Tell how the groups are different. Then draw a picture of the shapes you put on each table.
