I think the key ideas of geometry include things such as shapes, symmetry, angles, and measurements involving each of these. Each of these concepts will be thought through more in depth as they progress through their education. Students will build on these until they are prepared with what seems to be the basis of geometry, giving them a good understanding before diving into middle school which will have much more complex ideas.

I think that some of the key ideas in geometry that should be covered in the elementary grades include shapes (2D and 3D), types of lines (segments, rays, parallel, perpendicular, etc..) types of angles, classifying triangles, working with protractors and finding measurement of angles. Students should be introduced to learning about graphs and the different types of graphs, collecting data and how to put all that together. I"m going to "steal" as well the vocabulary piece and learning about correct geometry vocabulary.

I think some of the key ideas for geometry in elementary education include making students aware of 2D shapes, 3D shapes, the different types of lines (segment/ray), angles, parallel, perpendicular, intersecting, and points on a plane.

I think that some of the ideas that should be covered in elementary geometry should include things that will allow students to get a general idea of what geometry is. For example, shapes (2D and 3D) and being able to relate shapes to everyday things, there should be an introduction to measurement, degrees, lines, and formulas, all the things like this that will help them when they get to higher grades so they have something to relate to.

I think the key ideas in geometry that should be covered are those that will create a foundation for the work in geometry that students will face in upper grades. I believe that students should begin to learn about graphs, why they are important and how they can be used. I also think that shapes and lines are very important to be covered, since they will be used in all forms of geometry, and students will eventually use lines to create graphs and interpret data.

I think that some key ideas for geometry in elementary grades are shapes, 3D shapes, measurements, points, and also lines.

I think some of the key ideas that should be covered in the elementary grades are 2D and 3D shapes, measurements, lines, and angles. Also, I think students should learn about the x and y axis in the upper elementary grades.

I believe in when exploring geometry in elementary school it is important to start with a strong foundation. In my opinion this foundation should start with learning and understanding vocabulary.  Teachers should model using appropriate vocabulary beginning at the early grades to prevent misconceptions. For example, we as teachers should not use terms such a “diamond shape” to describe something. We should use a more proper term such as polygon or rhombus.

Moving on from vocabulary I believe basics such as how to measure area and parameter, how to graph,  and how to measure angles should also be covered in elementary grades.

Please use this Padlet to respond to this question.  Your answer to this question is not expected to be final or definitive. I expect your ideas will change, expand, and deepen throughout the module.  Be creative.  You may attach files,  add links, include pictures, record audio or doodle on the screen.

I think some of the key ideas of geometry that should be covered in elementary grades are all about shapes, measurements, beginners formula, and how to graph things on x and y axis'.

I really love geometry. It's an area of mathematics that has always just made sense to me, so I am excited to teach it. To gain some insight, I pulled up NC's Mathematics Standard Course of Study. I used the state math standards to compile the following list for key geometric concepts at the elementary level:

Identify, analyze, compare, contrast, create and compose  2D and 3D shapes and reason with their attributes, including but not limited to: partitioning, modeling, orientation, dilation, mapping, and decomposition.

Classify and compare shapes based on lines and angels in 2D figures, such as drawing and identifying lines, points, line segments, rays, angles, vertices, and perpendicular and parallel lines and their relationships.

Measure angels using degrees and classify them based on their measurements.

Use formulas to calculate volume, area, and surface area. Understand and apply the Pythagorean Theorem.

Recognize and identify properties of symmetry. Recognize parallel and intersecting lines.

Identify congruent shapes after transformation using translation, rotation, dilation, and reflection.

Understand properties of the coordinate plane and identify and interpret the x and y coordinates  and their given axis’s to understand relationships between points.

Classify quadrilaterals in a hierarchy based on properties.

Study real life problems involving area, surface area, and volume.

The key ideas for geometry that should be included/covered in elementary grade should include:
*Name of all shapes
*Being able to recreate these shapes 2D and 3D
*How to measure lines, angles, etc.
*How to graph points on the coordinates and knowing where x and y axis are (for 5th and up)
*Understanding different lines: perpendicular, parallel, etc.
*I really like that Brittni put "proper vocabulary" and I'm going to "steal" this and put it into my group as well! :)

I believe the keys ideas that should be covered regarding geometry are the following:
*Names of shapes and their properties.
*How to measure angles using protractor, what degrees are, types of angles and how different angles can be used to find a missing degree (i.e. when you have a straight line, 180 degrees, and one angle is 80 degrees and the other angle is a variable representing the missing number).
*Knowing the difference between dimensions of shapes (i.e. 1D, 2D, and 3D). Having students being able to make, draw, and analyze these shapes as well as recognize them.
* Vocabulary such as line, plot, ray, angle, degrees, and much more.
* Using real world applications to measure students understanding of the content area in a formative assessment.
