*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.

*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! :)

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.

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.

Also, I think students should learn about the x and y axis in the upper elementary grades.]]> 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450217 Meredith Richards rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450218 I think that some key ideas for geometry in elementary grades are shapes, 3D shapes, measurements, points, and also lines.]]> 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450218 Abi Davis- Key ideas in geometry. rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450219 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. ]]> 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450219 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. rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450220 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450220 Jennifer Stoltz-Cuevas rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450221 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.]]> 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450221 Jessica Towery rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450222 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. ]]> 2019-07-27 17:28:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450222 Relation to Real Life rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450277 I think it's important to choose activities that make geometry more relevant to young students. For example, instead of always using blocks or handouts that have shapes printed on them, use objects from around the classroom, such as a globe of the earth, a desk top, bookshelves, books, and other objects. This gives students an understanding of how geometry is all around us and how it can be used. It also makes the activities a bit more engaging for students.

Students are given a paper with half of an image with a line down the middle and must use the mirror to draw the other side of the image. This would be a fun activity for students and could be part of a whole lesson introducing symmetry.

A fun, interactive activity to help teach 2D and 3D concepts is to have student construct shapes using play-doh and toothpicks. You could have student create a list of attributes for each to justify what makes their construction a given 2D or 3D shape.]]> 2019-07-27 17:45:45 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450633 The Pythagorean Theorem rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450797 One of the most important geometric concepts is the Pythagorean Theorem. Students tend to have trouble conceptualizing the theorem since it can be a rather abstract concept. Using a model such as the one posted below can help students conceptualize it better.]]> 2019-07-27 17:50:24 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450797 The Coordinate Plane rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450880 Another difficult geometric concept is the coordinate plane. Students can better understand it if it is related to something a bit less abstract. A great activity to help students come to understand the purpose and properties of the coordinate plane is to have them create a map of their school on the coordinate plane. Students can use numbers in ordered pairs to indicate locations in the different quadrants.]]> 2019-07-27 17:54:40 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450880 Line Segments rlh7647 https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450987 You can use geoboards and rubber bands to teach the coordinate plane, about midpoints, and about line segments.]]> 2019-07-27 17:59:23 UTC https://padlet.com/rlh7647/iwtsa4q2hx5v/wish/372450987
