https://padlet.com/tomazm02/1dau7qkrq8jm K.G.3 Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid"). en-us 2019-12-09 19:27:31 UTC 2025-04-11 13:29:56 UTC hello@padlet.com tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421829141 Students will be able to identify shapes based on if it is flat or solid instead of by how it looks.
ex. "That box is a cube and the poster on the wall is a square"

Students will tell the difference between a solid or flat shape.
ex. "The clock in our classroom is a circle because it is flat and the globe is a sphere because it is solid."]]> 2019-12-09 19:46:00 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421829141 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421835049 This powerpoint is a good resource to use when introducing the topic of
 2-D and 3-D shapes. It gives definitions and examples of each and allows for student involvement to sort shapes at the end. Even though not all Kindergarteners will be able to read, the pictures will help them understand the material and they may even be able to connect a word to how it is written.]]> 2019-12-09 19:55:04 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421835049 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421839845 This video is another good resource for introducing the topic of
2-D and 3-D shapes.

Where do you see solid shapes in our classroom?
Where have you seen flat and solid shapes outside of school?
What makes a shape solid or flat?
Can one object be both flat and solid?
Do we normally see more 2-D or 3-D shapes every day?]]> 2019-12-09 20:06:01 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421841440 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421842855 After the topic is introduced and defined, a helpful activity would be to gather items from the classroom and lay them out where students can easily see. There needs to be a good variety of 2-D and 3-D shapes. Some example for 2-D shapes are paper, posters, and folders (when closed). Some examples of 3-D shapes are a basketball, a clorax wipe container (or any cylinder), and a whiteboard eraser. Lay them out and mix them up so they are scattered. Allow students to come up and help sort the objects into the category of 2-D and 3-D all the while explaining why they decided to sort it that way.]]> 2019-12-09 20:07:52 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421842855 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421845034 This topic is very easy to relate to student experiences and lives because they are exposed to different shapes every day whether or not they realize it. You can use examples of balls from a sport that the students really like or even common toys they have played with at school. Using objects that the students are familiar with will help them understand and be able to think of their own examples of the shapes. ]]> 2019-12-09 20:11:50 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421845034 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421846583 These geometry shapes are a common tool in most classroom. They can be used to teach this topic by allowing students to see the difference of drawing a 2-D shape on a piece of paper and seeing it in 3-D by these blocks. Multiple sorting activities can be used with these blocks as well as letting the students explore and create another object using the 3-D shapes. ]]> 2019-12-09 20:15:06 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421846583 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421847791 To demonstrate 3-D shapes, materials such as clay/putty, base ten blocks, balls, and blocks can be used.]]> 2019-12-09 20:17:14 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421847791 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421848339 To help teach 2-D shapes activities such as tracing shapes in sand, making your own shape on paper, and using grid paper to make shapes can be useful. ]]> 2019-12-09 20:18:18 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421848339 tomazm02 https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421848942 This standard is the base for standards in future grades to build off of. In first grade, the standard building off of K.G.3 is 1.G.2, Compose 2-dimensional and 3-dimensional shapes to create a composite shapes, and compose new shapes from the composite shape. The information that is being added is taking the 2-D and 3-D shapes that they learned and taking them apart to make different shapes. For example, the students will learn how you can take a circle and create half and quarter circles within the whole. 

In Grade 2 (2.G.1), the standards build off and start to teach how to recognize different attributes of shapes such as a given number of angles or a given number of equal faces. 

In Grade 3 (3.G.1), the standards build off and teach about shapes that share attributes and are then placed in a category of their own. 
ex. Rectangles, squares, and rhombuses are all examples of quadrilaterals.

In Grade 4 (4.G.1, 4.G.2, and 4.G.3) all expand on learning about symmetry on 2-D shapes and identifying parallel and perpendicular lines on 2-D shapes.

An example of an assessment can be an activity where the students take pictures of objects and correctly glue them on a piece of paper under the correct section of 2-D or 3-D shape. Another example for assessment can be having students identify 2-D or 3-D shapes from a picture. The picture can be a photo of a bedroom with different objects laying around. The students can circle the 3-D shapes and put an "X" over the 2-D shapes. This will help the teacher see what students learned from the lesson taught.]]> 2019-12-09 20:32:56 UTC https://padlet.com/tomazm02/1dau7qkrq8jm/wish/421856250
