K.G.4

K.G.4.

Essential Vocabulary

 * ===difference, similarities, attribute, compare, sides, vertices/corners, long, longer, short, shorter ===

Sample Assessments

 * describe attributes of two and three dimensional shapes
 * compare and contrast a two dimensional shape with a three dimensional shape
 * recognize that three dimensional shapes are composed of two dimensional shapes

Differentiation

 * Use 2D and 3D shapes to find objects in the room of that same shape and then describe similarities and differences.
 * Go on a shape scavenger hunt.

Intervention:

 * Small group/show a 2D and 3D shape-have students explain likenesses and differences.

Enrichment:

 * AIG-brainstorm objects in the environment that are 2D and 3D and explain how they are alike and different.

<span style="font-family: Arial,Helvetica,sans-serif;">Notes and Additional Information
<span style="font-family: Arial,Helvetica,sans-serif;">Students relate one shape to another as they note similarities and differences between and among 2-D and 3-D <span style="font-family: Arial,Helvetica,sans-serif;">shapes using informal language. <span style="font-family: Arial,Helvetica,sans-serif;">For example, when comparing a triangle and a square, they note that they both have sides, but the triangle has 3 <span style="font-family: Arial,Helvetica,sans-serif;">sides while the square has 4. Or, when building in the Block Center, they notice that the faces on the cube are all <span style="font-family: Arial,Helvetica,sans-serif;">square shapes.
