Lesson seeds are ideas that can be used to build a lesson aligned to the CCSS. Lesson seeds are not meant to be all-inclusive, nor are they substitutes for instruction. When developing lessons from these seeds, teachers must consider the needs of all learners. It is also important to build checkpoints into the lessons where appropriate formative assessment will inform a teachers instructional pacing and delivery.
In this unit, Prekindergarten students identify and describe two-dimensional shapes (circles, triangle, rectangles; including a square which is a special rectangle) by observing, touching, cutting, combining, folding, drawing, and/or copying them. Students can also create shapes with their bodies. Since their environment is made up of shapes, students should learn to identify shapes by both sight and touch. It is important for students to participate in active experiences which expose them to a great variety of shapes, engaging in motivating tasks that include both examples and non-examples of shapes. Sorting shapes by applying real-life experiences is also a critical skill in this unit. This includes students grouping squares and rectangles together and understanding that a square is a special kind of rectangle, as well as the ability to explain their groupings. It is not necessary for students to name the shapes or even identify attributes at this time. However, it is important to expose students to the correct geometric terms for shapes. They should be given opportunities to identify shapes by both name and appearance.
Focus Standards (Listed as Examples of Opportunities for In-Depth Focus in the PARCC Content Framework documents for Grades 3-8):

Fluency Expectations and Examples of Culminating Standards:
Interdisciplinary connections fall into a number of related categories:
Sample Assessment Items: The items included in this component will be aligned to the standards in the unit and will include:
congruent: having the same size and shape, but not necessarily the same orientation. All corresponding parts of congruent figures have the same measure. Examples: length, height, and weight
similar: having the same shape but not necessarily the same size, and not necessarily the same orientation.
examples and non-examples of shapes: Examples are polygons that are all the same shape but may be different sizes and orientations, while non-examples are shapes that are different from the type named
positional relationships: comparing objects or shapes by their placement to each other. Descriptive words would include above, below, next to, in front of, behind, near, far, beside, etc
