Description |
| MA.2.GR.1.1: | Identify and draw two-dimensional figures based on their defining attributes. Figures are limited to triangles, rectangles, squares, pentagons, hexagons and octagons.Clarifications:
Clarification 1: Within this benchmark, the expectation includes the use of rulers and straight edges. |
|
| MA.2.GR.1.2: | Categorize two-dimensional figures based on the number and length of sides, number of vertices, whether they are closed or not and whether the edges are curved or straight.Clarifications:
Clarification 1: Instruction focuses on using formal and informal language to describe defining attributes when categorizing. |
|
| MA.2.GR.1.3: | Identify line(s) of symmetry for a two-dimensional figure.Clarifications:
Clarification 1: Instruction focuses on the connection between partitioning two-dimensional figures and symmetry.
Clarification 2: Problem types include being given an image and determining whether a given line is a line of symmetry or not.

Description |
| Capitol Geometry - Lesson 2: | In this lesson, students will continue learning about the history of the Florida State Capitol building, through a grade-level appropriate reading. They will then be provided with a diagram of the glass dome from the Old Capitol. After direct instruction on categorizing two-dimensional figures based on defining attributes, they will use the diagram of the glass dome and categorize the figures.
This is lesson 2 of 3 in a mini-unit integrating civics and math. |
| Capitol Geometry - Lesson 3: | In this lesson, students will continue to learn about the history of the Florida State Capitol building, specifically the history of the stained glass sub dome, through a grade-level appropriate reading. They will then be provided with a diagram of the glass dome from the Old Capitol. After direct instruction on identifying lines of symmetry in two-dimensional figures, they will use the diagram of the glass dome and identify lines of symmetry within the two-dimensional figures used in the piece.
This is lesson 3 of 3 in a mini-unit integrating civics and math. |

| ABC Symmetry: | Students will explore the concept of line symmetry in this lesson. Students will explore two-dimensional pictures and decide whether or not each image has symmetry. Students will also fold pre-cut capital letters to decide whether or not each letter has symmetry. |
| It's All About the Shapes: | The teacher reads The Greedy Triangle to the class to explore attributes of figures. As the teacher reads, the students create the shapes in the book using geoboards. Students follow up their exploration with a card sort. The students create Frayer Models in their journals using information they discovered during the lesson. |
| Symmetrical Solutions: | Students will use paper cutout and geoboards to find and create lines of symmetry. Students will have the opportunity to work with a partner and independently. |
