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 |
| Exploring Machine Learning to Train an AI Model: | Students will explore Artificial Intelligence (AI) and Machine Learning (ML) and pretrain a model to recognize and identify objects, including geometric shapes and aircraft. They will used unplugged activities to mimic sorting and classification of the objects using their prior knowledge and then make connections to human learning and Machine Learning. Students will then problem solve and propose solutions using an iterative process to improve the ML model to better recognize the objects. This lesson is an integrated Computer Science, Science and Math lesson designed for students in K-2 to apply math and science content knowledge while exploring and using computational thinking like people in Computer Science careers do. |
| 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. |

They will then be provided with a diagram of the glass dome from the Old Capitol. After direct instruction on identifying two-dimensional figures, they will use the diagram of the glass dome and identify the two-dimensional figures used in the piece.

| Attributes of 2D Figures: | In this lesson, students will identify and categorize pentagons, hexagons, and octagons based on defining attributes. Students will sort based on closed, straight sides, number of sides, and number of vertices. |
| 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. |
| Three Billy Goats Gruff Build a Bridge - An Engineering Design Challenge: | This Engineering Design Challenge is intended to help students apply the concepts of force as they build bridges to hold the greatest load. It is also intended to help students apply the concepts of money as they strive to construct the most cost effective bridge. It is not intended as an initial introduction to these concepts. |
| 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. |
