Standard 1: Identify and analyze two-dimensional figures and identify lines of symmetry.

Students are asked to draw a triangle and justify his or her drawn shape. Then students are shown a figure that is not a triangle, but that has three sides and asked to determine if the figure on the worksheet is a triangle.

Type: Formative Assessment

Students are asked to draw a five-sided figure and name the figure.

Type: Formative Assessment

Students are asked to describe attributes shared by three shapes and to identify a larger category into which these shapes can be placed.

Type: Formative Assessment

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.

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.

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.

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.

Type: Lesson Plan

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.

Type: Lesson Plan

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.

Type: Lesson Plan

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.  

Type: Lesson Plan

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.

Type: Lesson Plan

Learn how to recognize and draw triangles, pentagons and hexagons using the shapes' attributes in this space-themed, interactive tutorial.

This lesson is designed to introduce students to quadrilaterals and the terms and properties associated with quadrilaterals. This lesson provides links to discussions and activities related to quadrilaterals as well as suggested ways to integrate them into the lesson. Finally, the lesson provides links to follow-up lessons designed for use in succession with the current one.
