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.

Type: Lesson Plan

In this integrated lesson plan, students are tasked with finding the Florida state flag by following directions from a partner who names the 2D or 3D shape it is hidden beneath. 

Type: Lesson Plan

This lesson is designed to explore the attributes of rectangles using a variety of examples in different sizes, orientations, and colors and non-examples that lack one or more defining attributes of a rectangle.

Type: Lesson Plan

The purpose of this lesson is for students to examine defining and non-defining attributes of 3-dimensional figures. Students compare and contrast various representations of 3-dimensional figures (including real-world objects) to determine what the solid must have, compared to what it might have. This exploration is also supported by sorting 3-dimensional figures.

Type: Lesson Plan

This lesson is an introduction to 3-dimensional shapes. The lessons uses food to help students explore the attributes of those shapes. Then, of course, the students get to eat them!

Type: Lesson Plan

In this lesson, students will discover the names of different two-dimensional and three-dimensional shapes and their attributes through activities such as playing "Hide and Seek" with shapes and playing "Hot and Cold" to find shapes in the classroom.

Type: Lesson Plan

The students will identify and describe shapes (squares, circles, triangles, and rectangles, ) regardless of their orientations or overall size by becoming detectives and going on a "hunt" to find the given shapes.

Type: Lesson Plan

In this lesson, students will learn to identify, describe, and sort two-dimensional shapes (circles, triangles, rectangles, and squares) through music, movement, and hands-on exploration.

Type: Lesson Plan

In this hands-on lesson, students will be challenged to demonstrate their understanding of shapes to combine smaller two-dimensional shapes to form larger composite shapes. The lesson culminates with students using triangles, rectangles, and squares to form a "robot".

Type: Lesson Plan

In this lesson students will compare two-dimensional shapes to other two- dimensional shapes (circle, square, triangle, and rectangle) and three-dimensional shapes to other three-dimensional shapes (cone, cylinder, sphere, cube) by differentiating them according to attributes. Students describe attributes of shapes by exploring real world objects.

Type: Lesson Plan

The lesson focus will be a kinesthetic approach to understanding relative positions in the environment. The lesson begins with a critical input experience, as students move around their surrounding, looking for shapes around them. Basic shapes include circle, square, triangle, rectangle. Students will explore shapes in the real world setting. As the lesson progresses, students will learn to describe the position of objects in relation to their own bodies using positional language such as: left/right, in front of/behind, apart and above/below. The lesson will be followed by guided instruction portion using hands-on manipulatives to transfer learned skills. The learning sequence will conclude with an informal assessment of student understanding.

Type: Lesson Plan

The students will be working in whole group, small group and individually to discover measurable attributes of objects and sort the objects into categories. Students will also count and compare the number of objects in each category. 

Type: Lesson Plan

Students will go on a shape hunt in the classroom or designated area. During the shape hunt, students will find real-world objects that can be modeled by two- and three-dimensional figures. After the shape hunt, students will use Timed-Pair-Share to explain to peers what objects they found and their relative positions.

Type: Lesson Plan

In this lesson, kindergarten students will learn to sort objects familiar to them by different attributes. They will justify their decisions for classification when objects have more than one similar characteristic.

Type: Lesson Plan

In this MEA, students will sort recycling material based on the shape, name the shapes, and decide on what recycling bin would be the best for the city to choose. Students will write and draw a picture describing which recycling bin they chose.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom.

Type: Lesson Plan

Students will help Mr. Bob Fitness choose a piece of sports equipment for his new store. Students will work with three-dimensional shapes and determine a procedure in choosing the equipment.

Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. MEAs resemble engineering problems and encourage students to create solutions in the form of mathematical and scientific models. Students work in teams to apply their knowledge of science and mathematics to solve an open-ended problem, while considering constraints and tradeoffs. Students integrate their ELA skills into MEAs as they are asked to clearly document their thought process. MEAs follow a problem-based, student centered approach to learning, where students are encouraged to grapple with the problem while the teacher acts as a facilitator.
