| Using Machine Learning and Computational Thinking to Train an AI Model: | Students will explore Artificial Intelligence (AI) and use computational thinking and Machine Learning (ML) to 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 computational thinking 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 grades 3-5 to apply math and science content knowledge while exploring and using computational thinking as they think like Computer Engineers and reflect on potential career paths. |
| Shape Up Your Civility: | Students will be able to listen and cooperate with one another in replicating geometric designs without seeing them and relate this to how citizens demonstrate civility and cooperation to accomplish a common goal. |
| Design a New State Seal: | Students will use their knowledge of Florida symbols, individuals, documents, and events to create a new state seal. Students will incorporate the study of various lines and quadrilaterals into their design. They will justify what symbols they picked and how they fit into the requirements of the project in this model eliciting activity. 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. |
| Artistic Alley: | Students will use their knowledge of how to identify quadrilaterals and how to analyze data to determine a ranking for the best paver designs for a driveway. In this MEA, students will deepen their understanding of the attributes of parallelograms, rectangles, squares, trapezoids and quadrilaterals that do not belong to any of these categories.

| 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. |
| Quadrilateral Quest: | In this lesson, students categorize shapes identifying the attributes of quadrilaterals. |
| Same Perimeter, Different Area: | In this lesson, students are presented with a problem that requires them to create rectangles with the same perimeter but different areas. Students also search for relationships among the perimeters and areas of different rectangles and find which characteristics produce a rectangle with the greatest area. |
| Pretzel Quadrilaterals: | This lesson helps students to realize that quadrilaterals have identifying attributes that define them. Students should also discover that a quadrilateral can have multiple names based on the attributes of a category. |
| Snowflake Geometry: No Two Alike!: | In this lesson students will make snowflakes, promoting creativity and self-expression, and use them to identify geometric terms. It also gives them an opportunity to follow a sequenced set of instructions for a given outcome. |
| Raja Rangoli: | Rangoli is a traditional Indian art that is used in decorating the entrance of the house to welcome guests. In this activity students will use the concept of lines of symmetry to select the best rangoli design for a school event.
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 processes. 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.

| Angles All Around Us: | This is a lesson that introduces right, acute, obtuse, reflex, straight angles in a fun and challenging way. |
| Arrays Show the Way to the Multiplication Chart: | This is an introductory lesson to explore the use of arrays to solve multiplication problems. Students build arrays and save the arrays in a class Multiplication Chart. They learn to use arrays to find products and factors, and by placing them in the Multiplication Chart, they learn how to read the chart. They learn how to write equations to represent situations that are modeled with arrays. An overall theme is the organization of the multiplication chart and how it includes arrays within. |
| Points, Lines, and Angles, Oh My!: | In this lesson, students work to identify points, lines, line segments, rays, angles and perpendicular and parallel lines.

Students will participate in a Building Block Scavenger Hunt, using paper and pencil to draw examples of specified terms that they find outside of the math classroom. The students will compose a poster to display their images of the required terms. |
