Access Points

MA.1.GR.1.AP.1
Sort and identify two- or three-dimensional figures based on their defining attributes. (e.g., number of sides, vertices, edges, faces, etc., rather than color, orientation or size). Figures are limited to circles, semi-circles, triangles, rectangles, squares, trapezoids, hexagons, spheres, cubes, rectangular prisms, cones and cylinders.
MA.1.GR.1.AP.2
Produce two-dimensional figures when given defining attributes. Figures are limited to triangles, rectangles and squares.
MA.1.GR.1.AP.3
Recognize that different figures can be formed by putting together smaller two- or three-dimensional figures and that smaller figures can be formed by taking apart larger two- or three-dimensional figures. Figures are limited to semi-circles, triangles, rectangles, squares, trapezoids, hexagons, cubes, rectangular prisms, cones and cylinders.
MA.1.GR.1.AP.4
Explore real-world objects with parts that can be modeled by a given two- or three-dimensional figure. Figures are limited to semi-circles, triangles, rectangles, squares and hexagons, spheres, cubes, rectangular prisms, cones and cylinders.

Lesson Plans

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.

Type: Lesson Plan

Are You a Responsible Sorter and Citizen?:

Students will identify and sort three-dimensional figures by their attributes while demonstrating and identifying qualities of responsible citizenship.

Type: Lesson Plan

Understanding Polygons:

This is a simple and fun activity that is great to incorporate into your geometry unit. As you read "The Greedy Triangle" aloud, the students "create" each shape with marshmallows and pretzel sticks - as you are reading the story, they complete a sheet in which they write the name of each shape, draw the shape, and record the number of sides and vertices each shape has.

Type: Lesson Plan

Puzzled by Pattern Blocks!:

In this lesson, the students will use two-dimensional pattern blocks to compose new shapes and fill in composite outlines of shapes.

Type: Lesson Plan

Shape Identifying and Sketching:

In this lesson students will describe attributes of triangles, rectangles, squares, and hexagons and identify these shapes by their attributes. Given the name of one of these shapes, students will use their knowledge of the shape's attributes to represent the shape with a sketch.

Type: Lesson Plan

Life Jackets:

In this Model Eliciting Activity, MEA, the students are to decide what criteria is the most important for a company to consider when choosing life jackets. Students will use tally charts with data about comfort and visibility as well as information provided on 3D figures that can be used to model the life jackets.

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.

Type: Lesson Plan

The Greedy Shapes:

The lesson Greedy Shapes will give opportunities for students to use their knowledge of attributes of shapes (number of sides, sides of equal length, number of vertices, shapes that are closed or not, curved or straight edges) to sketch triangles, rectangles, squares, and hexagons. 

Type: Lesson Plan

Being Shapely!:

In this lesson, students will work collaboratively to identify and sketch shapes with defining and non-defining attributes.

Type: Lesson Plan

Fun with Shapes:

In this lesson students explore the composing of new shapes from other two-dimensional shapes. The students will utilize math benchmarks as they analyze math solutions and explain their solutions. Since the lesson uses composing, it is also a good lesson to use to show decomposing (taking a shape apart).

Type: Lesson Plan

Quilt Squares:

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.

To learn more about MEA’s visit: https://www.cpalms.org/cpalms/mea.aspx

Students will use pattern blocks to create a quilt square for the Quick Quilters Society. They will have to consider information on a data chart to help them create their squares. They will have to add up the cost to make their square, too.

Type: Lesson Plan

Shape Creator:

In this lesson, students will be taking their knowledge of two-dimensional shapes and applying it to recognizing combinations of shapes in real-world objects. They will also sketch these shapes and use them to model real-world objects.

Type: Lesson Plan

Composite Creature:

The students will use pattern blocks to build and draw new composite geometric shapes, ultimately using composite shapes to form a creature.

Type: Lesson Plan

I'll Share With You:

This lesson focuses on the beginning understanding of fractions through fair-sharing. Students will partition circles and rectangles into 2 and 4 equal-sized parts and be able to describe these parts using appropriate language such as halves and fourths.
