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.

Is it Still a Rectangle?:

Students discuss the defining and non-defining attributes of rectangles.

Type: Formative Assessment

Is it Plane or Solid?:

Students examine a rectangle and a rectangular prism to discuss the similarities and differences.

Type: Formative Assessment

Draw Triangles:

Students draw two triangles and are prompted to describe the triangles in terms of defining attributes.

Type: Formative Assessment

Fill in the Missing Part:

Students view a composite shape with a missing piece and identify shapes that can fill in the space.

Type: Formative Assessment

Cubes and Prisms:

Students compare a cube to a rectangular prism and discuss the similarities and differences.

Type: Formative Assessment

Composing a Trapezoid:

Students use triangles to compose a trapezoid.

Type: Formative Assessment

Compose Shapes with Triangles and a Trapezoid:

Students compose new shapes from equilateral triangles and a trapezoid.

Type: Formative Assessment

Compose Shapes With Triangles:

Students join right triangles together to compose a rectangle and then use the rectangle to compose a new shape. Students describe this new shape made from the composite shape.

Type: Formative Assessment

Compose a Hexagon:

Students use triangles to compose a hexagon.

Type: Formative Assessment

Comparing a Cylinder to a Circle:

Students compare the outline of the circular base of a cylinder to the cylinder itself.

Type: Formative Assessment

Attributes of a Hexagon:

Students draw two hexagons and are asked to justify their drawings.

Type: Formative Assessment

Compare Hexagons:

Students compare two hexagons and describe how they are alike and how they are different.

Type: Formative Assessment

Building With Three Dimensional Shapes:

Students use different three dimensional shapes to compose a composite shape.

 

Note: This task includes the use of triangular prisms.

Type: Formative Assessment

Lesson Plans

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

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

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

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.

Problem-Solving Tasks

Overlapping Rectangles:

The purpose of this task is to give students an opportunity to compose and decompose polygons to make rectangles. This is a challenging problem for first graders and it would be inappropriate to use it as an assessment.

Type: Problem-Solving Task

Make Your Own Puzzle:

The purpose of this task is to give students a hands-on experience with composing and decomposing geometric figures and is meant as an instructional task.

Type: Problem-Solving Task

Counting Squares:

The purpose of this task is to give students an opportunity to compose and decompose squares. This is a challenging problem for first graders and it would be inappropriate to use it as an assessment. However, if presented as a brainteaser it can be useful for giving the students practice in recognizing squares and stimulate interest as students compete to try to find the most squares.
