Unit Overview and Enduring Understandings
This Unit centers on exploring two-dimensional (2D) and three-dimensional (3D) shapes, along with understanding their attributes and partitioning methods. Students engage in activities that help them describe and draw various 2D shapes like squares, circles, triangles, rectangles, and polygons, as well as 3D shapes such as cubes, spheres, cones, cylinders, and pyramids. They learn to distinguish between 2D and 3D shapes based on their properties and characteristics. Sorting activities based on attributes such as sides, corners, and types of lines help students classify shapes effectively. Additionally, students explore partitioning 2D shapes into equal parts, focusing on halves and fourths, and understanding how shapes can be divided evenly. Through hands-on activities, visual representations, and interactive lessons, teachers guide students to develop a solid understanding of geometric shapes and their properties, preparing them for more advanced concepts in geometry.

ENDURING UNDERSTANDINGS:
What key concepts will students grasp by the end of the unit? "Students will understand that..."
1. Two-dimensional shapes are flat and have only length and width, while three-dimensional shapes have depth in addition to length and width.
2. Describing and drawing shapes involves recognizing their sides, corners, types of lines, and other defining features.
3. Sorting shapes by attributes such as number of sides, types of angles, or presence of symmetry helps us classify and categorize shapes accurately.
4. Partitioning 2D shapes into equal parts, such as halves and fourths, requires dividing them into equal sections to understand fractions and symmetry.
5. Geometric shapes are fundamental to understanding structures, patterns, and spatial relationships in our surroundings, from buildings to everyday objects.

Conceptual Understanding
1.G.A.1- Distinguish between defining attributes (triangles are closed and 3 sided) versus non-defining attributes (color, orientation, overall size) for two-dimensional shapes; build and draw shapes that possess defining attributes.

Module 14:

A cube, cone, cylinder, sphere, and rectangular prism are all solid shapes.

Solid shapes have faces, edges, and vertices.

Some solid shapes can roll, slide, or stack.

Some shapes have flat faces, some have curved faces, and some have both.

Solid shapes can be sorted by what they look like or what they can do.

We can find and name solid shapes in real-life objects.

Module 15:

A two-dimensional shape is flat and can be closed with straight or curved sides.

Sides are straight or curved lines, and corners (called vertices) are where sides meet.

Shapes like triangles, rectangles, and hexagons have straight sides and corners.

A circle is a flat shape with no straight sides or corners—it’s made of one curved line.

Shapes can have different numbers of sides and corners.

Some shapes have all sides equal, like a square.

We can sort and compare shapes based on their sides, corners, and lengths.

Shapes can be put together or taken apart to make new shapes.

Module 16:

A whole can be split into equal parts.

Two equal parts make halves, and four equal parts make fourths or quarters.

More equal parts mean smaller pieces.

We use fractions to show fair shares.

We can find halves and fourths in real life, like cutting food or folding paper.

Application
1.G.A.2- Compose two-dimensional shapes or three-dimensional shapes to create a composite shape.

1.G.A.3- Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters. Describe the whole as two of, or four of the shares. Understand that decomposing into more equal shares creates smaller shares.
TSWBAT compose/ create 2-D and 3-D shapes with at least 90% accuracy.

TSWBAT partition circles and rectangles into two or four equal shares with at least 90% accuracy.

Procedural Skills and Fluency
1.OA.A.1- Use addition and subtraction within 20 to solve word problems with unknowns in all positions (e.g., by using objects, drawings, and/or equations with a symbol for the unknown number to represent the problem).


1.NBT.A.1- Count to 120 by 1's, 2's, and 10's starting at any number less than 100. In this range, read and write numerals and represent a number of objects with a written numeral.

1.NBT.C.5-Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count.

1.OA.C.5- Relate counting to addition and subtraction (e.g., by using counting on 2 to add 2).

Considerations:
When teaching Unit 5, teachers should keep several key considerations in mind for effective instruction:

1. It is essential to introduce shapes through hands-on activities and visual aids that allow students to explore and manipulate different 2D and 3D shapes.
2. Teachers should emphasize descriptive language when discussing shapes, encouraging students to articulate characteristics such as sides, corners, and types of lines.
3. Sorting activities based on attributes help students classify shapes effectively, reinforcing their understanding of shape properties.
4. Teachers should guide students through partitioning 2D shapes into equal parts like halves and fourths. This enhances their grasp of basic fractions and geometric symmetry.
5. Differentiate instruction to accommodate diverse learning styles. It ensures that all students engage meaningfully with geometric concepts.
6. Provide regular assessments and feedbacks. These are vital to monitor progress and adjust teaching strategies, ensuring students develop a solid foundation in geometry and spatial reasoning skills.
