 First grade geometry involves several foundational concepts that are important as students begin to build their math skills. Students compare the attributes of shapes and identify how shapes are alike or different. They combine shapes to make more complex shapes. Students also build their conceptual understanding of fractions by identifying equal parts and dividing shapes into equal parts.

The most important geometric skill in 1st grade is the beginning of fraction exploration. Students identify and draw equal parts in everyday situations, such as any sharing situation. Have students share food and toys in equal parts. Any time fraction language is used, such as half, fourth, or quarter, have students verify that the part described is truly an equal part of a whole. Often in our everyday language, we use half to describe sharing two parts of something, but the two halves are not always exactly the same. Help your 1st-grade students identify these situations and reinforce the skill by pointing out that the parts are not truly halves unless they are equal parts of the same whole.

#### 1st Grade Geometry: Identifying Attributes

In this 1st-grade geometry lesson, students learn what attributes define a shape. For example, the number of sides defines a shape, but the color of a shape does not make it a particular shape. Then students use attributes to draw shapes.

#### What Makes a Shape?

Students look at a set of matching shapes and choose phrases that describe what makes that shape. For example, phrases students could choose to describe a set of triangles include closed and 3 sides. They would not choose striped or gray.

#### Draw Shapes

Students are asked to draw a shape based on a given attribute such as the number of sides or corners.

#### 1st Grade Geometry: halves, thirds and fourths

In this 1st-grade geometry lesson, students begin developing fraction concepts by making and identifying equal parts of a shape. Students learn the name of equal parts of shapes divided into halves, thirds, and fourths.

#### Identifying Equal Parts

Students determine if a square, rectangle or circle is divided into equal parts and how many equal parts there are.

#### Identifying Equal Parts with Mixed Shapes

Students identify shapes that are divided into equal parts.

#### Drawing Equal Parts - Halves

Students draw a line to divide a square, rectangle, or circle into two equal parts.

#### Drawing Equal Parts - Fourths

Students draw lies to divide a square, rectangle, or circle into four equal parts.

#### Drawing Equal Parts - Mixed

Students draw a line to divide a square, rectangle, or circle into two or four equal parts.
