Miss Burns introduces first-grade students to geometry, focusing on defining and non-defining attributes of shapes. The lesson involves sorting shapes based on these attributes, identifying triangles and rhombuses, and understanding that color, size, and position are non-defining attributes. Students are encouraged to practice sorting shapes at home and complete a Microsoft form activity.

What is the main focus of today's lesson?

• Exploring historical events

• Sorting shapes by their attributes

• Studying the solar system

• Learning about numbers

Which of the following is a defining attribute of a square?

• Four equal sides

• Color

• Position

• Size

What makes a triangle different from a rhombus?

• Triangles have curved sides

• Triangles are always blue

• Triangles have three sides, while rhombuses have four

• Rhombuses are larger than triangles

How can you identify a rhombus?

• It has three sides

• It is always red

• It has four equal sides and vertices

• It is a circle

Why does the color of a shape not matter when identifying it?

• Color is a defining attribute

• Color changes the shape's name

• Color is a non-defining attribute

• Color determines the shape's size

What should you consider when sorting shapes?

• The position and texture

• The material and weight

• The color and size

• The number of sides and vertices

Which of the following is NOT a defining attribute of a triangle?

• Color

• Three sides

• Straight sides

• Three vertices

What is a common mistake when identifying shapes?

• Considering the color and size

• Counting the sides and vertices

• Ensuring the vertices are equal

• Checking if the sides are straight

What should you do if a shape has a curved side?

• Consider it a square

• Identify it as a triangle

• Identify it as a rhombus

• Recognize it is not a triangle

What activity is suggested for exploring shapes at home?

• Building shapes with blocks

• Painting shapes in different colors

• Sorting household objects by shape

• Drawing shapes on paper
