Flashcard 1: Which option names the shape with defining attributes: closed figure with $4$ equal sides?

Answer: Square. Only squares have all $4$ sides equal and are closed.

Flashcard 2: Which option stays the same for every triangle: $3$ sides or pointing up?

Answer: $3$ sides. All triangles must have $3$ sides; direction can vary.

Flashcard 3: Identify the shape: a closed shape with $4$ equal sides and $4$ corners.

Answer: Square. Only squares have all sides equal with $4$ corners.

Flashcard 4: Identify the defining attribute: Does a square need $4$ equal sides or does it need to be blue?

Answer: It needs $4$ equal sides. All sides being equal defines a square.

Flashcard 5: Which option is a triangle: a closed shape with $3$ sides, or an open shape with $3$ sides?

Answer: Circle. Only circles have no straight sides or corners.

Flashcard 7: Which attribute should you keep to draw a triangle correctly: $3$ straight sides or any color?

Answer: $3$ straight sides. Number of sides defines the shape; color is optional.

Flashcard 8: What is a defining attribute of a square?

Answer: A square has $4$ equal sides and $4$ corners. Equal sides distinguish squares from other rectangles.

Flashcard 9: What is a defining attribute of a triangle in 1st grade geometry?

Answer: A triangle is closed and has exactly $3$ straight sides. These features must be present for any shape to be a triangle.

Flashcard 10: Which attribute is defining for a triangle: $3$ straight sides or the color red?

Answer: Sides. Triangles are defined by having exactly $3$ sides.

Flashcard 12: Which word names a non-defining attribute: orientation or being closed?

Answer: Orientation. A shape's position doesn't change what shape it is.

Flashcard 13: Which attribute is non-defining for a shape: size or being closed?

Answer: Size is non-defining. A shape stays the same whether big or small.

Flashcard 14: Which statement is correct: A square must have $4$ sides, or a square must be upright?

Answer: A square must have $4$ sides. Squares always have $4$ sides; position/orientation varies.

Answer: Closed. Shapes must connect all the way around.

Flashcard 31: Which option is a circle: a shape with $0$ corners, or a shape with $4$ corners?

Answer: A shape with $0$ corners. Only circles have no corners or straight edges.

Flashcard 32: Which option stays the same for every circle: round shape or being green?

Answer: Round shape. All circles must be round; color can vary.

Flashcard 33: Choose the word that means an attribute that must be true for the shape: defining or non-defining?

Answer: Defining. These attributes are required for a shape to exist.

Flashcard 34: Which attribute is defining for a square: $4$ equal sides or being drawn large?

Answer: Defining: $4$ equal sides. All squares must have $4$ equal sides; size can vary.

Flashcard 35: What does it mean for an attribute of a shape to be a non-defining attribute?

Answer: It can change and the shape name stays the same. Non-defining attributes like color or size don't affect shape identity.

Flashcard 36: Which option still makes a triangle: $3$ straight sides, or $3$ curved sides?

Answer: $3$ straight sides. Triangles need straight edges, not curved ones.

Flashcard 37: Choose the word that means an attribute that can change and the shape stays the same: defining or non-defining?

Answer: Non-defining. These attributes can vary without changing the shape type.

Flashcard 38: Identify the defining attribute: Is a triangle defined by having $3$ sides or by being red?

Answer: Having $3$ sides is defining. Number of sides determines the shape type.

Flashcard 39: Which attribute can change without changing the shape: number of sides or direction it points?

Flashcard 41: Which option is a non-defining attribute: orientation (turned) or having straight sides?

Answer: Orientation is non-defining. Shapes can face any direction; straight sides define certain shapes.

Flashcard 42: Which attribute is non-defining for a shape: orientation or number of corners?

Answer: Orientation is non-defining. Rotating a shape doesn't change what shape it is.

Flashcard 43: Which option is a defining attribute of a rectangle: $4$ sides or being large?

Answer: $4$ sides. Number of sides defines a shape; size doesn't matter.

Flashcard 44: Which attribute is defining for a rectangle: $4$ right angles or being turned sideways?

Answer: Rectangle. Rectangles have $4$ sides and $4$ corners (right angles).

Flashcard 50: What is a defining attribute of a square in 1st grade geometry?

Answer: A square is closed and has $4$ equal sides and $4$ corners. Equal sides distinguish squares from other rectangles.

Answer: Being red (color). Color can change without changing the shape type.

Flashcard 53: Which attribute can change without changing a triangle: color or being closed?

Answer: Color. A red triangle and blue triangle are both triangles.

Flashcard 54: Which option is a defining attribute of a triangle: $3$ sides or the color blue?

Answer: $3$ sides. Number of sides defines a shape; color doesn't matter.

Flashcard 55: Which statement is correct: A rectangle must have $4$ corners, or a rectangle must be small?

Flashcard 56: Which option stays the same for every square: $4$ equal sides or being tiny?

Answer: $4$ equal sides. All squares must have equal sides; size can vary.

Flashcard 57: What does it mean for an attribute of a shape to be a defining attribute?

Answer: It must be true for the shape to be that shape. Without defining attributes, it wouldn't be that specific shape.

Flashcard 58: Which attribute is non-defining for a shape: color or number of sides?

Answer: Color is non-defining. Shapes keep their identity regardless of color.

Flashcard 59: Which option is a non-defining attribute for any shape: color or number of sides?

Answer: Color is non-defining. Shapes can be any color; side count determines the shape type.
