Understanding Shape Attributes
What do we call a shape with 4 sides?
What is a quadrilateral?
What shape has all sides equal and opposite angles equal?
What is a rhombus?
If you divide a square into 4 equal parts, what fraction of the square is each part?
What is 1/4?
What is an angle smaller than 90 degrees called?
What is an acute angle?
What is a net?
What is a flat shape that can be folded to form a three-dimensional shape?
Name two shapes that are considered quadrilaterals.
What are a rectangle and a rhombus?
Is a square a type of rectangle? Why?
Yes, because it has four right angles and opposite sides equal.
Can a circle be divided into equal parts? How many parts can it be divided into?
Yes, it can be divided into any number of equal parts.
What is an angle larger than 90 degrees called?
What is an obtuse angle?
Identify this net: it has two rectangles and two triangles.
What is a triangular prism?
How can a square be classified?
What is a rhombus and a rectangle?
What is a characteristic of a rectangle?
What are four right angles?
How would you divide a rectangle into 6 equal parts?
(Student describes dividing into smaller rectangles or squares.)
Sketch an acute angle.
(Student sketches an angle less than 90 degrees.)
What three-dimensional shape is created from a rectangular net with two rectangles and four squares?
What is a right rectangular prism?
Draw a quadrilateral that is not a square, rectangle, or rhombus.
(Student draws a shape like a trapezoid.)
Can a shape be a quadrilateral but not a rectangle, square, or rhombus? Give an example.
Yes, an example is a trapezoid.
What do we call shapes that are divided into equal areas?
What are partitions or fractions?
How can you use a right angle to find other angles?
By comparing other angles to the 90-degree angle.
How can you tell what three-dimensional shape a net will form?
By counting the sides and shapes in the net.
What attribute do all quadrilaterals share?
What is having four sides?
How many sides does a quadrilateral have?
What is four sides?
Why do equal parts of an identical whole not need to be the same shape?
Because they can have different dimensions but still cover the same area.
Give an example of where you might see acute and obtuse angles in real life.
(Student provides examples, such as in buildings or furniture.)
You might see an acute angle formed by the blades of a pair of scissors when they are open, or the corner of a book. An obtuse angle could be seen when a door is opened more than halfway, or the angle formed between the hour and minute hand of a clock at 4 o'clock.
Draw a net for a pyramid.
(Student draws a net consisting of a square base and four triangles.)
