Students will be able to categorize shapes that contain common characteristics. Students will be able to draw and recognize attributes of a quadrilateral, trapezoid, kite, parallelogram, rhombus, rectangle, and square.
- Write the word quadrilateral on the board.
- Ask students to tell you what they think it means.
- Explain to your students that they will learn about the different types of quadrilaterals today.
Explicit Instruction/Teacher modeling(20 minutes)
- Explain that a quadrilateral is a four sided shape. Have students take out a math journal or blank sheet of paper for notes. Instruct students to draw this on the top of their papers, label it, and write 4 sided shape inside it. Model this on the board.
- Explain that there are different types of quadrilaterals, and that today they will focus on three of the different types. Instruct students to draw three arrows underneath the quadrilateral and draw, label, and define those three shapes. Model this for all shapes on the board or chart paper.
- A parallelogram is a four sided shape with equal opposite sides. Point out the equal sides.
- A trapezoid is a four sided shape in which the top and bottom sides are parallel. Point to the parallel sides. Explain that the top and bottom sides are parallel because they will always stay at an equal distance from each other, even if the lines were extended.
- A kite is a four sided shape in which the short sides are equal and the long sides are equal. Explain that if you drew a T inside the kite, you could form four right triangles.
- Instruct learners to draw two arrows under the parallelogram. Explain that there are two types of parallelograms that they will learn about today.
- A rectangle is a four sided shape in which opposite sides are equal. There are four right angles in this shape.
- A rhombus is a four sided shape in which all sides are equal. Mention that the four angles are not always right angles. This shape has four right triangles inside of it if the shape is divided inside.
- Explain that there is one shape that falls under the categories of rectangle and rhombus. Explain that a square has four right angles and four equal sides.
- Tell students that a shape under an arrow shares all the qualities of the shape above it. For example, a square is a rectangle, parallelogram, and a quadrilateral. A rectangle is a parallelogram and quadrilateral and a parallelogram is a quadrilateral.
- Point to the shapes when you explain the relationship and categories they fit under to demonstrate how to follow the chart.
Guided Practice(10 minutes)
- Create student partnerships and distribute a copy of the Naming Quadrilaterals worksheet to each student.
- Instruct students to complete the worksheet together, discussing how they know the name for each shape. Remind them to utilize their notes to assist them in this task.
- Call on nonvolunteers to share their answers and reasoning.
Independent working time(15 minutes)
- Hand each student seven index cards.
- Instruct students to write the name and picture of each shape on the front of the card and the characteristics on the back of the card.
- Direct students to use the chart to help them.
- Ask students to display their cards in a chart format.
- Walk around to see if students have done it correctly.
- Instruct students to create a picture using the shapes they've learned about. Instruct them to label each shape on their picture.
- Explain to students that the quadrilateral is like a great-grandmother, and the parallelogram, trapezoid, and kite are the grandparents. Explain that rectangle and rhombus are the parallelogram's kids. Help your students understand the relationships between different quadrilaterals by comparing them to real life situations.
- Provide a word bank of the shapes on the board for spelling purposes.
- Conduct a short quiz on shapes. Example questions include: * What are the two shapes with four right angles? Name two shapes that are parallelograms. What is the biggest category of a four sided shape? Which shape has four sides that are the same but isn't a square? Which shape has one pair of parallel sides?
- Collect papers to grade.
Review and closing(5 minutes)
- Go around the class, and ask your students which shape they liked learning about the most.
- Invite them to use their arms and hands to demonstrate the shapes.
