Composing and Decomposing Shapes

In this lesson, Instructor Beats teaches how to compose shapes using smaller shapes. The video covers three methods to create a hexagon using trapezoids, rectangles, and triangles. It also includes a WeDo problem to form a pentagon and a uTry problem to create a quadrilateral with right triangles. The lesson emphasizes the importance of manipulating shapes by flipping and rotating them to achieve the desired composition. The video concludes with a recap and encourages viewers to engage with the content by trying the problems themselves.

What is the main objective of the lesson on composing shapes?

• To memorize shape names

• To decompose shapes into smaller parts

• To compose shapes using smaller shapes

• To learn about different types of shapes

Which combination of shapes can be used to compose a hexagon?

• Two rectangles and one square

• Three squares

• Two trapezoids

• One circle and one triangle

How can you compose a hexagon using a trapezoid, a rectangle, and two triangles?

• By arranging them in a circular pattern

• By stacking them vertically

• By placing them randomly

• By flipping and rotating the shapes

What is a five-sided polygon called?

• Triangle

• Quadrilateral

• Pentagon

• Hexagon

What shapes are used to compose a pentagon in the lesson?

• Two squares

• A trapezoid and a triangle

• A rectangle and a hexagon

• Three circles

What is the key attribute of the quadrilateral created using right triangles?

• It is a pentagon

• It has three sides

• It has four right angles

• It is a circle

What happens to the opposite sides of the quadrilateral created in the activity?

• They meet at a point

• They are parallel and never meet

• They form a triangle

• They create a circle

What shape is formed when two right triangles are combined as described in the lesson?

• A hexagon

• A circle

• A rectangle

• A pentagon

What is a right triangle?

• A triangle with two equal angles

• A triangle with no equal sides

• A triangle with all equal sides

• A triangle with a square corner

What is the relationship between decomposing and composing shapes?

• They are unrelated concepts

• Decomposing is the opposite of composing

• Both involve breaking shapes into smaller parts

• Composing is a type of decomposing
