Section A: Practice Problems Flat and Solid Shapes

Section Summary


We learned about solid shapes.

Geoblock. Cone.
Solid shape. cube.

We learned about flat shapes.

Closed shape. 4 straight sides, different lengths. 4 points.

We described and named shapes.

This shape is a triangle because it has 3 straight sides and 3 corners.

Closed shape. 3 straight sides. 3 corners, pointy.

These shapes are all rectangles because they have 4 straight sides and 4 square corners.

A collection of rectangles.

We built larger shapes from smaller shapes.

Problem 1 (Pre-Unit)

Name each shape.

  1. Closed shape. 3 straight sides. 3 corners, pointy.
  2. Shape.
  3. Closed shape. 4 straight sides of equal length. 4 square corners.

Problem 2 (Pre-Unit)

Color in all of the triangles.
Cross out all of the rectangles.

A collection of flat shapes.

Problem 3 (Pre-Unit)

Cross out all of the circles.

A collection of flat shapes.

Problem 4 (Lesson 1)

Jada felt a shape in a bag.
She felt a point and a curve.
Circle the shape that could be in the bag.

  1. Solid shape. Sphere.
  2. Solid shape. Cube.
  3. Solid shape. Cylinder.
  4. Solid shape. Cone.

Problem 5 (Lesson 2)

This is the tallest skyscraper in the world.

Use the blocks to build a shape that looks like the skyscraper.

Skyscraper. Burj Khalifa.

Problem 6 (Lesson 3)

Here is how Diego sorted some shape cards.

Chart, 2 groups. Circles of different sizes. Closed shapes with 3, 4, or 6 straight sides.

Draw each shape where it belongs on Diego’s chart.


Problem 7 (Lesson 4)

Here is a shape.

  1. Draw the shape on dot paper.

    Dot paper.
  2. Describe the shape.

Problem 8 (Lesson 5)

Is this shape a triangle? Why or why not?

Dot paper drawing. Shape with 4 sides.

Problem 9 (Lesson 6)

  1. Draw 2 different rectangles and 2 different squares.

    Dot paper.
  2. How are the shapes the same? How are they different?

Problem 10 (Lesson 7)

Pattern blocks puzzle.
  1. Use pattern blocks to fill the outline in different ways.

  2. Write the number of pattern blocks you used for each way.

Problem 11 (Exploration)

  1. Choose an object in the classroom or outside and use the geoblocks to build the object.

  2. Share your object with a partner and try to guess what your partner built.

Problem 12 (Exploration)

Pattern block puzzle.
  1. What is the smallest number of pattern blocks you can use to fill in the puzzle?

  2. What is the largest number of pattern blocks you can use to fill in the puzzle?

  3. Can you fill in the puzzle using exactly 12 pattern blocks?
