Lesson 6 All Kinds of Attributes

    • Let’s use what we know about attributes of figures to create drawings.

Warm-up How Many Do You See: Dot after Dot

How many do you see? How do you see them?

7 columns of dots.

Activity 1 You’re Gonna Draw It: It’s Symmetric

Problem 1

Here is a pair of parallel segments that have the same length.
Add one or more segments to create a figure with only 1 line of symmetry.

2 parallel line segments on grid. Both vertical, with length of 4 units.

Problem 2

Here are two more pairs of parallel segments. Add more segments to make:

  1. a figure with 2 lines of symmetry

    2 parallel line segments on grid. Both vertical, with length of 4 units.

  2. a figure with no lines of symmetry

    2 parallel line segments on grid. Both vertical, with length of 4 units.

Problem 3

If you have time… Here are some other pairs of parallel lines. Add more segments to create a figure with 1 line of symmetry.

2 parallel line segments on grid. Both vertical. Left segment, 2 units. Right segment, 4 units.
2 parallel line segments on grid. Both vertical. Both segments, 4 units. Right segment 2 units higher than left segment.

Activity 2 Hidden Shapes

Here is a field of dots.

Can you connect the dots to create each of the following shapes? If so, draw the shapes. If not, be prepared to explain your reasoning.

  1. A triangle with only one line of symmetry

  2. A quadrilateral with only one line of symmetry

  3. A quadrilateral with two pairs of parallel sides

  4. A quadrilateral with one pair of perpendicular sides

  5. A rectangle

  6. A six-sided shape with only one line of symmetry
