Unit 1

Student Learning Targets

Grade 8

Section ARigid Transformations

1

Moving in the Plane

I can describe how a figure moves and turns to get from one position to another.

2

Naming the Moves

I can identify corresponding points before and after a transformation.
I know the difference between translations, rotations, and reflections.

3

Grid Moves

I can decide which type of transformations will work to move one figure to another.
I can use grids to carry out transformations of figures.

4

Making the Moves

I can use the terms “translation,” “rotation,” and “reflection” to precisely describe transformations.

Section BProperties of Rigid Transformations

7

No Bending or Stretching

I can describe the effects of a rigid transformation on the lengths and angles in a polygon.

8

Rotation Patterns

I can describe how to move one part of a figure to another using a rigid transformation.

9

Moves in Parallel

I can describe the effects of a rigid transformation on a pair of parallel lines.
If I have a pair of vertical angles and know the angle measure of one of them, I can find the angle measure of the other.

10

Composing Figures

I can find missing side lengths or angle measures using properties of rigid transformations.

Section CCongruence

11

What Is the Same?

I can decide whether or not two figures are congruent using rigid transformations.

12

Congruent Polygons

I can decide using rigid transformations whether or not two figures are congruent.

13

Congruence

I can use distances between points to decide if two figures are congruent.

Section DAngles in a Triangle

Section ELet's Put It to Work

Unit 1 Resources

Student Materials

5

Coordinate Moves

I can apply transformations to points on a grid if I know their coordinates.

6

Describing Transformations

I can apply transformations to a polygon on a grid if I know the coordinates of its vertices.

14

Alternate Interior Angles

If I have two parallel lines cut by a transversal, I can identify alternate interior angles and use that to find missing angle measurements.

15

Adding the Angles in a Triangle

I can determine whether three angles could make a triangle using their sum.

16

Parallel Lines and the Angles in a Triangle

I can explain using pictures why the sum of the angles in any triangle is 180 degrees.

17

Rotate and Tessellate

I can repeatedly use rigid transformations to make interesting repeating patterns of figures.
I can use properties of angle sums to reason about how figures will fit together.
