4. Common Core GPS
MCC8. G. 3: Describe the effect of dilations,
translations, rotations, and reflections on twodimensional figures using coordinates.
MCC8. G. 4: Understand that a two-dimensional
figure is similar to another if the second can be
obtained from the first by a sequence of
rotations, reflections, translations, and dilations;
given two similar two-dimensional figures,
describe a sequence that exhibits the similarity
between them.
5. Language of the Standards
Let’s make a list of the important terms we have
talked about in unit 1.
7. Work Session: Listening for
Understanding
Transformations will be placed on cards of equal size. You
will be paired with a partner. You will alternate turns
explaining to your partner how to re-create a figure
and its transformation on a card. You will need to use
key words such as rotation, reflection, translation,
dilation, scale factor, coordinates, vertices, and
corresponding sides/angles. At no time may the card
be shown to your partner who is creating the
transformation on his/her own coordinate plane. As a
final piece of information, the student drawing the
transformations must write on his/her paper the
transformations that took place to give him/her the
transformed figure.
