Lesson 2
Definition of Translations and Three Basic Properties
Learner Outcome: I can perform translations of a figure by sliding it along a specific vector.

Facilitator Notes: Lesson is started off with class discussion regarding transformations. Specifically the sliding of objects. Learners will have an understanding of translations before continuing with the video below. Despicable Me introduces the two important parts of a vector. This clip is great for getting learners interested in the topic at hand. See the pdf below for more specifics of introductory discussion.

As you watch the short clip to the right, notice how Vector describes the mathematical term. You may need to watch it a time or two since his humor can be distracting :)

Let's start translating!

To translate along a vector using the sketchpad, watch the short video below.
To translate along a vector using the sketchpad, watch the short video below.
Facilitator Notes: Learners have already been introduced to the sketchpad tool by now. The short screencast below shows a worked example of how to use sketchpad to translate a shape along a vector. The screencast is ideal in this situation because it allows learners to refer back to it when necessary. This tool is useful for learners to practice translating along a vector. The sketchpad takes out the frustration of using a transparency, tracing the images, translating, then having to retrace on their paper.

Now it's your turn! Select the image named Lesson 1-1 by clicking the folder icon in the bottom right corner. Translate shapes Q, S, U, and V by drawing a vector for each, and translating the shapes along the corresponding vector. When you're done, take a screenshot of your final images and submit using the google form at the bottom of the page.

Repeat the process with the image titled Lesson 1-2 in the sketchpad above. To choose this image, click on the folder in the bottom left corner and select the image. Again trace the image and translate along the designated vector. When completed, take a screenshot and submit in the google form below.

Facilitator Notes: The google form is used as a formative assessment to gage how learners are doing with translating shapes along a vector. I am able to view the screenshots to determine what is going well and what needs to be revisited.
