Your Date with Slate - Flare Tangram Activity
View email in your browser
Hi <<First Name>>,
 
Get ready to run a Flare Tangram activity! We hope by now that you've explored the functions within Flare and tested out the different features explained in the last two dates. If you missed them, please click here. Today we'll run through Tangram Activity 8, called Calculating Angles.

Activity 8 can be found in the teacher's notes. To get started with the activity, open Slate and navigate to the Flare Tangram.

 
The purpose of this activity is to ask students to determine the interior angle of each tangram piece without measuring them with a protractor. Remind them that there are 360 degrees in one full turn around a point.
Use the fill icon and the shades palette to color the Tangram square as shown on the left. Then select Setup > Break Apart to scatter the pieces.

Invite some students to demonstrate how they determined the size of the angle by using the hand tool to move and rotate the pieces.
Overlay the angles that are 90 degrees to check that they are all congruent. Arrange four of the 90-degree angles around a point. Say: "If there are 360 degrees in one full turn around a point, and that point has been split into four equal amounts, then each angle around the point is 90 degrees (360/4 = 90). Therefore, each angle that is congruent with these angles is 90 degrees."
There are other solutions to this activity, which you can find on the activity page.

We hope you have enjoyed getting to know Flare in this series. We will demonstrate some other activities in upcoming Date with Slate emails!
