Specific Objective: Grade 6 SS-VI.1.6, pp. D90
- estimates and measures angles
Description: For each angle, estimate the size of the angle in degrees, and enter the number in the "Estimate" Text View.  Check your estimate by colour linking the arc of the angle to the Spreadsheet cell beside "Actual".  Note the size of the angle can be changed by dragging the point at the end of the ray. 
Note:  This activity would fit as a Grade 4 activity if it were modified to require recognition of angle greater than or less than 90 degrees.
