Rotagram, class set of 20 Posters either by creation of tangram

either by creation of tangram shapes or by directly drawing their designs from the template itself

so that bearings can be measured in a clockwise direction

and efficient way to draw geometric constructions is demonstrated in Chris’s geometric construction video series

Rotagram, class set of 20 Posters either by creation of tangramThe Rotagram is a simple, and highly effective, dynamic protractor design which asks students to measure angle by rotating its movable arm, after locating its vertex over the target angle.
