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

Mathomat is great for:

trigonometry

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. Angle is a difficult and complex topic for many students. As a result students frequently enter secondary school without a full understanding of angle. A common problem for students is that they often develop two different sets of concepts for angle, one static and
