Mathomat V7 Geometry Template- with Exploring hidden angles, a Mathomat adventure, by John Lawton.
Available Term 4, 2024
A Mathomat V7 geometry template in storage wallet, supplied with a 48 page student book, written by John Lawton and illustrated by Juliet Snape. Drawing from John's research work on the teaching of angle in geometry. This book celebrates, and encourages, student visualisation as an important creative process in mathematics. Students learn to understand the geometric structure of their world by discovering hidden angles. They develop deep, flexible, geometric knowledge through understanding the concept of angle. This builds confidence with classroom mathematics, project work and real world problem solving.

The Mathomat V7 geometry template
The Mathomat V7 template is a large format template, it is the same shape as the more compact Mathomat V2 but is 22% larger in area. It has the same great selection of shapes arranged in a user-friendly hierarchical pattern around its central protractor that you would expect in a Mathomat. The larger Mathomat V7 template includes many great new features, including:
Professor Tisdell’s new geometry tool (TGT) is now part of the Mathomat V7 template. This new feature in Mathomat can create all the geometric constructions in the school curricula by using a single radius with a defined centre for rapid and accurate placement. This accurate, safe, and efficient way to draw geometric constructions is demonstrated in Chris’s geometric construction video series, and in the paper Beyond the Compass by Chris and David Bee Olmedo. The TGT is also a hands-on way of constructing geometry, consistent with our design philosophy of fostering learners as builders and inventors. The physical nature of the TGT keeps students in contact with geometry in a physical sense while encouraging abstract thinking in terms of the points, lines, and arcs inherent in the tool and its use.
The TGT is positioned close to the straight edge on the left side of the Mathomat template for maximum coordination between both while drawing. As pointed out in David and Chris’s paper, the integration of the straight edge and the TGT in Mathomat reduces the complexity and time involved in creating geometric constructions in comparison with the use of a compass and straight edge.
In the Mathomat V7 template the side length of the larger group of polygons has been increased to 20mm (from 15mm in the Mathomat V2 template). This allows for drawing useful sized nets to construct polyhedra and other 3-D shapes and for the drawing of larger 2-D patterns such as tessellation designs. It is easier for students to see the geometric structure of these larger shapes.
A useful feature of the Mathomat V7 template is that its larger regular polygons now include a full set of pattern block shapes, which can be used in 2-D drawings to explore the many geometric designs that both primary and secondary schools have developed for these widely used concrete materials.
The Mathomat V7 includes three new tools that expand its creative potential:
The Mathomat V7 template has all the great range of shape stencils such as useful graduated circles, ellipses, regular polygons, quadrilaterals, and graphing curves that you would expect. Mathomat V7 also has the same rich collection of number lines as before, such as a linear radian scale, millimetre, and centimetre scale and 1:20,000 street directory scale.as well as isometric and parallel lines for technical drawing.
