Mathomat V7 geometry template in storage wallet, supplied with a 72 page illustrated student manual. The student manual is written and illustrated by Juliet Snape. There are a series of contextualised activities that explore real world connections to a series of important mathematical ideas. Students are encouraged to engage deeply, and to build confidence, with classroom mathematics.
Juliet's Explorer manual investigations can also be accessed in the Mathomat Activity Centre for use with all Mathomat V7 template versions. The activities are further extended with instructional videos, solutions and extension ideas in MAC.
The Mathomat V7 geometry template.
The Mathomat V7 template is a large format template, with a great selection of shapes arranged in a user-friendly hierarchical pattern around its central protractor. The Mathomat V7 template has many great new features, including:
Tisdell’s geometry tool
Professor Tisdell’s new geometry tool (TGT) can create all the geometric constructions in school curricula by using a single radius with a defined centre for rapid and accurate template placement. This accurate, safe, and efficient way to draw geometric constructions is demonstrated in Chris’s geometric construction video series, in the paper Beyond the Compass by Chris and David Bee Olmedo. The TGT is a hands-on way of constructing geometry, consistent with our design philosophy. 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.
Larger shapes to draw with
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.
New geometry tools in Mathomat V3
The Mathomat V7 includes three new tools that expand its creative potential:
The tangram tool. Can be used to construct the three different sized triangles needed to complete the ancient Chinese tangram puzzle. These are complemented by other matching tangram shapes in the Mathomat V3.
The regular polygon expansion scale. Will construct extra-large (50mm sided) regular polygons from similar shapes in Mathomat.
The arc builder scale. Will create extra-large arcs and circles.
The usual great range of Mathomat shapes and scales
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.
