New Mathomat template versions 

New versions of the Mathomat template will be released in term one, 2021. The first called Mathomat V3 will complement the existing and very popular Mathomat V2 design, The larger polygons in the Mathomat V2 become even larger in the Mathomat V3, allowing for greater creativity with 2D and 3D pattern drawing, including construction of larger nets for polyhedra. Additional Mathomat versions that offer further creative options for pattern design will be released soon after the V3 template becomes available later this year. Of course, the current Mathomat V2 template will continue as a core part of our product range.
A senior school version of the very popular R300T Mathomat template for pencil cases, called R300TS will be released for term 1, 2021.

New investigations for the illustrated Mathomat V2 template Explorer Manual

The concept of angle is surprisingly complex, with a rich history. In these new investigations  we make  the dry, abstract, diagrams that are normally used to represent angle interesting by placing them into meaningful, engaging, contexts.

We begin our new investigations by sending the Mathomat kids back in time to conduct imaginary interviews with mathematicians of the past. The Mathomat kids are briefed to ask three important questions about angle*:

  • We ask Euclid, “can angles contain curves?”, as he is working on definitions 8 and 9 of the Elements.*
  • We then find Proculus, reflecting on the 900 years of intellectual achievements in the classical age. We ask him the question, “what exactly is being measured when referring to the size of angles?”*
  • Renaissance breakthrough, angles can be greater than 180 degrees! *

Their teacher then asks the Mathomat kids to search for examples of angles in the wild. The Mathomat kids are doing remote learning at the time so they do this by exploring the rooms in their own houses, and then in their gardens. They use the cameras in their mobile devices to take photographs, and their Mathomat templates to make drawings, of as many interesting angle examples that they can find.

Coming together with her students again, the teacher asks them to do a presentation of the angles they have found. Their teacher challenges the Mathomat kids to re-organise their angle collections into the same groups they discussed with Proculus and which she has found as separate definitions in their text books.

 

Lesson debrief

The Mathomat kids discover that there are aspects of an angle drawing which can be misleading when measuring its magnitude.

The Mathomat kids also realise that there is one particular way of representing angles in their text book that can be used to represent all of the angle situations they found in the wild, and which they discussed in their imaginary interviews with mathematicians of the past.
