LTM15 begins with a classroom activity designed to engage learners in a meaningful hands-on investigation through the use of simple physical manipulatives. Wooden cubes are used to investigate the surface area and volume of rectangular prisms in terms of the effect of changing one, two or three dimensions by a specific factor. In the second article in this issue, Jim Metz investigates some interesting links between standardized rectangular paper sizes and the trigonometric ratios for special angles. The third article reports on teacher experiences at the Mathematics Education and Society Conference held in Cape Town in April 2013, while in the fourth article Shakespear Chiphambo discusses a learner's alternative approach to converting fractions into decimal form without a calculator. Tom Penlington then reflects briefly on aspects related to mental mathematics, while in the sixth article Ashley Ah Goo investigates a fascinating relationship between the diameter of a given circle and the dimensions of any inscribed triangle in the circle.
