Visual riches dominate this issue. Haneet Gandhi talks about Tessellations and the principles they derive from, and also the cultural and historical background in which they are anchored, for example, Islamic art and architecture. Punya Misra and Gaurav Bhatnagar continue their series on the pattern-filled world of Ambigrams and symmetry. The Classroom section has plenty on offer too with a puzzle and articles on assessment, approximations and decimals. In the Tech Space section, Jonaki Ghosh describes how a spreadsheet program like MS Excel can be used to explore the fascinating Fibonacci sequence, and to discover not just the Golden Ratio but also a formula for the Fibonacci numbers. The pullout this time focuses on multiplication.
