The rubric Focus presents Zahra Nugraheni with her ideas on how mathematics education can contribute to the realization of SDGs, and Allan White on how atomic power can steam up the classroom. In Reader’s Voice, we present Herizal who sheds light on the importance of mathematics teachers’ proficiency on pure mathematics knowledge. In Math Around Us, Giani opens our eyes on the mathematics of online shopping, and Tevan Adi Satria discovers that the globes are incorrect. Chang Chen Yow and Negara Mangkubumi Kastolani share interesting new tools on teaching mathematics – fraction bars and MathCityMap – in Development and Innovation. While in Best Practice, we have Isna Sofiatun with DataWise and Ummu Fauziyyatun with STEM glider challenge. Don’t forget to visit our Hall of Fame, where teacher Dian Septi Chusna showcase the statistical literacy in her classroom.
