Русский без границ [Russian without Borders] was written for middle and high school students who hear and speak Russian but have not attended Russian school.
It provides sound instruction in literacy with a focus on reading authentic and engaging texts. Two volumes, one for grammar and one for reading, are supported by a workbook.
Russian without Borders was funded by the foundation «Русский мир» (Russian World) and is an international effort, co-written Marina Niznik (Israel), Anna Vinokurova (Germany), Irina Voroncova (Russian Federation), Olga Kagan (U.S.), and Anna Cherp (Israel).
