### ICT and Math. Good Links from a friends

From - Shamashuddin N Attar

नमस्ते,
ICT मे On line गेम्न का होना बहूत जरूरी है. यह मेरा मत है. games से माऊस ऒर की बोर्ड का स्किल विद्यार्थीयोमे अच्छी तरहसे विकसित होता है. मगर हम जिस गेम्स का उपयोग करेंगे वह शैक्षणिक होना बहूत जरूरी है. शैक्षणिक गेम्स इंटरनेट पर बहूत साते मुफ्त मे उपलब्द है. गणित, सायन्स, भाषा विषयोके इंटरनेट पर उअपल्ब्द गेम्स अध्यालन प्रक्रियांको आनंददायी बनायंगे ऎसा मेरा अनुमान है. मेरे पास आज मिती मे १५० से जादा educational Games उपलब्द है.मैने गणीत विषयोंके बहुत साते स्त्रोत धुंड निकाले है. वह आपको यहापर दे रहा हु.
