Timu (kutoka Kiingereza "team") ni kundi la watu wanaofanya kazi ili kufikia lengo la pamoja. Wanachama wa timu wanahitaji kujifunza jinsi ya kusaidiana, kusaidia wanachama wengine wa timu, kutambua uwezo wao kwa kila mmoja, na kujenga mazingira ambayo yanaruhusu kila mtu awe anajua umuhimu wake, hata kama timu ndogo za sekondari ni za muda mfupi.
