### Description

The anisotropic flow of identified particles is an important observable to test the collective behavior of the dense matter created in heavy-ion collisions. We report on the methods used on the first measurements of elliptic and triangular flow for charged pions, kaons, protons, neutral kaons and $Lambda$ in lead-lead collisions at $sqrt(s_{NN})$=2.76 TeV measured with the ALICE detector at the LHC. Scalar product and Q-Cumulant techniques were used to estimate the flow for charged (neutral) particles in |eta|<0.8 (0.5). The method presented for $K_{s}$ and $Lambda$ can be used for any decaying particle.
