Learn your squares first... 1*1 = 1 2*2 = 4 3*3 = 9 4*4 = 16 now lets say you want the square root of 10 what do we already know? its slightly greater than 3 not by much but slightly so I would write a 3 down. From there I usually just add a decimal or two in my mind and slowly increment it. 3.1...9.61 close.. 3.15... 9.922. closer... basically its a pain if you want to get the exact answer but you can get very close. Just look at the number you want to take the square root of and figure out where it would be in the square list.
