If I wanted to estimate the √99, the first step would be to find the two squares that 99 lies on the numberline. I could then think about the number 99 and how close it is to the smaller perfect square and the larger perfect square. That would tell me how far above or below the of the two perfect squares 99 lies on the numberline. I could then take the root of the perfect squares to see how I would estimate the square root of 99. The √99 is almost .
