The lesson begins by labeling the number line with perfect squares that correspond to the integer values, helping students connect whole numbers to their square roots. Students then use these benchmarks to identify which two consecutive integers the given square root lies between. To refine the estimate, the video models how to consider the total number of square roots between each integer and determine which integer the square root is closest to. Visual reasoning and verbal explanations are used throughout to support conceptual understanding. This lesson emphasizes estimation, number sense, and reasoning with irrational numbers and represents what all students should know and be able to do in alignment with Common Core Standard 8.NS.A.2.\n
