In this lesson, student find the square root of small perfect squares and approximate the location of square roots on the number line.

For this lesson, students use rational approximations of irrational numbers to compare the size of irrational numbers. Students place irrational numbers in their approximate locations on a number line.

For this lesson, students apply the method of rational approximation to determine the decimal expansion of a fraction. Students relate the method of rational approximation to the long division algorithm.

For this lesson, students use rational approximation to get the approximate decimal expansion of numbers like the square root of 3 and the square root of 28. Students distinguish between rational and irrational numbers based on decimal expansions.

For this lesson, students apply knowledge of equivalent fractions, long division, and the distributive property to write the decimal expansion of fractions.
