Students are given real-world scenarios with problems to solve and questions to answer, and they must come up with a solution (which will necessarily involve square roots, squaring, and pythagorean theorem) and describe the process!
In one problem students are given the area of a yard which is a perfect square. They must find the necessary amount of fencing (will have to take the square root to find the sides) and account for a gate.
In the other problem, students are given the area of a baseball diamond and must find the distance from home to second. This requires taking a square root and then using Pythagorean theorem!
Common Core, real world relevance!
