Looking for Pythagoras is filled with investigations that develop a fundamentally important relationship connecting geometry to algebra: the Pythagorean Theorem. Students are not merely introduced to a meaningless formula. To encourage deep understanding of what the theorem means, students explore squares created with various lengths, their areas and how these relate to the side lengths of right triangles. Students also explore square roots and strategies for estimating square roots. Irrational numbers are introduced and students are expected to be able to estimate where these occur on a number line.
For an in-depth explanation of unit goals, specific questions to ask your student and examples of core concepts from the unit, go to Looking for Pythagoras.
