(CCSS: 8.EE.A.2, 8.EE.C.7, 8.NS.A.2, 7.RP.A.3, 8.G.B.7, 8.G.B.8) This activity highlights solving equations, using rational approximations to compare the size of irrational numbers, calculating percent change, applying the Pythagorean Theorem, and using square root symbols to represent solutions.
Lisa Tilmon is a educational Infographics - By Lisa Tilmon .It helps students in grades 8 practice the following standards 8.NS.A.2.
1. 8.NS.A.2 : Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., ?^2). For example, by truncating the decimal expansion of ?2 (square root of 2), show that ?2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations..
