### Power Standards

 Power Standards are the basic concepts that are to be learned in the 7th grade math curriculum. 1. I can +, -, x, and / positive and NEGATIVE rational numbers using integers, fractions and decimals. 2. I can use proportional reasoning to solve problems involving ratios. 3. I can represent proportional relationships with tables, symbols, equations and graphs. 4. I can determine unit rate or slope. 5. I can use properties of algebra to simplify algebraic equations.  (Associative, commutative, and distributive) 6. I can understand the order of operations - PEMDAS. 7. I can understand absolute value (distance from zero on a number line) and its symbol l - 7 l  = 7. 8. I can understand a proportional relationship expressed as y/x = k  or y = kx. 9. I can understand a line has proportional relationship if it passes through the origin with slope as the unit rate. 10. I can solve equations involving variables with positive and NEGATIVE rational numbers. 11. I can calculate the circumference and area of circles using diameter and radius.  Includes area of a sector. 12. I can calculate the volume and surface area of cylinders using the given formulas. 13. I can compare geometric figures for similarity and determine scale factors. 14. I can graph translations and reflections on a coordinate grid and locate new coordinates of a transformation. 15. I can determine mean, median and range from a data display. 16. I can calculate probabilities as fractions, decimals and percents. 17. I can understand the difference between rational (22/7) and irrational (3.14....) numbers. 18. I can locate positive and NEGATIVE rational numbers on a number line and plot pairs on a coordinate grid. 19. I can compare positive and NEGATIVE numbers using <, >, =, <, > 20. I can interpret data in pie charts and histograms. 21. I can use knowledge of real world proportions to determine whether a solution is reasonable. 22. I can solve multi-step problems using proportional relationships.
