Skills/Standards	Number, Number Sense and Operations StandardK1 2 3 4 56 7 8 9 10 1. Decompose and recompose whole numbers using factors and exponents (e.g., 32 = 2 x 2 x 2 x 2 x 2 = 2 ^5 ), and explain why “squared” means “second power” and “cubed” means “third power.” 2. Find and use the prime factorization of composite numbers. For example: a. Use the prime factorization to recognize the greatest common factor (GCF). b. Use the prime factorization to recognize the least common multiple (LCM). c. Apply the prime factorization to solve problems and explain solutions. 3. Explain why a number is referred to as being “rational,” and recognize that the expression b a can mean a parts of size 1 b each, a divided by b, or the ratio of a to b. 4. Describe what it means to find a specific percent of a number, using real-life examples. 5. Use models and pictures to relate concepts of ratio, proportion and percent, including percents less than 1 and greater than 100. 6. Use the order of operations, including the use of exponents, decimals and rational numbers, to simplify numerical expressions. 7. Use simple expressions involving integers to represent and solve problems; e.g., if a running back loses 15 yards on the first carry but gains 8 yards on the second carry, what is the net gain/loss? 8. Represent multiplication and division situations involving fractions and decimals with models and visual representations; e.g., show with pattern blocks what it means to take 2 2/3 6. 9. Give examples of how ratios are used to represent comparisons; e.g., part-to-part, part-to-whole, whole-to-part. 10. Recognize that a quotient may be larger than the dividend when the divisor is a fraction; e.g., 6¸ 1/2 = 12. 11. Perform fraction and decimal computations and justify their solutions; e.g., using manipulatives, diagrams, mathematical reasoning. 12. Develop and analyze algorithms for computing with fractions and decimals, and demonstrate fluency in their use. 13. Estimate reasonable solutions to problem situations involving fractions and decimals; e.g., 7/8 + 12/13» 2 and 4.23 x 5.8 »25. 14. Use proportional reasoning, ratios and percents to represent problem situations and determine the reasonableness of solutions. Measurement Standard 2. Use strategies to develop formulas for finding circumference and area of circles, and to determine the area of sectors; e.g., 1/2 circle, 2/3 circle, 1/3 circle, 1/4 circle. 3. Estimate perimeter or circumference and area for circles, triangles and quadrilaterals, and surface area and volume for prisms and cylinders by: a. estimating lengths using string or links, areas using tiles or grid, and volumes using cubes; b. measuring attributes (diameter, side lengths, or heights) and using established formulas for circles, triangles, rectangles, parallelograms and rectangular prisms. N T E N T S TA N D A 4. Determine which measure (perimeter, area, surface area, volume) matches the context for a problem situation; e.g., perimeter is the context for fencing a garden, surface area is the context for painting a room. 5. Understand the difference between perimeter and area, and demonstrate that two shapes may have the same perimeter, but different areas or may have the same area, but different perimeters. 6. Describe what happens to the perimeter and area of a two-dimensional shape when the measurements of the shape are changed; e.g. length of sides are doubled. Geometry and Spatial Sense Standard 1. Classify and describe two-dimensional and three-dimensional geometric figures and objects by using their properties; e.g., interior angle measures, perpendicular/parallel sides, congruent angles/sides. 2. Use standard language to define geometric vocabulary: vertex, face, altitude, diagonal, isosceles, equilateral, acute, obtuse and other vocabulary as appropriate. 3. Use multiple classification criteria to classify triangles; e.g., right scalene triangle. (grade 5) 4. Identify and define relationships between planes; i.e., parallel, perpendicular and intersecting. (grade 5) 5. Predict and describe sizes, positions and orientations of two-dimensional shapes after transformations such as reflections, rotations, translations and dilations. 6. Draw similar figures that model proportional relationships; e.g., model similar figures with a 1 to 2 relationship by sketching two of the same figure, one with corresponding sides twice the length of the other. 7. Build three-dimensional objects with cubes, and sketch the two-dimensional representations of each side; i.e., projection sets. (grade 5) N T E N T S TA N D A R D S Patterns, Functions and Algebra Standard K 1 2 3 4 5 6 7 8 9 10 11 12 1. Represent and analyze patterns, rules and functions, using physical materials, tables and graphs. 2. Use words and symbols to describe numerical and geometric patterns, rules and functions. 3. Recognize and generate equivalent forms of algebraic expressions, and explain how the commutative, associative and distributive properties can be used to generate equivalent forms; e.g., perimeter as 2(l + w) or 2l + 2w. 4. Solve simple linear equations and inequalities using physical models, paper and pencil, tables and graphs. 5. Produce and interpret graphs that represent the relationship between two variables. (grade 7) 6. Evaluate simple expressions by replacing variables with given values, and use formulas in problem-solving situations. 7. Identify and describe situations with constant or varying rates of change, and compare them. Data Analysis and Probability Standard 1. Read, construct and interpret line graphs, circle graphs and histograms. 2. Select, create and use graphical representations that are appropriate for the type of data collected. 3. Compare representations of the same data in different types of graphs, such as a bar graph and circle graph. 7. Design an experiment to test a theoretical probability and explain how the results may vary.
