Use Prime Factorization - Use the prime factorization of two whole numbers to determine the greatest common factor and the least common multiple.

Fractions and Decimals - Use visual models, benchmarks, and equivalent forms to add and subtract commonly used fractions and decimals.

Factoring - Use divisibility rules to factor numbers.

Estimation - Make reasonable estimates of fraction and decimal sums and differences.

Mixed Numbers - Add and subtract mixed numbers.

Decimal Point - Understand the placement of the decimal point in calculations of multiplication and long division, including the placement in the estimation of the answer.

Division by Zero - Understand that division by zero is undefined.

Negative Numbers - Explore numbers less than 0 by extending the number line through familiar applications (e.g., temperatures below zero, owing money, measuring elevation below sea level).

Exponential Notation - Use exponential notation to represent repeated multiplication of whole numbers.

Triangle Area - Develop the formula for the area of a triangle as it relates to the area of a parallelogram/rectangle.

Polygon Area - Find the area of a convex polygon by decomposing it into triangles/rectangles.

Prisms - Build, draw, and work with prisms by means of orthogonal views, projective views, and nets.

Platonic Solids - Describe and identify the five regular (Platonic) solids and their properties with respect to faces, shapes of faces, edges, and vertices.

Filling Space - Quantify total volume as filling space with same-sized units of volume without gaps or overlap.

Surface Area - Decompose prisms to calculate surface area and volume.

Appropriate Units - Understand, select and use units of appropriate size and type to measure angles, lengths/distances, area, surface area and volume.

Line Segments - Identify characteristics of the set of points that define vertical and horizontal line segments.

Significant Digits - Correctly interpret significant digits in the accuracy of measurements and associated calculations.

Estimates - Recognize that measurements are never exact.

Approximation - Understand the usefulness of approximations.

Correct Tools - Develop strategies for choosing correct tools of measurement.

Weight Temperature - Recognize and use measures of weight and temperature.

## Mathematical Process

Geometric Prop- Make and testxer conjectures about geometric properties and develop logical arguments to justify conclusions.Estimation- Make reasonable estimates of fraction and decimal sums or differences using models.Rounding- Explore different methods of estimation including rounding and truncating.Remainders- Explore problems in different contexts to interpret the meaning of remainders as discrete values or not.Solve Problems- Solve problems in more than one way and explain why one process may be more effective than another.State Answers- Communicate answers in correct verbal and numerical form; including use of mixed numbers or fractions and use of units.Verbal- Organize and consolidate verbal statements involving fractions and mixed numbers into diagrams, symbols, and numerical expressions.Patterns- Use patterns, models, and relationships as contexts for writing inequalities and simple equations.Other Media- Use age-appropriate books, stories, and videos to convey ideas of mathematics.Addition Using Estimation (AAA Math)
