4.1.2: Use models to connect and compare equivalent fractions and decimals.
4.1.3: Determine decimal equivalents or approximations of common fractions.
4.1.4: Compare and order fractions and decimals.
4.1.5: Estimate decimal or fractional amounts in problem solving.
4.2.2: Apply understanding of models for multiplication (e.g., equal-sized groups, arrays, area models, equal intervals on the number line), place value, and properties of operations (commutative, associative, and distributive).
4.2.3: Select and use appropriate estimation strategies for multiplication (e.g., use benchmarks, overestimate, underestimate, round) to calculate mentally based on the problem situation when computing with whole numbers.
4.3.1: Recognize area as an attribute of two-dimensional regions.
4.3.2: Determine area by finding the total number of same-sized units of area that cover a shape without gaps or overlaps.
4.3.3: Recognize a square that is one unit on a side as the standard unit for measuring area.
4.3.4: Determine the appropriate units, strategies, and tools to solving problems that involve estimating or measuring area.
4.3.6: Find the areas of complex shapes that can be subdivided into rectangles.
4.3.7: Solve problems involving perimeters and areas of rectangles and squares.
4.3.8: Recognize that rectangles with the same area can have different perimeters and that rectangles with the same perimeter can have different areas.
