NC.4.G.1 Draw and identify points, lines, line segments, rays, angles, and perpendicular and parallel lines.
NC.4.G.2 Classify quadrilaterals and triangles based on angle measure, side lengths, and the presence or absence of parallel or perpendicular lines.
NC.4.G.3 Recognize symmetry in a two-dimensional figure, and identify and draw lines of symmetry.
NC.4.MD.6 Develop an understanding of angles and angle measurement.
Understand angles as geometric shapes that are formed wherever two rays share a common endpoint, and are measured in degrees.
Measure and sketch angles in whole-number degrees using a protractor.
Solve addition and subtraction problems to find unknown angles on a diagram in real-world and mathematical problems.
NC.4.MD.1 Know the relative sizes of measurement units. Solve problems involving metric measurement.
Measure to solve problems involving metric units: centimeter, meter, gram, kilogram, liter, milliliter.
Add, subtract, multiply, and divide to solve one-step word problems involving whole-number measurements of length, mass, and capacity that are given in metric units.
NC.4.MD.2 Use multiplicative reasoning to convert metric measurements from a larger unit to a smaller unit using place value understanding, two-column tables, and length models.
NC.4.MD.8 Solve word problems involving addition and subtraction of time intervals that cross the hour.
NC.4.NF.6 Use decimal notation to represent fractions.
Use equivalent fractions to add two fractions with denominators of 10 or 100.
Represent tenths and hundredths with models, making connections between fractions and decimals.
NC.4.NF.7 Compare two decimals to hundredths by reasoning about their size using area and length models, and recording the results of comparisons with the symbols >, =, or <. Recognize that comparisons are valid only when the two decimals refer to the same whole.
