• Place Value with Decimals: Students extend their understanding of place value to include tenths and hundredths. They learn to read, write, and compare decimals to the hundredths place.
• Relating Fractions and Decimals: Students learn to convert between fractions with denominators of 10 or 100 and their decimal equivalents. They use visual models to represent the relationship between fractions and decimals.
• Comparing Decimals: Students learn to compare decimals to the hundredths place using the symbols >, <, and =.

4. Geometry

• Lines, Angles, and Shapes: Fourth graders learn to identify and classify different types of lines (parallel, perpendicular, intersecting) and angles (acute, obtuse, right). They use this knowledge to classify two-dimensional shapes based on their attributes.
• Geometric Shapes: Students learn to identify and draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. They also classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size.
• Symmetry: Students learn about lines of symmetry and identify shapes that have line symmetry. They learn to draw lines of symmetry on symmetrical shapes.
• Area and Perimeter: Students build upon their previous understanding of area and perimeter to find the area and perimeter of more complex shapes, including rectangles and composite figures. They learn to apply the formulas for area and perimeter in problem-solving situations.
• Angle Measurement: Students learn to measure angles in whole-number degrees using a protractor. They sketch angles of specified measure.

5. Measurement

• Units of Measurement: Fourth graders work with different units of measurement, including units of length (inches, feet, yards, miles, centimeters, meters, kilometers), weight (ounces, pounds, grams, kilograms), volume (cups, pints, quarts, gallons, liters), and time (seconds, minutes, hours, days, weeks, months, years).
• Conversion of Units: Students learn to convert between different units of measurement within the same system (e.g., converting feet to inches, kilograms to grams). They use these conversions to solve real-world problems.
• Time: Students deepen their understanding of time, including telling time to the nearest minute and solving problems involving elapsed time.
• Area and Perimeter (Revisited): As mentioned in geometry, students apply measurement concepts to find the area and perimeter of various shapes.

6. Data Analysis
