Mathematics, Grade 4: Measurement & Data
4.MD 1. Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), ...
4.MD 6. Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
Mathematics, Grade 4: Geometry
4.G 1. Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.
Mathematics, Grade 7: Geometry
8.G 7. Apply the Pythagorean Theorem to determine unknown side lengths in right triangles in real-world and mathematical problems in two and three dimensions.

Math: Measurement
Instructional programs from Pre-Kindergarten through grade 5 should enable all students to understand measurable attributes of objects and the units, systems and processes of measurement.
- In Pre-Kindergarten through grade 2, all students should recognize the attributes of length, volume, weight, area and time.
- In Pre-Kindergarten through grade 2, all students should select an appropriate unit and tool for the attribute being measured.
- In grades 3-5, all students should understand the need for measuring with standard units and become familiar with standard units in the customary and metric systems.
