Divisibility rules for 3, 6, and 9

What you'll learn

• Identify the correct metric unit (millimeter, centimeter, meter, kilometer, gram, kilogram, milliliter, liter) for measuring the length, mass, or volume of common objects with 80% accuracy.
• Explain why a specific metric unit is more appropriate than another for measuring a given object (e.g., 'We use centimeters to measure a crayon because millimeters are too small, and meters are too big.') in at least 3 out of 4 examples.
• Apply knowledge of metric units to estimate the length, mass, or volume of 5 different objects and then measure them using appropriate tools, with estimates within 20% of the actual measurement.
• Solve word problems involving the appropriate use of metric units (length, mass, volume), achieving 70% accuracy on a worksheet with 10 problems.
