Virginia SOL 5.MG.1

5.MG.1 is a Standards of Learning standard. These are the knowledge and skills expectations under it.

• 5.MG.1.a.i

  length (millimeters, centimeters, meters, and kilometers)

• 5.MG.1.a.ii

  mass (grams and kilograms)

• 5.MG.1.a.iii

  liquid volume (milliliters and liters).

• 5.MG.1.b.i

  length (millimeters, centimeters, and meters)

• 5.MG.1.b.ii

  mass (grams and kilograms)

• 5.MG.1.b.iii

  liquid volume (milliliters and liters).

• 5.MG.1.c.i

  length (millimeters, centimeters, meters, and kilometers)

• 5.MG.1.c.ii

  mass (grams and kilograms)

• 5.MG.1.c.iii

  liquid volume (milliliters and liters).

01

What Students Need to Do

Students select metric units that fit an object and situation. They estimate and measure length, mass, and liquid volume with common tools. They use given unit relationships to convert measures and solve context problems.

02

What Mastery Looks Like

A student can explain why a road uses kilometers while a pencil uses centimeters or millimeters. The student estimates reasonably, measures accurately, converts using a supplied equivalence, and labels each answer with the correct unit.

03

Common Misconceptions

Students may choose units by size alone, such as kilograms for a paper clip or milliliters for a bathtub. They often confuse factors of 10, 100, and 1,000 or move the decimal in the wrong direction. Some begin measuring at the ruler's edge instead of the zero mark.

04

How to Assess It

Set out a small filled bottle and a graduated cylinder. Ask students to estimate and measure its volume in milliliters, convert it to liters using 1 liter = 1,000 milliliters, and choose the better label unit.

1. 01

   Set up ruler, balance, and graduated cylinder stations where students estimate and measure a pencil, apple, and cup of water, then record units.

2. 02

   Have students answer the prompt, Choose millimeters or meters for a hallway, then justify when the other unit would make sense.

3. 03

   Play a card match with equivalent measures, such as 3 kilograms and 3,000 grams, using a provided conversion chart to check matches.

4. 04

   Bring grocery labels showing grams, kilograms, milliliters, and liters; students choose three products and rewrite each amount in the paired unit.
