# 3.MD.A.2 Lesson Plans

Measure and estimate liquid volumes and masses of objects using standard units of grams (g), kilograms (kg), and liters (l). (Excludes compound units such as cm^3 and finding the geometric volume of a container.) Add, subtract, multiply, or divide to solve one-step word problems involving masses or volumes that are given in the same units, e.g., by using drawings (such as a beaker with a measurement scale) to represent the problem. (Excludes multiplicative comparison problems (problems involving notions of "times as much.")

## Coherence Map of 3.MD.A.2

The Coherence Map shows the relationships among the Common Core Standards. The Lumos coherence map not only provides graphical representation and convenient navigation within the standards map but also access to thousands of engaging learning resources such as Practice questions, Videos, Books and Infographics related to every standard. It helps educators and students visually explore the learning standards. It's an effective tool to helps students progress through the learning standards. Teachers can use this tool to develop their own pacing charts and lesson plans.

## TOPICS RELATED TO LIQUID VOLUME & MASS

### How do you find the mass of a liquid?

For the reason that density = mass/volume, you can locate the mass of a selected amount of a liquid if you realize its density. you may look up the densities of known liquids in a table. when you have a mystery liquid, you could measure its density with a hydrometer.

### How do you measure mass and volume?

"the mass of water is expressed in grams (g) or kilograms (kg), and the extent is measured in liters (l), cubic centimeters (cm3), or milliliters (ml). density is calculated by the dividing the mass with the aid of the quantity, in order that density is measured as units of mass/quantity, regularly g/ml."

### How does volume affect mass?

"measuring volume For a given mass and volume, how an awful lot bodily space a fabric takes up, of an item or substance, the density stays regular at a given temperature and pressure. ... as with mass, increasing and lowering the amount of cloth additionally increases and decreases the volume of the substance."
