# 4.MD.A.2 Lesson Plans

Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.

## Coherence Map of 4.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 MEASUREMENT PROBLEMS

### What is the standard unit of length?

So our preferred unit of measure for length in the u.s. is miles, and in the rest of the world, it's kilometers. on a smaller scale, along with measuring the length of a pen, we use inches in the u.s. and centimeters in the rest of the world. different u.s. measurements that we use for length are feet and yards.

### What is the conversion factor formula?

This is, conversion factor= (required yield)/(recipe yield) or conversion factor = what you NEED ÷ what you HAVE.

### What is an example of a conversion factor?

"examples of conversion factors For instance, it is viable to transform between two units of mass (e.g., grams to kilos), but you normally cannot convert among units of mass and volume (e.g., grams to gallons). examples of conversion factors include: 1 gallon = 3.78541 liters (extent) 1 pound = 16 oz. (mass)"
