Measurement

Length, Capacity, Weight, & Temperature

2nd Grade Standards

Apply measurement skills to measure the attributes of an object (length, capacity, weight).

Read temperatures on a thermometer using Fahrenheit and Celsius.

Demonstrate unit conversions 1 foot = 12 inches 1 quart = 4 cups 1 pound = 16 ounces 1 hour = 60 minutes 1 day = 24 hours 1 week = 7 days, and

1 year = 12 months.

3rd Grade StandardsApply measurement skills to measure length, weight, and capacity using US Customary units.

Convert units of length, weight, and capacity inches or feet to yards ounces to pounds cups to pints pints to quarts

quarts to gallons

Measure and calculate perimeter of 2-dimensional figures.

How We Measure

Measuring Systems

Length: the longest dimension of an object. We measure length when we want to know how long something is.

Distance: is a numerical description of how far apart objects are. We measure distance when we want to know how far apart things are from on another.

Capacity: is the ability to hold a fluid. We measure

capacity when want to know how much fluid is in or is needed

for something.

Volume: is the amount of space a substance (solid or liquid) occupies or contains in a 3-D object. We measure volume when we want to know how much a solid or liquid can fill a 3-D area.
