Measurement and Data
1 Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12], (2, 24], (3, 36], ...

Match everyday containers to the best U.S. capacity unit (cup, pint, quart, gallon, or fluid ounce). Use pictures to judge whether something holds a little, some, or a lot of liquid. Get familiar with what common amounts like 1 cup, 1 pint, 1 quart, and 1 gallon look like in real life.
4md1
Choose the best US capacity unit (cup, pint, quart, gallon, or fluid ounce) to match a real-life situation. Tell when a container or amount is small, medium, or large and pick a unit that makes sense.
4md1
Choose whether inches, feet, yards, or miles makes the most sense for a given distance. Use what you know about common objects and places to make a reasonable estimate of a length. Explain why one unit is more appropriate than another for measuring a specific distance.
4md1
Get better at making a reasonable guess for how long an object is without measuring it. Choose the best length from a few options by comparing what you see to familiar sizes (like an inch, foot, or yard). Decide which unit makes sense for an object’s length (inches, feet, or yards). Use benchmark lengths to tell when an estimate is too short or too long.
4md1
Practice balancing measurement equations by figuring out the missing amount that makes both sides equal.
4md1
Convert between larger and smaller units of length, weight, and liquid volume. Use a conversion table to find the matching value in a different unit. Multiply or divide by a conversion factor to fill in missing measurements.
4md1
Convert a measurement written in mixed units (like feet and inches) into just the smaller unit. Use the correct conversion facts between inches, feet, yards, and miles.
4md1
Convert a mixed metric length (like meters and centimeters) into just the smaller unit. Use the metric relationships (10, 100, 1,000) to move between kilometers, meters, centimeters, and millimeters. Combine the converted parts correctly to write one total measurement in a single unit.
4md1
Choose the best metric unit to describe how long something is. Tell when millimeters, centimeters, meters, or kilometers make the most sense for an item. Compare a few unit choices and pick the one that matches a reasonable real-world size. Read a short description of an object and decide which metric measurement fits.
4md1
Practice reading a centimeter ruler to find the length of a bar, including half-centimeter measurements Subtract the starting point from the ending point when the bar doesn't begin at zero Measure to the nearest half centimeter using the smaller tick marks on the ruler
4md1
Practice making a reasonable guess about how long something is using metric units. Learn to choose the best unit for a length (millimeters, centimeters, meters, or kilometers). Compare a few possible lengths and pick the one that makes the most sense for the object shown. Use what you know about common objects to judge about how long something is without measuring.
4md1
Practice writing the correct abbreviations for common U.S. customary units like inches, feet, yards, and miles. Practice writing the correct abbreviations for common weight and capacity units like ounces, pounds, cups, pints, quarts, and gallons. Practice writing the correct abbreviations for metric units like millimeters, centimeters, meters, kilometers, milliliters, and liters. Learn to match a unit name to its standard abbreviation without mixing up similar-looking abbreviations (like m vs mi or oz vs lb).
4md1
Practice reading common measurement abbreviations and writing the full unit name. Learn the correct spelling of standard and metric measurement units. Recognize similar-looking abbreviations and match each one to the right unit.
4md1
Convert a number of days into weeks by grouping days into sets of 7. Convert a number of weeks into days by counting 7 days for each week.
4md1
Convert hours into days by using the fact that 1 day equals 24 hours. Convert days into hours by multiplying by 24.
4md1
Convert between pounds and ounces. Fill in missing weights in a chart using the conversion facts.
4md1
Estimate how much common objects weigh using tons, pounds and ounces. Choose the most reasonable weight from a few options by comparing sizes and what you already know. Tell the difference between light items measured in ounces and heavier items measured in pounds.
4md1
Practice converting pounds to ounces using the fact that 1 pound equals 16 ounces. Practice converting ounces to pounds by dividing by 16. Work with multiplication and division facts to switch between two common US weight units.
4md1
Practice converting mixed weight measurements into a single smaller unit (like tons and pounds into just pounds) Use the conversion facts that 1 ton = 2,000 pounds and 1 pound = 16 ounces Multiply the larger unit by the conversion factor and then add the leftover smaller units
4md1
Practice converting between grams and kilograms. Compare two weights even when they are written in different units. Use >, <, and = to show which weight is greater, less, or equal.
4md1
Convert between metric weight units like grams and kilograms. Fill in missing values in a weight chart by using what you know about metric conversions. Answer questions that require switching units before you can solve the problem.
4md1
Convert between seconds and minutes Convert between minutes and hours Convert hours to days Read a word problem and decide which way the conversion goes
4md1
Decide which of two lengths is longer or shorter when the units differ. Convert to a common unit before comparing. Recognize that the larger number is not always the longer length.
4md1
Decide which of two lengths is longer or shorter when the units differ. Convert to a common unit before comparing. Recognize that the larger number is not always the longer length.
4md1
Choose the customary unit that best fits what is being measured. Tell length, weight and liquid volume apart from the situation alone. Use the largest unit that still gives a number of at least 1.
4md1
Choose the metric unit that best fits what is being measured. Tell length, mass and liquid volume apart from the situation alone. Use the largest unit that still gives a number of at least 1.
4md1
Judge whether a stated measurement is sensible for the situation. Recognize a measurement that uses the wrong unit. Recognize a measurement that uses the right unit but the wrong amount.
4md1
Choose a reasonable temperature for an everyday situation. Read a temperature against the scale it is written in. Compare Fahrenheit and Celsius values for the same situation.
4md1
Choose a reasonable weight for a familiar object. Tell ounces from pounds from tons by size. Use a known object as a benchmark for another.
4md1
Choose a reasonable capacity for a familiar container. Tell fluid ounces from cups from gallons by size. Use a known container as a benchmark for another.
4md1
Convert mixed U.S. volume measurements into a single smaller unit. Use the relationships between gallons, quarts, pints, cups, and fluid ounces to rewrite amounts correctly.
