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), …Items/Time/Distance can be measured in multiple ways, but retain the same actual value. For example: 1 km = 1,000 m = 100,000 cm (all same length).

conversion - change in the units or form of a measurement, different units, without a change in the size or amount

customary (also called standard) - U.S. measurement system for length in inches, feet, yards,
and miles; capacity in cups, pints, quarts

diagram - a drawing used to describe

gram - a metric unit of mass

inches, foot, centimeter, meter, yards - units used to measure length in the customary or measurement system. There are 12 inches in a foot, and 36 inches in a yard. Centimeters and meters are units used to measure length in the metric measurement system. There are 100 centimeters in a meter.

kilogram - a metric measure of mass

liter - a metric unit of volume, usually to measure liquid

mass/weight - a measure of how much matter is in an object

metric system - measurement system that measures length in millimeters, centimeters, meters, and kilometers; capacity in liters and milliliters; mass in grams and kilograms; and temperature in degrees Celsius

standard (also called customary measurement) - U.S. measurement system of length in inches, feet, yards, and miles; capacity in cups, pints, quarts

weight - the total number of substance present in an object. Customary and metric units can be used to calculate the mass (weight).
Make measurement equivalent statements such as “If one foot is 12 inches, then 3 feet has to be 36 inches because there are 3 groups of 12.”

Create tables to show measurements equivalents with larger units expressed as smaller units within the metric system.

Make tables or charts to show equivalent measurements for pounds and ounces and for hours/minutes/seconds.

Express measurements in a larger unit in terms of a smaller unit by recording measurement equivalents in a two column table.

Use both metric and standard measurement vocabulary.

Apply the area and perimeter formulas for rectangles in real world and mathematical problems.

For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.
area - the size of a surface

perimeter - distance around a figure or object

area of a rectangle - area = length x width

perimeter of a rectangle - perimeter = length + length + width + width
Solve area & perimeter word problems where both length and width are given.

Solve area and perimeter word problems where only one side is given and the total (area or perimeter). Scholars then find the missing side using the total and one side.

Multi-Digit Whole Number -- any set of positive or non-negative integers (0, 1, 2, 3...); numbers that do not contain a fraction or decimal part. A MULTI-DIGIT whole number is a whole number greater than 9.
Identify and explain situations that call for rounding numbers.

Place the number on a number line.

Depending on the place to be rounded, identify the two numbers between which the given number falls. (Ex: to round 382 to the nearest ten, identify that it falls between 380 and 390. Plot those two numbers on the number line. Determine which rounded number is closer to the original number. 382 is 2 away from 380 and 8 away from 390. Therefore 382 rounded to the nearest ten is 380.)

Use other models that make sense for rounding strategies. Explain their reasoning.

Make generalizations that will help them to round without using models.

Use rounding in a variety of situations, including estimation, solving problems, and determining if their answers make sense.

Interpret a multiplication equation as a comparison, e.g., interpret 35 = 5 × 7 as a statement that 35 is 5 times as many as 7 and 7 times as many as 5. Represent verbal statements of multiplicative comparisons as multiplication equations.Multiplication -- a mathematical operation in which a number is added to itself a specific number of times; one factor tells the number of groups or sets, the other factor tells the number of items in a group or set and the result, or product, tells the total number of items (ex: 5 × 3 = 15 5 groups with 3 in each group would give a total of 15)

Multiplication Equation -- a mathematical sentence in which one part is the same or equal to the other part. In this case, it is specific to multiplication. (ex: 5 x 3 = 15)

Comparison -- a multiplication or division situation in which one number is a multiple of the other (ex: Maya has 5 marbles. Alexa has 3 times as many. How many marbles does Alexa have?)

Verbal Statement -- using written words to represent mathematical operations

Multiplicative Comparison
-- see definition for comparison above. In this case, it is specific to multiplication.
Read and interpret multiplicative comparison situations identifying which quantity is being multiplied and which factor is telling how many times.

Write and identify equations and statements for multiplicative comparisons:
* Darlene has seven marbles. Danny has 3 times as many. How many marbles does Danny have? (7 x 3 = 21)
* Danny has 3 times as many marbles as Darlene. (3 x 7 = 21)
* The number of marbles Danny has divided by 3 is the number of marbles Darlene has. (21 / 3 = 7)
* Darlene has 3 times fewer marbles than Danny. (21 / 3 = 7)
