**Numbers & Operations**

Clues to Add How many in all? What is the total? What is the sum? How many altogether? How many

combined?

Clues to Subtract What is the difference? How many more? How many are left? How much longer,

shorter, taller, heavier? How much change?

Denominator the bottom number of a fraction – tells how many parts there are

Difference the answer you get when you subtract

Double a number twice 12+12=24 or 12x2=24

Estimate to find a number that is close to an exact amount by rounding

Equivalent having the same value – equal

Factor a number multiplied

Half to divide into 2 equal groups 14 ÷ 2 = 7

Mixed Number a whole number and a fraction Example 2 3/Numerator the top number of a fraction – tells how many parts are shaded

Product the answer you get when you multiply

Quotient the answer you get when you divide

Round to replace a number with one that tells about how much or how many

Sum the answer you get when you add

Approximately about, estimate

**Measurement**

Area the number of square units needed to cover a space – multiply length x width

Capacity the volume of a container measured in liquid units

Standard – think BIG G

4 quarts= 1 gallon 2 pints = 1 quart 2 cups = 1 pint

1 cup (c) = 8 ounces (oz) 1 tablespoon (tbsp) = 3 teaspoons (tsp)

Metric – 1 liter (L) = 1,000 milliliters (mL)

Century equal to 100 years

Decade equal to 10 years

Degree a unit for measuring angles or temperature

Length (Standard) 1 foot (ft) = 12 inches (in) inch = small paper clip

1 yard (yd) = 3 feet or 36 inches foot = length of notebook paper

1 mile (mi) = 5,280 feet or 1,760 yards yard = baseball bat

Length (Metric) 1 centimeter (cm) = 10 millimeters (mm) centimeter = width of your pinky nail

1 decimeter (dm) = 10 centimeters decimeter = from thumb to pointer finger

1 meter (m) = 100 centimeters meter = your arm span

1 kilometer (km) = 1,000 meters

Mass the measure of the quantity of matter in an object

1 kilogram (kg) = 1,000 grams (g) kilogram = your math book gram = paper clip

Temperature Freezing Point – 32 degrees Fahrenheit – 0 degrees Celsius

Boiling Point - 212 degrees Fahrenheit – 100 degrees Celsius

Body Temp – 98.6 degrees Fahrenheit – 37 degrees Celsius

Room Temp – 68 degrees Fahrenheit – 20 degrees Celsius

Time 1 day = 24 hours 1 hour = 60 minutes 1 minute = 60 seconds 1 week = 7 days

Weight 1 pound (lb) = 16 ounces (oz) 1 ton (T) = 2,000 pounds (lbs)

Year 365 days 52 weeks 12 months

**Geometry**

Angle two rays that have the same endpoint

Acute – an angle whose measure is between 0 and 90 degrees

Right – an angle whose measure is exactly 90 degrees

Obtuse – an angle whose measure is between 90 and 180 degrees

Straight – an angle whose measure is exactly 180 degrees

Complementary angles 2 angles whose measures have a sum of 90 degrees
