About: with reference to rounding and estimation, an answer that is not precise.
Addend: the numbers that are added together in an addition equation.
Capacity: the amount of liquid that a particular container can hold.
Continuous: with reference to time as a continuous measurement.
Endpoint: used with rounding on the number line; the numbers that mark the beginning and end of a given interval.
Gram (g): a unit of measure for weight.
Interval: time passed or a segment on the number line.
Halfway: with reference to a number line, the midpoint between two number.
Kilogram (kg): unit of measure for mass, 1,000 grams = 1 kilogram.
Liquid volume: the space a liquid takes up.
Approximate (≈): a symbol used to show that an answer is approximate.
Analog clock: a clock that is not digital.
Centimeter (cm): a unit of measurement (e.g., width of a staple).
Compose: change 10 smaller units for 1 of the next larger unit on the place value chart.
Divide: break apart into equal groups.
Estimate: approximation of the value of a quantity or number, i.e. “I estimate there are ______ marbles in the jar”.
Horizontal: with reference to how an equation is written.
Measure: a quantity representing a weight or liquid volume or the act of finding the size or amount of something.
Mental math: calculations performed in one’s head, without paper and pencil.
Meter (m): a unit of measurement (e.g., height of a kitchen counter).
Minute: a unit of time, 1 minute = 60 seconds, 60 minutes = 1 hour.
Multiply: putting together equal groups, repeated addition (i.e. 2 x 2=4).
Number line: a line marked with numbers at evenly spaced intervals, and may be vertical or horizontal.
Rename: regroup units.
Simplifying strategy: transitional strategies that move students toward mental math e.g., make ten to add 7 and 6, (7+3)+3=13.
Unbundle: regroup units (e.g., 1 ten for 10 ones).
Vertical: with reference to how an equation is written; equations solved using the standard algorithm are typically written vertically.
