Area

Expression A mathematical phrase that combines numbers (1,2…) and/or variables (y,z,x…) using operations (+ - x ÷).

Composite Number

Product The answer to a multiplication problem.

Even Numbers

Expressions = 12 6 (3) + 5 = 23 9 x 8 = 72

Factors 72 = 1, 2, 3, 6, 8, 9, 12, 24, 36,72 24 = 1, 2, 3, 4, 6, 8, 12, 24 So 12 x 6= 72, 24 x 3= 72, 36 x 2 = 72 So 12 x 2 = 24, 4 x 6 = 24, 8 x 3 = 24

Histogram

Perimeter The distance around a figure on a flat surface.

Remainder The amount left over when the divisor does not divide into the dividend exactly.

Odd Number

Perimeter

Scatter Plot A graph made by plotting ordered pairs in a coordinate plane to show the correlation between two sets of data.

Place Value 25 Ones 248 Hundreds 2,397 Thousands 2.8 Tenths 3.85 Hundredths

Rectangular Array A visual model for multiplication. Example:

Prime Numbers 2, 3, 5, 7, 11, 13, 17, 19

Product 4 x 4 = 16 5 x 8 = 40

Prime Number A positive integer with exactly two factors, the number itself and 1.

Rectangular Array

Place Value The value of where the digit is in the number.

What is 5? Remainder

Scatter Plot

Area The number of square units needed to fill up a region on a flat surface

Composite Number A number with more than two factors

Even Number A whole number that is divisible by two with no remainder

Factor One of two numbers multiplied together to form a product. Factor X Factor=Product

Histogram A way to display data, much like a bar graph in that the height of the bars is proportional to the number of elements, but it displays ranges of data instead of specific measurements.

Multiples 5 = 5, 10 15, 20, 25, 30, 35 40… 7 = 7, 14, 21, 28, 35, 42, 49… 8 = 8, 16, 24, 32, 40 48…

Multiple The product of multiplying any two whole numbers (not zero).

Odd Number An integer that cannot be evenly divided by two.
