Multiplication is a mathematical operation that represents the total of one number added to itself a certain number of times. For example, 3 × 7 means adding 3 seven times.

A number line is a straight line with numbers placed at equal intervals along its length. It helps in visualizing numbers and performing operations like addition and subtraction.

A dot plot is a statistical chart that uses dots to represent the frequency of data points. Each dot represents one count of a value.

A fraction represents a part of a whole. It is written as 'a/b', where 'a' is the numerator (part) and 'b' is the denominator (whole).

Equivalent fractions are different fractions that represent the same value or proportion of a whole. For example, 1/2 and 2/4 are equivalent.

To compare numbers, you can use symbols like '>', '<', or '='. For example, 5 > 3 means 5 is greater than 3.

A table organizes data into rows and columns, making it easier to read and compare information.

Time duration is the total time taken for an event to occur, measured in hours and minutes.

To find the end time, add the duration of the event to the start time. For example, if a movie starts at 7:00 PM and lasts 1 hour 15 minutes, it ends at 8:15 PM.

A mathematical model is a representation of a real-world situation using mathematical concepts and language, often used to solve problems.
