5th Grade STAAR Math Review #4

Front

What is the order of operations in mathematics?

Back

The order of operations is a set of rules that determines the sequence in which calculations are performed. The acronym PEMDAS helps remember the order: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is a coordinate grid?

Back

A coordinate grid is a two-dimensional plane formed by the intersection of a horizontal line (x-axis) and a vertical line (y-axis). Each point on the grid is defined by an ordered pair (x, y).

Front

How do you calculate the total cost of multiple items?

Back

To calculate the total cost, multiply the price of each item by the quantity purchased and then add the costs together.

Front

What is a dot plot?

Back

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

Front

What does it mean to graph a point on a coordinate grid?

Back

Graphing a point means to locate it on the coordinate grid using its x and y coordinates. The x-coordinate indicates the horizontal position, and the y-coordinate indicates the vertical position.

Front

What is mass in terms of measurement?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg) or grams (g).

Front

How do you estimate the sum of two numbers?

Back

To estimate the sum, round each number to the nearest ten or hundred and then add the rounded numbers together.

Front

What is multiplication?

Back

Multiplication is a mathematical operation that represents the repeated addition of a number. For example, 4 × 3 means adding 4 three times (4 + 4 + 4).

Front

What is the significance of the origin in a coordinate grid?

Back

The origin is the point where the x-axis and y-axis intersect, represented by the coordinates (0, 0). It serves as the starting point for graphing points.

Front

How do you find the total mass of multiple objects?

Back

To find the total mass, add the mass of each individual object together.
