An arrangement of objects in rows and columns. All the rows have the same number of objects. All the columns have the same number of objects.
used in:
A way to show data using the height or length of rectangles to represent how many in each group or category.
used in:
The bottom part of a fraction that tells how many equal parts the whole was partitioned into.
used in:
An operation for finding the number of groups or finding the size of each group when we share, or separate a total into groups of equal size.
used in:
The number we are dividing by, which can represent the size of the groups or the number of groups. Example: When 37 is divided by 5, we call 5 the divisor.
used in:
One part of a whole that is divided into 8 equal parts.
used in:
A statement that includes an equal sign (=). It tells us that what is on 1 side of the equal sign is equal to what is on the other side.
used in:
Fractions that have the same size and describe the same point on the number line. Example: \(\frac{1}{2}\) and \(\frac{2}{4}\) are equivalent fractions.
used in:
A way of writing a number as a sum of the values of the digits.
Example: 482 written in expanded form is \(400 + 80 + 2\).
used in:
A statement that has at least 2 numbers and at least 1 math operation (such as addition, subtraction, multiplication and division).
used in:
A number that is multiplied by at least 1 other whole number to get a product.
used in:
A number used to describe the parts of a whole that has been partitioned into equal parts.
used in:
A weight unit that is part of the metric measurement system.
There are 1,000 grams in 1 kilogram.
used in:
The part of a picture graph that tells what each picture or symbol represents.
used in:
A weight unit that is part of the metric measurement system.
There are 1,000 grams in 1 kilogram.
used in:
A liquid volume unit that is part of the metric measurement system.
used in:
A number expressed as a whole number and a fraction less than 1.
used in:
An operation for finding the total number of objects when we have a certain number of equal groups.
used in:
The top part of a fraction that tells how many of the equal parts are being described.
used in:
Grouping symbols that can be used in expressions or equations, such as: \((3 \times 5) + (2 \times 5), (24 \div 2) + 5 = 17\).
used in:
The boundary of a flat shape. We can find the length of the perimeter by finding the sum of the side lengths of the shape.
used in:
A way to show data using pictures or symbols to represent how many in each group or category.
used in:
The result of multiplying some numbers.
used in:
A flat shape with 4 straight sides and 4 angles.
used in:
The result of dividing one number by another.
used in:
A quadrilateral with 2 pairs of parallel sides and 4 right angles.
used in:
A quadrilateral with 4 equal sides.
used in:
The angle made by 2 sides that meet like they do in a rectangle.
used in:
To say which number a given number is closer to. Example: For 182, the number 180 is the closest multiple of 10, and 200 is the closest multiple of 100. We can round 182 to 180 (if rounding to the nearest ten) or 200 (if rounding to the nearest hundred).
used in:
A number line on one side of a bar graph that tells what data value each rectangle represents.
used in:
A bar graph marked in multiples of some number other than 1.
used in:
A picture graph where each picture represents an amount other than 1.
used in:
One part of a whole that is divided into 6 equal parts.
used in:
A quadrilateral with 4 equal sides and 4 right angles.
used in:
A square with side lengths of 1 centimeter.
used in:
A square with side lengths of 1 foot.
used in:
A square with side lengths of 1 inch.
used in:
A square with side lengths of 1 meter.
used in:
A flat shape with 3 straight sides and 3 angles.
used in:
A fraction with a numerator of 1.
used in:
The amount of liquid it takes to completely fill a container.
