Saxon 3 Math Vocabulary Lessons 51 - 90

Front

addition algorithm

Back

A step-by-step procedure used to perform addition.

This is correct: Adding 23 + 15 using the column method.
This is not correct: Adding 23 + 15 by guessing the answer without any steps.

Front

consecutive number

Back

Numbers that follow each other in order without gaps.

This is correct: 1, 2, 3, 4, 5 (These numbers are consecutive because they follow each other without any gaps.)

This is not correct: 1, 3, 5, 7 (These numbers are not consecutive because there are gaps between them.)

Front

divide

Back

To separate or split into parts or groups.

This is correct: If you have 8 apples and you divide them equally among 4 friends, each friend gets 2 apples.

This is not correct: If you have 8 apples and you eat all of them yourself, you are not dividing them.

Front

division bar

Back

The line or symbol used to separate the dividend and the divisor in a division problem.

This is correct: In the division problem 12 ÷ 3 = 4, the '÷' symbol is the division bar.

This is not correct: In the addition problem 5 + 2 = 7, there is no division bar because it is not a division problem.

Front

division box

Back

A method or tool used to organize division calculations.

This is correct: Using a division box to divide 24 by 6 to get 4.
This is not correct: Using a division box to multiply 3 by 5.

Front

equal groups

Back

Groups that have the same number of objects.

This is correct: If you have 3 bags and each bag has 4 apples, then you have equal groups because each bag has the same number of apples.

This is not correct: If you have 3 bags and one bag has 3 apples, another has 4 apples, and the last one has 5 apples, then you do not have equal groups because the number of apples in each bag is different.

Front

line of symmetry

Back

A line that divides a figure into two mirror-image halves.

This is correct: A butterfly's wings have a line of symmetry down the middle.
This is not correct: A triangle with all sides of different lengths does not have a line of symmetry.

Front

quotient

Back

The result of division.

This is correct: If you divide 10 by 2, the quotient is 5.
This is not correct: If you add 10 and 2, the quotient is 12.

Front

symmetric design

Back

A design that is balanced and identical on both sides of a central line.

This is correct: A butterfly's wings are symmetric because they look the same on both sides.

This is not correct: A tree is not symmetric because its branches and leaves are different on each side.

Front

algebra

Back

A branch of mathematics dealing with symbols and the rules for manipulating those symbols.

This is correct: Solving 2 + x = 5 to find out what number x is.
This is not correct: Counting 1, 2, 3, 4, 5.
