Add (+):

To combine.

Addend:

Any number being added.

Addition:

An operation that gives the sum of two or more numbers.

Colored Chips:

The small round chips used for various games in Giggle Facts.

Commutative Property:

A rule used in Addition that states that the order of the numbers being added does not change the sum (ex: 5+3 is the same as 3+5).

Computation:

The process of computing or finding a numerical result, usually by adding, subtracting, multiplying or dividing.

Difference:

The answer to a Subtraction question.

Digit:

Any one of the ten symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9.

Doubles:

Any of the Addition Facts that have two of the same numbers: (0+0, 1+1, 2+2, 3+3, 4+4, 5+5, 6+6, 7+7, 8+8, 9+9).

Doubles Plus 1: 

An Addition strategy building on the Doubles strategy.  When two consecutive numbers are added (ex: 5+6), the student can think of the Doubles of the smaller number (5+5 =10), and add one more (to get 11).

Face-cards:

The Jacks, Queens, and Kings in a deck of cards. 

Fact: 

An Addition Fact is any 2 whole numbers added together, up to and including 10+10.  A Subtraction Fact is any 2 numbers subtracted one from the other, from 20 down.  Facts should be committed to memory for quick and easy recall.

Fact Family: 

A group of 4 Facts related by Addition and Subtraction. (ex: 5+2=7, 2+5=7, 7-5=2, 7-2=5 are all in the same Fact Family).  The Doubles are the exception, where only two Facts are created.  There are three members of a Fact Family (Ex: 2, 5, 7) .  Fact Families enable students to see how Addition and Subtraction are connected.  Understanding these connections makes learning the Subtraction Math Facts easier.

Fact Triangle: 

A way to display the 3 digits in a Fact Family so the student can see the relationship between the 3 numbers. 

Flashcards:

A traditional tool used for learning Addition and Subtraction Math Facts by rote memory (memorization).  All the Math Facts are printed individually on small cards, and the student is exposed to the cards repeatedly in an effort to have him state the answers as quickly as possible.    

Game Piece: 

The colored pawn used for moving around a game board.

Identity Property of Addition: 

If you add zero to a number, the sum is the same as that given number.  So, 6+0=6 and 0+6=6. 

Level: 

Giggle Facts has been divided into 26 steps or Levels, from Level A to Z.  Each Level builds on the next one, so it is important to progress through the Levels in order.

Manipulatives: 

Any of the learning aids included in Giggle Facts used to play the games and complete the activities (Dice, Dominoes, Playing Cards, Game Pieces, Colored Chips, Dry Erase marker, stickers, and the Giggle Bag).

Math Fact: 

An Addition Fact is any 2 whole numbers added together, up to and including 10+10.  A Subtraction Fact is any 2 numbers subtracted one from the other, from 20 down.  Facts should be committed to memory for quick and easy recall.

Mental Math: 

A question that can be answered in the student’s head, using a combination of Math Fact Knowledge and Number Sense.

Number Line: 

A diagram that represents numbers as points on a line.

Number Sense:

A knowledge of how numbers are ordered, and of the relationship that exists between numbers.

Number Sentence:

An equation or inequality with numbers.

Numeracy:

"Numerical literacy"; the ability to reason with numbers, and to apply other mathematical concepts and math principles. 

One-to-One Correspondence: 

The ability to match one object to another object.  For example, the student should be able to say “1,2,3,4…” while counting or moving one object for each number said aloud.  If she mistakenly counts an object twice or skips one of the objects as she counts, she has not mastered one-to-one correspondence. Students must be able to match one object to each number counted before beginning Giggle Facts.

Strategy:
A method or trick to help students learn the Math Facts. 
Subtract (-):

See subtraction.

Subtraction:

An operation that gives the difference between two or more numbers.  Subtraction is also used to compare two (or more) numbers.

Sum: 

The answer to an Addition question.

Tally Mark: 

A mark used to keep track of counting.  Vertical bars are made for each number, and a diagonal bar is made for every 5 numbers, forming bundles of 5s.  

Turnaround:  The numbers in an Addition Fact can be switched around and added to get the same answer (ex:  3+7 = 7+3).  This is formally known as the “Commutative Property”.  This is useful when the student is still counting to find the answer; it is faster to begin with the larger number (ex: starting at 7 and counting up 3, instead of starting at 3 and counting up 7).
