- Analogy
- A comparison stating that two pairs share the same relationship, written as A is to B as C is to D. The second pair must copy the first pair's link exactly.
- Antonym
- A word with the opposite meaning of another word, such as hot and cold or empty and full. Opposite pairs are a frequent relationship in verbal analogies.
- Synonym
- A word that means nearly the same as another word, such as big and large or happy and glad. Synonym pairs often appear in classification and analogy items.
- Category word
- A word naming the group that members belong to, such as fruit for apple or vehicle for bus. Classification items ask which word does not fit the shared category.
- Part to whole
- A relationship in which one word names a piece of the other, such as wheel to car or petal to flower. This link is common in Grade 2 verbal analogies.
- Sentence completion
- Choosing the missing word so the whole sentence makes sense and stays grammatically correct. The blank's role as noun, verb, or describing word guides the choice.
- Subject and object
- The subject performs the action and the object receives it. In 'The dog chased the cat,' the dog is subject and the cat is object, so swapping them changes the meaning.
- Odd one out
- The item in a group that lacks the shared feature the other three have. The remaining three must all fit one nameable category.
- Young to adult
- A relationship pairing a baby animal with its grown form, such as puppy to dog or kitten to cat. It appears often in early verbal analogy questions.
- Action word pairs
- Verb relationships link a tool or body part to what it does, such as hammer to pound or eye to see. The second word completes the action of the first.
- Number series
- A list of numbers following a rule, where the next number must be found. Common rules add or subtract the same amount each step, or skip-count by 2s, 5s, or 10s.
- Skip counting
- Counting forward by a fixed jump larger than one, such as 5, 10, 15, 20. Recognizing skip-count patterns makes number series items quick to solve.
- Number analogy
- A pair of numbers related by an operation, matched by a second pair using the same operation. If 3 becomes 6 by doubling, then 5 becomes 10 by doubling.
- Doubles fact
- A sum of a number with itself, such as 6 + 6 = 12 or 8 + 8 = 16. Doubles anchor mental arithmetic and help solve near-doubles like 6 + 7.
- Near doubles
- A sum close to a doubles fact, solved by doubling then adjusting by one. For example, 6 + 7 = 6 + 6 + 1 = 13.
- Place value
- The value a digit has because of its position. In 47, the 4 means 4 tens (40) and the 7 means 7 ones, so 47 = 40 + 7.
- Tens and ones
- The two parts of a two-digit number. The left digit counts groups of ten and the right digit counts leftover ones, as in 35 = 3 tens + 5 ones.
- Balance equation
- A statement that both sides are equal, like 4 + 3 = 5 + 2. It stays true only when the same change is made to both sides.
- Comparison symbols
- The signs greater than and less than. The open wide side always faces the larger number, so 8 > 5 and 5 < 8 state the same fact.
- Alternating rule
- A series pattern that switches between two rules, such as +2, +5, +2, +5. Checking every other number reveals the two separate patterns.
- Growing jumps
- A series where the amount added changes each step, as in +1, +2, +3. The jumps themselves form a pattern that predicts the next number.
- Even and odd
- Even numbers can be split into two equal groups (2, 4, 6); odd numbers leave one extra (1, 3, 5). The ones digit alone tells which an number is.
- Figure analogy
- A visual comparison applying the same change to a second figure that turned the first into the second, such as rotating, shrinking, or recoloring it.
- Figure classification
- Choosing the figure that lacks the shared visible feature of the others, such as same shape, same number of sides, or same shading.
- Paper folding
- A puzzle where paper is folded and a hole is punched, then the unfolded sheet is shown. Each layer the punch passes through produces one hole.
- Reflection
- A mirror flip of a figure across a line, which reverses its left-right or top-bottom orientation. A reflected figure cannot be matched by rotation alone.
- Rotation
- Turning a figure around a point without flipping it. A quarter turn changes a shape's orientation but keeps its size, shape, and handedness the same.
- Line of symmetry
- A line along which a figure can be folded so both halves match exactly. A square has four such lines; a circle has infinitely many.
- Attribute counting
- Tallying a visible feature such as sides, corners, dots, or stripes. The count often forms the pattern that predicts the next figure in a series.
- Shape series
- A sequence of figures changing by one repeated step, such as gaining one side each time or turning a quarter turn each time.
- Position pattern
- A rule based on where figures sit rather than what they look like, such as alternating inside and outside or moving left to right across a row.
