ISEE Primary 2 cheat sheet

The main idea is what the whole passage is mostly about; a detail supports the main idea but covers only one small part.

To find a stated detail, locate the exact words or a close synonym in the passage and reread that sentence before choosing.

Story order (first, next, then, last) can be checked by asking what happened before and after a given event.

A character's feelings are shown by what the character says, does, or thinks; the passage usually does not name the feeling directly.

Context clues: a word's meaning can be worked out from the sentence around it, especially examples after 'like' or 'such as'.

Retelling should include the important events in order and leave out small details that do not change the story.

A prediction must be supported by clues in the text, not by what the reader would prefer to happen.

When two answers both seem true, the correct one answers the exact question asked and is directly supported by the passage.

Place value: in a three-digit number, the digits name hundreds, tens, and ones, so 472 = 400 + 70 + 2.

Comparing numbers: compare the hundreds digit first, then the tens, then the ones; 305 < 350 because 0 tens < 5 tens.

Addition and subtraction within 1,000 use regrouping: 10 ones make 1 ten and 10 tens make 1 hundred.

Skip counting by 2s, 5s, 10s, and 100s builds the patterns used for early multiplication and for counting money.

For a word problem, identify the known amounts and whether the unknown is a total (add) or a missing part (subtract).

Repeated addition such as 4 + 4 + 4 equals 3 groups of 4, which is the same as 3 × 4 = 12.

Length is measured by lining up the object's end with the zero mark on a ruler and reading the other end in the same unit.

A shape's sides and corners identify it: triangles have 3 sides, quadrilaterals 4, pentagons 5, and hexagons 6.
