The symbols ∈ (element of) and ∉ (not element of) are used to show if something belongs to a set or not. For example, '3 ∈ {1, 2, 3}' means 3 is an element of the set {1, 2, 3}. '5 ∉ {1, 2, 3}' means 5 is not an element of the set {1, 2, 3}.

The position of a digit in a number that determines its value, e.g., in the number 123, the digit '1' is in the hundreds place, '2' is in the tens place, and '3' is in the ones place.

Understanding that the position of a digit in a number determines its value, e.g., 100 is different from 10 because the digit '1' occupies a different place value.

A Venn diagram is a visual representation of sets using overlapping circles. Each circle represents a set, and the overlapping sections represent the elements that belong to both sets.

The symbol { } represents a set of elements. For example, {1, 2, 3} represents a set containing the numbers 1, 2, and 3.

Skill of accurately identifying the position of digits in a number and their corresponding value within a 3-digit number.

Skill of writing a 3-digit number based on its place value components.

Countable nouns can be counted (like 'apples' - 1 apple, 2 apples), while uncountable nouns can't be counted (like 'water' - you can't say '1 water').

Place value tells you the value of each digit in a number. In the number 123, the '1' is in the hundreds place, the '2' is in the tens place, and the '3' is in the ones place.

A visual tool used to represent numbers by a number of beads on its rods, each rod representing a specific place value.
