Number Patterns: These are sequences of numbers that follow a specific rule or operation. For example, the sequence 2, 4, 6, 8, 10 follows the pattern of adding 2 to the previous number.
Repeating Patterns: These are sequences of elements that cycle or repeat in a consistent manner. For example, a sequence of red, blue, green, red, blue, green forms a repeating pattern.
Understanding regular patterns in math helps develop problem-solving skills, logical reasoning, and critical thinking. These skills are essential for success in various areas of mathematics and in real-world applications.
Analyze characteristics and properties of two- and three-dimensional geometric shapes and develop mathematical arguments about geometric relationships.
Identify, compare, and analyze attributes of two- and three-dimensional shapes and develop vocabulary to describe the attributes.

Measurement: As part of understanding two-dimensional shapes, students measure and classify angles.
