Aligned Standard

M.EE.7.EE.2: Identify an arithmetic sequence of whole numbers with a whole number common difference.

Grade Level Standard

This is aligned with the following California State Standards:

  • 7.EE.2 - Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related. For example, a + 0.05a = 1.05a means that increase by 5% is the same as multiply by 1.05.

Linkage Level Descriptions

Initial Precursor

Arrange objects in a specific order by following a specific rule (e.g., arrange objects from the largest to the smallest size). Group like items by attributes such as size, shape, and color. Contrast or distinguish objects based on attributes such as shape, size, texture, and numerical pattern.

Distal Precursor

Recognize patterns (i.e., repeating, growing, shrinking) involving numbers or letters (e.g., a, b, b, a, b, b...; 2, 5, 8, 11...). Identify a sequence as an ordered list of numbers that adheres to a common rule between corresponding numbers (e.g., 2, 4, 6, 8...).

Proximal Precursor

Recognize a growing pattern as a pattern that increases (e.g., 3, 6, 9, 12...), and a shrinking pattern as a pattern that decreases (e.g., 12, 10, 8...).

Target

Recognize arithmetic sequences as sequences where the difference between two consecutive terms is constant (e.g., 1, 4, 7, 10...).

Successor

Recognize the recursive rule in arithmetic sequences by determining how each term in the sequence differs from the preceding term (e.g., the recursive rule in the sequence 2, 4, 6, 8... is add 2).
