Number Pattern Relationships
数字规律关系
Description
Generate two numerical patterns using two given rules; identify relationships between corresponding terms; form ordered pairs and graph them on a coordinate plane
Mastery Evidence
- Generate sequences starting at 0 with rules 'add 3' and 'add 6'; observe terms in one are twice the other
- Form ordered pairs from corresponding terms and plot them on a coordinate grid
- Explain informally why the relationship between the two sequences holds
Assessment Prompt
Can your child follow two number patterns at once — for example, "add 2" and "add 4" — pair up the matching terms, and plot those pairs as points on a graph?
