The student uses patterns to solve problems. Clarifying Activity Students use counters to build the first three triangular numbers.
Students then use geometric and number patterns to predict the next three triangular numbers.

The student uses lists, tables, and charts to express patterns and relationships. Clarifying Activity Students identify and extend the pattern in the pairs of related numbers in the chart in 3.7A, e.g. for each batch of cookies you need 3 eggs, so 10 batches of cookies will take 30 eggs.
