Grade 6 patterns start to look like algebra. Ontario expectation C1.1 asks students to identify and describe patterns, including patterns represented by algebraic expressions. The printable preview still extends a list: 9, 31, 53, 75, and a rule stated in words, start at 4 and add 16, asking for the 12th term. Then the rule becomes an equation. Students find y when y = 5x + 3 and x = 8, evaluate 2n + 14 when n = 7, and solve 2x = 22. A growing list with a gap is still there for students who need the pattern before the variable. Input-output tables that stop at the next output, without an equation, are the Grade 3 patterns page.
