What is Additive Thinking? When students use additive thinking, they consider the change in only one set of data. For instance, in the examples below, students can recognize that the pattern increases by 3 blue tiles each time, or that the value in the right column increases by 3 each time. Students who utilize only additive thinking do not recognize the co-variation between the term number and tiles, or between the two columns in the table. +3 1 2 3 +3 +3 +3
Multiplicative Thinking • Understanding the co-variation of two sets of data • For instance, in this pattern, the mathematical structure can be articulated initially by a pattern rule, number of tiles = term number x3+1 • In older grades more formal symbolic notation can be used, y=3x+1 • This allows students to confidently predict the number of tiles for any term of the pattern 1 2 3
Tiles = position number x1+1 Tiles = position number x3+1 Tiles = position number x5+1 What is similar in the 3 rules? What is different? What is similar in the 3 patterns? What is different? What is similar about the trend lines on the graph? What is different?
Tiles = position number x3+2 Tiles = position number x3+6 Tiles = position number x3+9 What is similar in the 3 rules? What is different? What is similar in the 3 patterns? What is different? What is similar about the trend lines on the graph? What is different?
