Standard 5: Use Appropriate Tools Strategically

Clip 4/13: Standard 5: Use Appropriate Tools Strategically Using Numeric Pattern Part 2


Mathematically proficient students consider the available tools when solving a mathematical problem. These tools might include pencil and paper, concrete models ... Proficient students are sufficiently familiar with tools appropriate for their grade or course to make sound decisions about when each of these tools might be helpful...

Fran Dickinson leads a lesson on numeric patterning, helping students to investigate a numeric pattern and to generalize what they see happening as the pattern grows. In this clip, Dickinson tells his students that “the first step is to do a pictorial representation… I want you to play around with the tiles, and sketch out what you see happening in those first three patterns, but I want you to pay attention to color-coding. You’re free to use those tiles like I said, or markers if you need them, I can make those available as well." This clip is also indicative of standard 1 (make sense of problems & persevere in solving them).
