Day 70 and 71 Cartesian Cartoons

6th Grade Math Standards: 6.NS.6 Understand a rational number as a point on the number line. Extend number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with negative number coordinates.
a. Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself, e.g., –(–3) = 3, and that 0 is its own opposite.
b. Understand signs of numbers in ordered pairs as indicating locations in quadrants of the coordinate plane; recognize that when two ordered pairs differ only by signs, the locations of the points are related by reflections across one or both axes.
c. Find and position integers and other rational numbers on a horizontal or vertical number line diagram; find and position pairs of integers and other rational numbers on a coordinate plane.

The Learning Objective: Locate points on a coordinate plane

Assessment: The cartoons were collected and graded for accuracy.

Agenda:

1. Self-Assessment
2. Review the quiz on coordinate plane
3. Review the weekly quiz
4. Read through the Cartesian Cartoon rubric
5. Do an example Cartesian Cartoon (modeling) for the class
6. Students picked what cartoon they wanted
7. Students completed the cartoon
8. If students finished early, they could do a second or a third

Glass-Half Full: With three days before vacation, it is often the case that students are off the walls with energy during this time of the year. Today this was a calming activity that still covered the curriculum in the sixth grade. I also had the ability to work with students one on one at the back of the room on this standard or other standards that they happened to be struggling with.

Regrets: I should have made things more interesting and challenging for students that finished early by having them print a picture of their choosing on graph paper and tell how to construct that picture by writing the necessary coordinates.

Link of the Day: Steve Wyborney is breaking down how to step into the classroom into 6 steps. This is the first step. I like how the three teachers come into the classroom together and have a chance to breakdown what happened together. For this to ultimately be successful though it is important that the teacher they are observing is ok with the observation and on board with the fact that everyone, including he or she, is in this to get better not to be judged.
