Geometry is the branch of mathematics that studies properties of points, lines, curves, plane figures and solid shapes, as well as their measurement and relationships. Early learners begin to identify shapes and manipulate these shapes to recognize spatial positioning. Students learn about points, lines and angles, and apply reasoning skills to measurement strategies. The coordinate plan is a framework for spatial organization and the foundation for geometric thinking. Scaled drawings can be designed to replicate real-world situations and problems involving shapes and measurement.
Students need multiple opportunities to look at data and be able to determine and word statistical questions. Data should be analyzed from many sources, such as organized lists, box-plots and bar graphs. The standard in these upper grades continues to build good problem-solving skills with informational data. Instructional Strategy 42: Mean and Median Mean and median are two ways for comparing data information. We prepared 200 hot dogs for the football game. We served hot dogs to 100 people. That means that the average number of hot dogs eaten by each person was 2. Why would we want to figure this? Next week is another football game and we know that they have sold more tickets to next week’s game than this week’s. We need to estimate how many people will be buying hot dogs next week and figure an average of 2 hot dogs per person. This gives us a simple example of how an average might be used in a daily living activity. We also hear about an average weight loss on a TV show. We hear about grades based on the average for the semester. The average temperature for the month may be reported by the weatherperson. All of these are examples of ways we may hear information reported as an average. Helping students understand this concept will enable them to visualize the ways these terms are used in daily activities.
