1 Shape City
Start the conversation by introducing the concept of designing a city. Use some prompting questions such as:
- What things to city planners need to keep in mind when they design a city?
- What kinds of lines need to be drawn
Introduce the idea that students will be creating a digital city using the geometric concepts of the unit. Set the criteria consistent with the grade outcomes (ie; your city must have 3 parallel lines, 2 perpendicular lines, contain 2 rhombuses, etc...)
*students can use technology like popplet to record their ideas of what a city should contain, later they will be able to reorganize their thoughts to structure their city
Masters of the Universe!
You will demonstrate your understanding of the geometric concepts and create a digital city!
Present the outcomes clearly to the students - posting them as I can statements - ie: I can identify a perpendicular line. *as much of this is vocabulary instruction many students will know the concepts or will use their curiosity to discover the answers using the guided math in the next step
Using Google forms create a pre-test students can test their knowledge.
Based on the information collected, you can structure a guided math scenario where you can provide some direct instruction of misconceptions or introduce concepts not known by many.
Test your knowledge!
I know you already know a lot about shapes, lines and geometric concepts. Lets test your knowledge!
3 Guided Math Ideas
Guided Math - have students rotate through stations to discover some of the math concepts they are missing (previously discovered in the pretest)
Station ideas: Using the app The Land of Venn, Crafty Cut, your school resources and a station where you can clear up/teach any concepts not understood. Have students rotate through.
Give students a Google Doc with all the outcomes of the grade written as I can statements - you can use this as a self assessment , then as they learn the concepts they can check off their understandings on the doc.
Look at the Google Doc - self assess what you think you already know
|I Can||I Got It||I'm Not Sure||I Need to Learn|
|identify perpendicular lines|
Then, as you learn the concepts, put a date in the box when you think you've mastered the idea.
4 Build a City
Have students work in groups to develop their city. They can use Google Sketch Up to create a 3-D model or Google Drawing canvas to draw a 2-D model or just a piece of poster paper to create their city. Then students will create a presentation (either written, or spoken) describing their city's features including the geometric concepts presented.
Build your city! You may use Google sketch-up, Google draw, another drawing tool of your choice, or poster paper to draw a map of your city. You will be presenting your city to the class.
Have students present their cities. You could choose to record their presentation using ipad camera, or a program like voice thread where students can add mp3's to the screen capture so you can save it all as a movie and view later, or save to share with parents!
*you can also set this up as a challenge and have the "best" city win and do a vote with students
This is your planning team's chance to shine. Present your city to your classmates, remembering to include all of your learned information.
Key Standards Supported
|4.G: Draw And Identify Lines And Angles, And Classify Shapes By Properties Of Their Lines And Angles.|
|4.G.1||Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.|
|4.G.2||Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.|
|4.G.3||Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.|
|5.G: Classify Two-Dimensional Figures Into Categories Based On Their Properties.|
|5.G.3||Understand that attributes belonging to a category of two- dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.|
|5.G.4||Classify two-dimensional figures in a hierarchy based on properties.|
Modeling With Geometry
|HSG.MG: Apply Geometric Concepts In Modeling Situations|
|HSG.MG.1||Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder).★|
|HSG.MG.2||Apply concepts of density based on area and volume in modeling situations (e.g., persons per square mile, BTUs per cubic foot).★|
|HSG.MG.3||Apply geometric methods to solve design problems (e.g., designing an object or structure to satisfy physical constraints or minimize cost; working with typographic grid systems based on ratios).★|
