7 San Diego City Schools Instruction and Curriculum Division MATHEMATICS CURRICULUM MAP GRADE 5 MODULE 4 GEOMETRY: PLANE AND SOLID FIGURES Modules represent individual units of study that lead to essential learnings THREADS THROUGHOUT THE YEAR- GRADE 5 The threads represent ongoing learning opportunities in which students should be actively engaged throughout all units of inquiry during the entire school year. These items should not be isolated to any one particular unit of inquiry. Students will: Develop understanding of numbers and the number system and use their understanding to solve problems and recognize reasonable results. Develop understanding of and fluency in basic computation and procedural skills. Use mathematical reasoning to solve problems. Communicate their mathematical thinking by using words, numbers, symbols, graphs and charts and translate between different representations. Use equations and variables to express generalizations of patterns and relationships. Develop logical thinking to analyze evidence and build arguments to support or refute a hypothesis. Make connections among mathematical ideas and between other disciplines Develop and use strategies, skills, and concepts to solve problems. Use appropriate tools, including technology, as vehicles to learn mathematical concepts. These are essential learnings that represent bigger ideas/concepts: Students use ordered pairs to locate and describe locations on a 4-quadrant coordinate grid. Students build their spatial sense through geometric experiences. Students transform shapes in a plane or in space and describe the changes as translations (slides), reflections (flips) and rotations (turns). Students visualize, and draw a three dimensional figure from two-dimensional views. Students test figures for rotational symmetry. Students estimate angle size using benchmark angles and use a protractor to measure angle size more accurately. Students test and generalize the number of degrees in the angles of a triangle. Students relate circumference of a circle to perimeter of polygons. Through measurement and observation, students determine the relationship between the radius and diameter of a circle. These are essential questions that learners ask themselves in order to achieve the essential learnings: How do I describe the parts of a graph on a 4 quadrant coordinate plane, and then identify and plot ordered pairs of integers on the graph? *How can I identify, describe and classify plane and solid geometric figures by their properties, including angles and sides? How can I use estimation and measurement with a protractor to classify angles? *How can I identify the parts of a circle and explain the relationship between radius and diameter? *How do I identify similar and congruent figures? *How do I identify and explain lines of symmetry in a polygon? *How do I test a polygon for rotational symmetry? How can I verify that the total number of degrees in the angles of any triangle is 180? How do I identify and draw solid figures from top, side and front views? * Presented in previous grades Resources: Van de Walle: Chapters 19 & 20 (pp & pp ); Mathematics Source Book: (pp and pp ) Reorganized 9/03/04 7

28 DAY: 12 Unit 7: Algebra and Geometry Chapter 26: Classify Plane and Solid Figures LESSON 26.4, Pg MATERIALS: LESSON FOCUS: CALIFORNIA STANDARDS: PURPOSE OF LESSON: LAUNCH: Introduce students to concepts. EXPLORE: Work with the concept. Focus on student s doing mathematics. Rectangular prisms and cylinders of different sizes: 1 for every pair Collection of pyramids, prisms that are not rectangular, cones and spheres. Solid Figures MG 2.0: Students identify, describe, and classify the properties of, and relationships between, plane and solid geometric figures. AF 1.2: Use a letter to represent an unknown number; write and evaluate simple algebraic expressions in one variable by substitution. :. Identify solid figures Solids are named according to the shape of the base of the prism or pyramid. Prisms and pyramids have 2 bases that are congruent and parallel. Learn, Pg. 486: Box, Ball, or Can. Use a transparency of the picture of the Rock & Roll Hall of Fame to engage students in identifying shapes. Discuss observed attributes. Use Guided Instruction questions (T.E. Pg ) but if possible use solids, not just pictures of solids in the book, for students to examine. Model orally giving a description of a polyhedron using the charted vocabulary. As you discuss the vocabulary used, create a class chart of words and sketches to illustrate meaning. Then partners take turns describing a different polyhedron using the math vocabulary. Classify Solid Figures, Pg See bullets top margin TE Pg. 487 to guide discussion. Discuss examples shown in the pictures. Practice & Problem Solving, Pg. 488 # Do with students and discuss. Reorganized 9/03/04 28

29 PRACTICE: Focus on Communication and Representation. SUMMARIZE: Connect purpose to activities. Practice & Problem Solving, Pg. 488 # Discuss responses. Ask students to make a table just like the one on Pg. 488, for # Students work with partners to fill in the table while observing the solid figures. Give each group two or three solid figures to identify, and count bases, faces, edges and vertices. Pass the figures from table to table. ASSESS, TE Pg. 489: DISCUSS ASSESS, TE Pg. 489: WRITE: Sketch it. Share responses and sketches. HOMEWORK: Mixed Review and Test Prep: Pg. 489: ROUTINES: o Choose from: o Routines in Harcourt Training and Routines already introduced. o Include ordering positive and negative integers when using a blank number line. o Include addition and subtraction of integers using models or mental math. o Tables from Lesson 24.3 and Function Tables from Pg o Math Detective, Pg. 496: 8 different problems to use one at a time.

TR32 Grid Paper connecting cubes for teacher EXPLORE: Work with the concept. Focus on student s doing mathematics. PRACTICE: Focus on Communication and Representation. SUMMARIZE: Connect purpose to activities. TR32 Grid Paper, one piece for plastic cover to be reused and two to be consume by each student. Cubes for students and teacher. Draw and Identify Solid Figures from Different Views MG 2.3: Visualize and draw two-dimensional views of threedimensional objects made from rectangular solids. MG 2.0: Students identify, describe, and classify the properties of, and relationships between, plane and solid geometric figures. : :. Draw and identify solid figures from different views Solids can be recognized from 3 views: front, top and side. Alternative Teaching Strategy: T. E. Pg. 490 Explore, Pg Ask students to practice the views shown on a piece of grid paper. Try It, Pg Students may use the same grid paper used for Explore. Connect, Pg Discuss with students. Practice, Pg Partners choose two from #1-4 and draw the views. Practice, Pg. 491 #5-9. Students use grid paper to sketch views. Partner Work: Build a figure with fewer than 12 cubes and draw the three views. Trade drawings with a pair from another table and try to build the figure using the drawings of the three views. Discuss Whole Group: What did you discover about the similarities and differences between drawing three views and building figures using the drawings? Which was easier? Why? Discuss strategies they used. HOMEWORK: Mixed Review and Test Prep, Pg. 491 Reorganized 9/03/04 30
