Mathematics Clarifying Activities for Grade 3 (continued) Geometry and spatial reasoning. The student uses formal geometric vocabulary. The student is expected to: (A) name, describe, and compare shapes and solids using formal geometric vocabulary. Clarifying Activity Each student makes a shape on a geoboard. The teacher sorts the shapes into two groups according to a secret geometric attribute, e.g. closed shapes vs. shapes that are not closed, shapes with right angles vs. shapes with no right angles, etc. Students analyze the shapes in each group, use formal geometric vocabulary to write a summarizing statement about each group, share their statements, and discuss them. Clarifying Activity Students classify geometric solids (prisms, cones, cylinders, pyramids, spheres) according to characteristics such as numbers of faces, shapes of faces, numbers of edges, numbers of vertices.

Lesson Overview Students use one-inch square tiles and paper ruled into one-inch squares to solve the problem of finding all the possible ways to arrange five squares into shapes called pentominoes. Mathematics Overview Students use an organized search and identify congruent and non-congruent shapes in order to determine when they have found all of the pentominoes.

Information on Pentomino Puzzles A pentomino is an arrangement of 5 unit squares (or sometimes cubes) that are joined along their edges. Up to isomorphism (rotating and flipping), there are 12 possible shapes, which are illustrated below. Each piece is labelled by the letter that most accurately reflects its shape. V T W X U Z F P I N Y L The problem is to fit the 12 pentomino pieces into various shapes, often rectangles. The rectangle shapes that fit all 60 squares are of sizes 3x20, 4x15, 5x12, and 6x10. Here's a solution to the 6 by 10 puzzle using the letter encoding. NFVVVYYYYI NFFFVLLYZI NNFXVLZZZI PNXXXLZWTI PPUXULWWTI PPUUUWWTTT Much better looking is the same solution using tables and gifs.

27. Elementary Level Mathematics: Grade Five (Strand: Geometry) pentominoes can be used effectively to examine the concepts of A GeometryFair is an exciting, motivational activity to involve many classes (even http://www.sasklearning.gov.sk.ca/docs/elemath/g542note.html

Grade Five Strand: Geometry Topic: Plane Instructional Notes G-13 Begin a display of objects that suggest both 3-D and 2-D shapes. Ask students to add to the collection. They may use their critical and creative abilities to classify the items. Always encourage students to identify as many properties as possible. G-13(c) To identify properties of geometric figures, present open-ended tasks. e.g., Use a geoboard and elastics to make as many different five-sided figures as possible. Record your figures on dot paper. G-19 Have students share their thinking and the strategies they used as they experiment with various geometrical concepts. Students may still work with squares and triangles through matchstick or toothpick games. make 2 equilateral triangles using 5 toothpicks make 5 triangles using 9 toothpicks, then take away 3 toothpicks leaving 1 triangle make 4 squares using 12 toothpicks Concept attainment can be used to develop many geometrical concepts such as shapes, lines, and congruency. G-22(b) At the Elementary Level, the terms flips and turns can be used in conjunction with reflections and rotations. Reflections and rotations reinforce the concepts of congruency and symmetry.

Grade Three Strand: Geometry Topic: Plane Instructional Notes G-12 Students should experience working with many different 2-D geometric manipulatives. This offers them a broader understanding of the concepts. G-13(b) Ask students to collect or record examples of geometric figures in the environment. G-14 Use items such as beads, beans, and corn that are strung together and have students create the outlines of various geometric shapes. G-16 Students should be allowed to discuss the relationships and properties of the geometric figures using their own language. G-18 Ask students how they can tell if two shapes are congruent. They may be encouraged to talk about it with a partner before sharing with the entire class. Ask students to create a shapes mural based on a book read to the class or on a class activity. Students could use a theme from another subject area. G-19 Geoboards and elastics offer students the creative transition between the concrete (hexagon attribute block) and the pictorial (picture of a hexagon). Geoboards can be used for developing a wide range of mathematical concepts such as shape, congruency, fractions, symmetry, and measurement. Encourage students to be creative.

All Topics This page collects in one place all the entries in the geometry junkyard. Adventitious geometry . Quadrilaterals in which the sides and diagonals form more rational angles with each other than one might expect. Dave Rusin's known math pages include another article on the same problem. Almost research-related maths pictures . A. Kepert approximates superellipsoids by polyhedra. Angle trisection , from the geometry forum archives. Anna's pentomino page . Anna Gardberg makes pentominoes out of sculpey and agate. Antipodes . Jim Propp asks whether the two farthest apart points, as measured by surface distance, on a symmetric convex body must be opposite each other on the body. Apparently this is open even for rectangular boxes. Antiprism (Archimedean) . Some self-explanatory pictures from Eric Weisstein's treasure trove of mathematics. Aperiodic space-filling tiles: John Conway describes a way of glueing two prisms together to form a shape that tiles space only aperiodically. Ludwig Danzer speaks at NYU on various aperiodic 3d tilings including Conway's biprism.
