They attend to properties, namely the number of sides and the ‘sharpness’ of angles at the corners. The student identifies differences between the prototypical hexagon and octagon. They establish the features and properties that are the same for both shapes and those that are different.Ĭlick on the image to enlarge it. The student identifies features and properties of the prototypical hexagon and octagon. Have you tried changing the look of the hexagon and octagon? Do the differences still happen?.What could you find out next? Have you learned anything that will work with other shapes?.How have you convinced Jess she is wrong, and the shapes are different?.How will you convince Jess that the two shapes are different?Īllow ākonga time to check their answers and then either have them pair share with other groups or ask for volunteers to share their solution with the class. A list of different geometric shapes to help you identify 2d and 3d shapes, with properties and images. Zacharia Doar, a 23-year-old Muslim father living in Texas, was stabbed in Austin on February 8 after a protest.How can you make sure that you haven't missed anything?.What is different about the features and properties of both shapes?.Square: A four-sided shape with all sides of equal length and all angles of 90 degrees. Circle: A perfectly round shape with no corners or edges. What is the same about the features and properties of both shapes? List of the 50 Most Popular Shapes with Their Names Definitions and Pictures.Have you recorded as many things as you can about the two shapes?.From this list how will you find differences?Īllow ākonga time to work through their strategy and find a solution to the problem.Should you make a list/table of the things you know about hexagons and octagons?.Do the shapes look much the same? (Global appearance).What strategies can you use to get started?. Emphasise that for now you want ākonga to say how they would solve the problem, not to actually solve it. What do you already know about hexagons and octagons?ĭiscuss ideas about how to solve the problem.What will an answer to the problem look like?.What do you think the problem is about?.A few examples of shapes are circles, squares, rectangle, triangles, and so on. Each shape has a name depending upon the structure. Shapes are defined by a boundary which is made by combining the curves, points, and line segments. Allow ākonga time to read it and discuss in pairs or small groups. Shapes define the boundary of an object and can be differentiated in many ways based on their properties. The following prompts illustrate how this activity can be structured around the phases of the Mathematics Investigation Cycle. Note to teacher: This activity assumes the students are supplied with regular hexagons and regular octagons of similar width and area. Jess thinks that since hexagons and octagons look the same, they should have the same name.įind as many ways as you can to show Jess that they are different.
