1 Introduce Shapes
You can find 3 dimensional shapes all around us, we group shapes together according to properties we can identify, like; faces, edges, vertices. Have students identify the different attributes they can find in the real life models of the shapes. Use manipulatives and real life examples (cereal boxes, candles, etc..)
Look at all the different shapes, what do you notice about them? How are they similar? How are they different?
Teach the students the vocabulary needed to identify and discuss shapes, create a math word wall in you class and use the very fun Flocabulary website to teach the vocab to your class
Mathematicians use math vocabulary so that everyone knows what they are talking about. Learn the correct language for identifying shapes.
3 Practice with Nets
Have students create digital 3-D nets of the shapes. In this app they can explore the different features of the shapes. Have students choose 2 nets they want to print and build. Students can also create a chart recording the different shapes and features
Build the shapes in the app. Choose 2 of your favourite to print and build in real life.
4 Real Life examples
Have students take pictures of real life examples of assigned shapes. Using the skitch app, they can draw right on the pictures to identify the various features of the shapes you've been studying. This can also be used an assessment step to determine if students understand the concepts presented
Print nets from the app and see if students can identify the shape they will create.
Key Standards Supported
|2.G: Reason With Shapes And Their Attributes.|
|2.G.1||Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces.5 Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.|
|2.G.2||Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.|
|2.G.3||Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.|
|3.G: Reason With Shapes And Their Attributes.|
|3.G.1||Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.|
