Student will use tactile graphics to compute area of given shapes and create scale replicas.
-
Basic knowledge of properties of specific shapes
-
Basic understanding of area
-
Give student tactile shape.
-
Using the squares on the graph paper, have the student calculate area.
-
Discuss “scale” and give tactile examples of various shapes (not only geometric shapes).
-
Have the student use graphic art tape to create a scale replica of the original shape.
-
Use the squares to calculate the area of the new shape.
-
Compare areas of the shapes in relation to scale.
-
Have tactile shapes created beforehand that they will be reproduced in different scale.
