+*Estimated Time : 40 minutes.
+*Materials/ Resources needed: Chart papers, scissors, pencil, scale.
+*Prerequisites/Instructions, if any
+# The students should have understanding of basic shapes like square, rectangle, parallelogram, triangle and trapezium.
+# They should be able to draw mentioned shapes accurately and cut exactly on boundaries.
+*Multimedia resources
+*Website interactives/ links/ / Geogebra Applets
+*Process:
+# This is a very old Chinese puzzle known as a tangram.
+# Cut out the square below into 7 shapes.
+# Cut out the 7 shapes and rearrange them to form:
+(a) a square from two triangles, and then change it to a parallelogram;
+(b) a rectangle using three pieces, and then change it into a parallelogram;
+(c) a trapezium with three pieces;
+(d) a parallelogram with four pieces;
+(e) a trapezium from the square, parallelogram and the two small triangles;
+(f) a triangle with three pieces;
+(g) a rectangle with all seven pieces.
+# Finally, put the pieces back together to form the original square.
+*Developmental Questions:
+# Were you all able to read and follow the instructions.
+# Name and point the different shapes in the figure.
+# Name the dimensions of each shape.
+*Evaluation:
+# Analyse how much space each shape is occupying.
+# What can you refer to the space occupied by each shape.
+*Question Corner:
+# What are the characteristic properties of each shape: square, rectangle, triangle, parallelogram and trapezium ?
+# What type of two triangles would you need to form a square ?
+# What did you learn from this activity ?
