−*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 ?
