*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 ?
