Process (How to do the activity)



 * 1) There are 6 regions in the above venn diagram.
 * 2) The teacher can ease the activity by having an initial round of oral discussion in the previous classes such as every parallelogram is a rectangle if and only if it has ........
 * 3) Every quadrilateral is a kite if it has .........
 * 4) Rectangles, squares and rhombus are all .........
 * 5) A square is a special type of ..............
 * 6) When the students are fairly comfortable, the teacher can ask the students to group the different types of quadrilaterals in the approprriate places of the venn diagram as per their properties.
 * 7) After all the groups complete the activity the teacher can ask them to present on the black board and clarify.
 * Developmental Questions:
 * 1) Ask the students to discuss properties among the group and do the venn diagram.
 * Evaluation:
 * 1) Name the universal set here.
 * 2) Name all the subsets.
 * Question Corner
 * 1) Draw a flow chart of types of quadrilaterals.
