+# Next, draw this shape on the board/project this image and ask students what is the area and perimeter of this shape. If anyone is unclear, explain how the area and the perimeter can be found out

+# Ask students to calculate the area of the shaded region (8 sq. cm). Then, ask them to draw a different shape with the same area
+# Next, ask them to compare the perimeter of the shape displayed and the one they drew
+# Call out a few students whose shapes have perimeter lesser, greater and same as the one displayed and share it with the class
+# If there are no examples for any of the categories, challenge them to find suitable shapes

+=== Activity 2: Puzzle ===
+==== Materials: ====
+Print-outs of the puzzle [or] projector to display and rectangular dot sheets
+==== Objectives: ====
+==== Process: ====
+# Handover print outs of the 'Share the land' puzzle([https://ncert.nic.in/textbook.php?eemh1=11-14 NCERT Class 5 Mathematics Textbook]) to students individually or in pairs and ask them to solve it.
+# Discuss different solutions/strategies that students come up with
+=== Activity 3: Game ===
+==== Objectives: ====
+==== Materials: ====
+* dot sheets/graph sheets,
+* crayons of different colours
+* dice (2)
+==== Process: ====
+# Students are paired/ divided into groups and given the listed materials
+# Each player rolls the dice and draws a rectangle of equivalent size. Eg - if they roll 2 and 4, they draw a 2x4 rectangle.
+# The player who covers maximum area first, wins.
+# Ask students to calculate the perimeter of each rectangle they draw and of their final shape as well.
+# Reference: Conquer the area (activity 2 in https://iheartteachingelementary.com/area-and-perimeter-games/)
+=== Discussion after both activities: ===
+* Does perimeter always increase if area increases?
+* Does area always increase if perimeter increases? (If they say yes,give the initial grid examples as reference and ask them to check if it is holding true)
