“The Tile Game is a beautiful and popular material in the Elementary class, lending itself to intricate tessellations, mosaics, calculations of area and all else that the imaginative mind of the child dictates.
I was reluctant to present Abhimanyu with the Tile Game. The domineering teacher in me reasoned that he ought to pay for his indolence. I slyly omitted him from the list of children invited for the lesson. But he was there, totally absorbed.
Abhimanyu travels light and sly omissions don’t weigh him down.
The next day I saw him make an exquisite pattern with the tile game.
I wish I could have simply stood back and admired it, but the stubborn teacher in me didn’t give up. Dripping with mockery I challenged him to find the area of the “beautiful pattern.” I couldn’t wait to see his regret and guilt, his surrender to rigour.
I expected him to –
– Count the number of triangles, parallelograms, trapeziums and hexagons
Triangles = 66
Parallelograms = 36
Trapeziums = 24
Hexagons = 13
– Find the area of each of those shapes applying the formula
Triangle – ½ x 2.5 x 2 = 2.5 sq cm
Parallelograms = 2.5 x 2 = 5 sq cm
Trapeziums = ½ x (2.5 + 5) x 2 = 7.5 sq cm
Hexagons = ½ x 15 x 2 = 15 sq cm
– Multiply it by their number
Area of triangles – 2.5 x 66 = 165 sq cm
Area of Parallelograms = 5 x 36 = 180 sq cm
Area of Trapeziums = 7.5 x 24 = 180 sq cm
Area of Hexagons = 15 x 13 = 195 sq cm
– Sum it all up together.
Total area = 165 + 180 + 180 + 195 = 720 sq cm
And he didn’t know how. Ha!
In less than ten minutes Abhimanyu had the area of his beautiful pattern. He had converted his parallelograms, trapeziums and hexagons into triangles.
66 + 72 + 72 + 78 = 288 triangles
All triangles became rectangles and the rectangle was a familiar friend!
½ x 2.5 x 2 = 2.5 x 288 = 720 sq cm
Abhimanyu travelled light and quick.
I doubly suffered because I was his teacher and his mother too. I moved around arduously with tons of load on my body and soul and appreciated “hard work.”
One Sunday afternoon he was out with the wind in his unkempt hair and shabby clothes and often unbrushed teeth. He came in with a big smile, hugged me saying, “Thanks Ma, for loving me only so much.” Gave me a little kiss and was off.
Abhimanyu truly travels light!”
