This is the third in the series of explorations of the properties of addition and multiplication with different number sets. After considering the set of (i) Whole numbers and (ii) Non-negative rational numbers 1 , in this article we will deal with the integers. This is a good time to reflect on the series − its need and aspiration.

In our last Low Floor High Ceiling article, we had looked at Squaring the Dots... a series of questions on counting the dots inside squares of different sizes and orientations drawn on dotted paper with the dots as lattice points. The focus of the activity was to tilt squares and try to find a general formula for the number of dots inside the square of a particular tilt, as the side of the square changed.

I write this to tell myself that it was not a dream...

This year I taught a bunch of fifth standard kids in Sahyadri School KFI (Krishnamurti Foundation India), who, like all others of their age, were high-energy kids; they were willing to explore but found it difficult to sit down in one place. I had a great relationship with them. The air in the classroom was of love, trust and wonder!

Materials can be important for helping children learn. The very young child learns in interaction with and acting on the objects around her. In the beginning, the senses, motor abilities and subsequent causal analysis develops through their observations of the things around and their behaviour in different circumstances. This interaction with materials is spontaneous and directed by the child. The manner of interaction is decided by her and often their explorations do not meet with the approval of the adults.

The interesting nature of magnets attracts everyone, from playing with magnets for fun to using appliances with magnets, we find them everywhere around us.

Insects are everywhere in our life. Often we ignore them either because they are too small or too common. Through this series of activities we focus on children's observation skill and guide them to find out common insect's role & function in our surroundings. Children can understand all insects are neither harmful nor do they disturb us and many insects are helpful for us especially in organic farming / gardening.

It is said that India has about 2,500 species of fish which are 11.7% of fish species in the world. Among India, as Bengal is called ‘the land of Maach (fish) & Bhaat (rice)’, fish is very popular diet in West Bengal. Diversities of water bodies existing in the landscape of West Bengal offers wider variety of fishes too.

The lesson plan is for class 6th, Science Chapter - Getting to know Plants.
