An activity was conducted for students at OIS on
Addition properties of rational numbers. Students were divided into four groups
and without revealing the name of the property, they were asked to evaluate the
following by taking A and B as different Rational numbers.
1) A+B and B+A
2) (A+B) +C,
A+ (B+C) and (A+C) +B
3) A+0 and
0+A
4) A + (-A)
and (-A) + A
All the four groups explained their inferences and understood
all the properties of addition of Rational numbers. It was an effective
learning practice for children.
