Teaching and Learning Integers in Math Bits

If we reflect on the common word problems on integers that students do in grade 7, it is a little worrisome to realize that the average third or fourth grader in Primary School could solve them too. These problems, or rather exercises, involve real-world contexts such as debts and assets, elevators, depths to which a diver descends, temperatures, ages of historical figures, points won or lost in a game, and so on.
