Such a numbers a and b called product preserving pair. For example, in this games the teacher would have to write two pair of PP numbers. Preserving product e. g. 10×40= 20×20 And ask student to find the rule and find the others pair. ii) Preserving Product and Altering the Place Value (PPAP) Games ljBfno txdf lgd {f0fjfbL ljlwjf6 ul0ft l;sfpg pkof ] uL x'G5 . o;sf ] v] nsf ] lgod o;k|sf / 5 . e. g. 12 x 84 = 21 × 48 And ask student to find the rule and find the other pairs. The rule is: (10a + b) x (10 c + d) = (10b + a )x (10d + c) where a, b, c, d are non-zero one digit whole numbers and c is obtained by multiplying b by some real number and d is obtained by multiplying the same real number.
