1. Take another look at the properties of multiplication that you have studied. Now complete the following:
17 x (15 x 13) = (_________________________x 15) x 13
(246 x 38) x 19 = 246 x (_____________x _____________)
_______________________ x (526 x 59) = (63 x 59) x 526
(349 x _______________________) x 68 = 72 x (349 x 68)
SOMETHING MORE TO KNOW!
The DISTRIBUTIVE PROPERTY of multiplication makes it much easier to calculate the product.
Calculate the answer to the following:
(7 + 3) x 5 = _________________________________
(7 x 5) + (3 x 5) = _____________ + _____________ = _____________
Thus: (7 + 3) x 5 = (7 x 5) + (3 x 5)
2. Work together with a friend and fill in the missing answers:
a) 68 x 27 = 68 x (_______________ + _________________)
b) 94 x 536 = 94 x (_______________ + _____________ + 6)
= (94 x _______________) + (94 x _______________) + (_______________x 6)

Learning Outcome 1: The learner will be able to recognise, describe and represent numbers and their relationships, and to count, estimate, calculate and check with competence and confidence in solving problems.
Assessment Standard 1.12: We know this when the learner recognises, describes and uses:
1.12.2: the commutative, associative and distributive properties with whole numbers.
