How can 9 x (12 + 27) be easy to work out? This 3rd grade find products using properties worksheet shows your child that the properties of multiplication are shortcuts, not just names to learn. Page one gives four products to find: 230 x 1, 9 x (12 + 27), (60 – 12) x 5 and 9 x 75. Page two is a worked key. For each product, it names the property, then writes every step down to the answer.
