\nDescribe a pattern you notice<\/p>\n
\nIdentify the property shown by the pattern in the multiplication table.
\n(1 \u00d7 3) + (1 \u00d7 5) = 1 \u00d7 (3 + 5)
\n(2 \u00d7 3) + (2 \u00d7 5) = 2 \u00d7 (3 + 5)
\n(3 \u00d7 3) + (3 \u00d7 5) = 3 \u00d7 (3 + 5)
\nDescribe the pattern in your own words.
\n![\"Big](\"https:\/\/ccssmathanswers.com\/wp-content\/uploads\/2020\/12\/Big-Ideas-Math-Answer-Key-Grade-3-Chapter-5-Patterns-and-Fluency-5.1-2.png\")
\nWhat property does the pattern show?
\nAnswer:
\nIt shows the Distributive property. The distributive property tells us how to solve expressions in the form of a(b + c). \u00a0The distributive property is sometimes called the distributive law of multiplication and division.
\nDistributive property => a(b+c)=ab+ac.<\/p>\n
\nShow how the Distributive Property works for other columns above.
\nAnswer: As per distributive property. b and c are presented on column.It is represented in above figure clearly.<\/p>\n
\nDescribe the pattern shown by the shaded products in the multiplication table.

\nLook at the factors of the shaded products that are the same. What do you notice?
\nWhat property explains this pattern?
\nShade a different diagonal in the table that shows a similar pattern as the shaded products
\nAnswer:
\nIt shows the products are same (a x b) = (b x a) equations. whatever may be the order but multiplication of of any two numbers will always be the same in vice versa.
\nThis is a commutative property.
\nThe\u00a0commutative property\u00a0states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The\u00a0property\u00a0holds for Addition and Multiplication, but not for subtraction and division.

\nShade the rows for 2, 4, 6, 8, and 10 one color. Describe the pattern in the products.
\nAnswer:
\nThe products end in 0, 2, 4, 6, and 8; the products are even.

\nCompare the rows for 2 and 4. Describe the pattern in the products.
\nAnswer:
\nThe products of 4 are the products of 2 doubled.<\/p>\n
\nShade the rows for 1, 3, 5, 7, and 9 another color. Describe the pattern in the products. What do you notice about the products and their factors?
\nAnswer:
\nThe products repeat\u2013even, odd.

\nAnswer:
\nNo, It cannot be.
\nExplanation:
\nAn odd\u00a0times\u00a0even\u00a0is always\u00a0even.It means when an even number is multiplied by odd number product will be even.<\/p>\n
\nDIG DEEPER!<\/strong>
\nDoes the multiplication table above have more even products or more odd products? Explain.
\nAnswer:
\nSometimes there are even numbers next to each other in the table. However, there are never odd numbers next to each other.

\nA different type of bamboo grows two times as fast. Explain how you can use the multiplication table to\ufb01nd how many inches this bamboo will grow in 8 days
\nAnswer:
\nBamboo tree growth is 2 times faster than old bamboo tree so, 2 days growth is 2 x 3 = 6 inches.
\nBamboo tree growth after 8 days = 8 x 6 =48 inches.

\nLook at the shaded products. Describe the pattern.
\nLook at the factors of the shaded products that are the same. What do you notice?
\nWhat property explains this pattern?
\nWhat do you notice about the factors of the shaded product that does not repeat? Explain why you think this happens.
\nShade a different diagonal in the table that shows a similar pattern as the shaded products.
\nAnswer:
\nIt shows the products are same (a x b) = (b x a) equations. whatever may be the order but multiplication of of any two numbers will always be the same in vice versa.

\nIf she continues togain the same number of pounds each week, how much will she weigh after 7 weeks?
\nAnother puppy gains 6 pounds in 2 weeks and 12 pounds in 4 weeks. How many pounds does he gain each week?
\nAnswer:
\nAs per table for 2 weeks it gains 4 pounds then one week it gains 2 pounds.
\nIt is clear that each week it gains = 2 pounds.
\nAfter 7 weeks it gains = 7 x 2 =14 pounds.<\/p>\n
