The Distributive Property Day 2
3
So yesterday we learned about partial products. Those are when you split up a two digit number into ones and tens, multiply, and then add the products together. The distributive property allows you to multiply a sum by a number. The distributive property and partial products work together! Let’s look back

So today, we’re going to use the distributive property to solve problems like we did yesterday! For a field trip, 42 students each paid $3 for bus transportation. How much money was spent in all for bus transportation? My problem would look like this: 3 x ( 40 + 2) This is what we did yesterday. Break up 42 into tens and ones.
5
Now how will we solve it? 3X ( 40 + 2 ) We are going to distribute the 3 to both numbers in the parenthesis. Do this with me in your notebook! ( 3 X 40 ) + ( 3 x 2 ) Now multiply what is in each parenthesis. ( 3 X 40 ) + ( 3 x 2 ) 120 6 + =126

So then the answer to the problem: For a field trip, 42 students each paid $3 for bus transportation. How much money was spent in all for bus transportation? $126 was the total collected for the bus transportation!

Let’s try another. Find the product of 7 x 26 using the distributive property. 7 x 26 =7 x (20 + 6 ) Start by breaking up the 26 Now let’s distribute the 7 to both of the numbers in the parenthesis. = ( 7 x 20 ) + ( 7 x 6 ) Now multiply each set. = 140 + 42 = 182 Add the partial products!

Try some on your own! 6X 13 = 12X 8 = 19 X 9 = I want to see work in your notebook!

TT he distributive property lets us multiply a sum by a number WW e need to make sure that we are distributing the number outside the parenthesis to both numbers in the parenthesis MM ake sure to add your partial products at the end! Let’s RE-

BONUS!!! Here is a bonus question. If you would like, you may try it. If you attempt the problem, you will receive a prize. If you attempt AND get the problem correct, you will receive a double prize! Use the distributive property to solve: 9 x 874 = Good luck!
