Division on a Number Line

Mr. Squeaks is trying to get a closer look at the half moon using his plane. There's just one problem(...)he can't take off from the runway safely because it is too dark! It looks like Mr. Squeaks has an idea... he wants to use the fireflies to light up the runway! Before he can do that, he needs to come up with a plan so the lights are divided evenly along the runway. We will help Mr. Squeaks divide pairs of lights evenly using [title] "Division on a Number Line". The runway is twelve feet long and Mr. Squeaks would like to place a pair of lights every six feet. He wants to use a NUMBER LINE the same length as the runway to help him. First, we will be calculating TWELVE divided by SIX. Before we start, let's review the parts of a division problem. The DIVIDEND is the number being divided, in this case the number twelve. The DIVISOR, or the number we are dividing by, is six. The QUOTIENT will be the answer. To find the quotient using a number line we can follow three easy steps. First, circle the DIVIDEND on the number line(...)here the DIVIDEND is the number TWELVE. Second, skip count up the number line by the DIVISOR or SIX to the DIVIDEND. [enthusiastic] Let's skip count by six together! six (...) twelve! The third step is to count the number of skips to get the quotient(...)let's count them together! one (...) two (...) twelve divided by six equals two. [goes back to Mr. Squeaks] Mr. Squeaks places two pairs of lights along the runway. [worried] Oh no, it's not bright enough! Let's help Mr. Squeaks place a pair of lights every four feet. That means we will solve TWELVE divided by FOUR. First, circle the DIVIDEND on the number line(...) in this case the number TWELVE. What is the second step? (...) Skip count up the number line by the DIVISOR or FOUR to TWELVE. Let's skip count together! four (...) eight (...) twelve! What is the number of skips? (...) The number of skips is three, (...) so twelve divided by four equals three. Let's see if that's enough light for the runway now. [disappointed] It's better, but still not safe enough. Mr. Squeaks thinks if we put a pair of lights every two feet, he will finally be able to fly(...) let's help him calculate to see if he's right! What is the first step? (...) First, circle the the number TWELVE. What is the second step? (...) Second, skip count up the number line by TWO to TWELVE. This time, let's skip count on your own to see if you can find the quotient. (...) When you skip count by TWO up the number line (...) twelve divided by two equals six... which means Mr. Squeaks has six pairs of lights along the runway now. Remember, (...) to find the quotient using a number line you can follow three easy steps. The first step is to circle the DIVIDEND on the number line. The second step is to skip count up the number line by the DIVISOR to the DIVIDEND. The third step is to count the number of skips to get the quotient. Let's check in with Mr. Squeaks to see if he has enough light for the runway now! [Mr. Squeaks:] Weeeee! I think Mr. Squeaks forgot something...
