Let’s watch a video about adding with a number line!
Watch the video below to learn how to use the number line to help you add numbers.
Hello! I am so glad you made it to my diner. You are going to help me serve the food and add up the totals for the bills. Let’s go!
Please take these plates to table number 1. Then let’s go to our Diner Number Line to add them up.
Always start with the biggest number on number line.
Now jump forward the number of times of the addend. We’re adding 9 to 15 so we will jump 9 times. Count with me!
1…2…3…4…5…6…7…8…9. What number did we land on? Great! Let’s write the bill.
$15 plus $9 equals $24. The next order is up, let’s take them to the tables.
These plates go to Table 2.
Put your finger on which number you should start with on the number line.
Yes, always start with the greatest number. How many times will we jump forward? What number is the other addend?
You got it! Put your finger on number 13 and let’s jump 8 times.
1…2…3…4…5…6…7…8. What number did we land on? Terrific! Let’s write up the bill.
$13 plus $8 equals $21.
Table 3’s food is ready. Let’s serve them!
Look at the price tags. Which number should we start with on the number line?
Right! 23 is the greater number. How many times will we jump forward?
Correct. We will start with 23 and jump 11 times. Count out loud with me.
1…2…3…4…5…6…7…8…9…10…11. What number did we land on? You got it! Let’s write the bill.
$23 plus $11 equals $34.
Thanks! I’m so glad you came to help at the diner today! Remember to always dine with a number line! Good-bye!
