Basics on the topic Adding Using Chart

The hundreds chart is an incredible tool to help solve problems, see patterns, or even just count! The hundreds chart is organized with numbers one through one hundred in columns and rows. How do you add using a chart?

  • Always start by circling the bigger addend, or number on the chart.

  • Next, count on the amount of the second addend or number.

  • Finally, the number that you land on is the sum, or answer.

Transcript Adding Using Chart

: "I can't believe we've become captured as PETS!" : "Maybe we can use your beam to get us out." Imani has found some things in the cage to create a portal using their beam. Hang on, what's this? There's an equation on the door! : "I guess we need to solve it to make the door open." Mr. Squeaks and Imani can use "Adding Using a Chart" to help them open the doors. There are many different tools and strategies to help add. Today we will use the hundreds chart, an incredible tool to help solve problems, see patterns, or even just count! The hundreds chart is organized with numbers one through one hundred in columns and rows. Remember when you read a hundreds chart you read it like a book, from left to right. The equation Mr. Squeaks and Imani need to solve first is fifteen plus six. When using the hundreds chart to solve addition problems, start by circling the bigger addend, or number on the chart. What's the bigger addend here? Fifteen. Next, count on the amount of the second addend. We need to count on six more to find the answer (...) count with me! One (...) two (...) three (...) four (...) five (...) SIX! Finally, the number you land on, twenty-one, is the sum, or answer! : "No! We're in the cage again!" : "And it looks like we need to solve another equation before we can teleport again." Mr. Squeaks and Imani can use adding with a chart to get the portal open again! Their next equation is twenty-three plus seven. Remember to start by circling the bigger addend or number on the chart. Next, we can count on the amount of the second addend, so we need to count up seven more. Count with me! One (...) two (...) three (...) four (...) five (...) six (...) SEVEN! Finally, the number that you land on is the sum, or answer. What is the sum here? The sum is thirty! So, twenty-three plus seven is thirty. : [eyes are closed and he's scared/frustrated] "Please tell me we're back home...oh rats!" : "One more time for good luck?" Mr. Squeaks and Imani are going to solve one more equation to try to get home. If their equation is thirty-one plus eight (...) what should they do first? First they should circle their bigger addend on the hundreds chart, thirty-one. Next, they need to count up eight, let's help them count! One (...) two (...) three (...) four (...) five (...) six (...) seven (...) EIGHT! Finally, the number that they land on is the sum, or answer. What is the sum of thirty-one plus eight? (...) Thirty-nine! Before we see if Mr. Squeaks and Imani have finally made it home, let's review. Today we learned about adding using a chart. Remember, when adding using a hundreds chart... Always start by circling the bigger addend, or number on the chart. Next, count on the amount of the second addend or number. Finally, the number that you land on is the sum, or answer. Now, let's see if they finally made it home. : "I slept so well last night, what about you Imani?" : "Wait a second, I'm in my bed? At home?" Mr. Squeaks]: "Was it all just a dream?"
