Learning how to compare two numbers as greater or less than is a first grade, Common Core math skill: 1.NBT.3. Below we show two videos that demonstrate this standard. Then, we provide a breakdown of the specific steps in the videos to help you teach your class.
Your students should be familiar with counting from 1 to 100 using 1’s and 10’s, starting from any number. They should also be able to read, write, and represent objects using numbers between 0 and 20 (K.CC.1-3).
Later on, understanding place values will enable your students to skip-count within 1000 (counting by 5’s, 10’s, and 100’s). They will also be able to read and write numbers by using “base ten numerals, number names, and expanded form” (2.NBT.1-3).
Common Core Standard: 1.NBT.3 - Compare 2 two-digit numbers based on meanings of the tens and ones digits
Students who understand this principle can:
2 Videos to Help You Teach Common Core Standard: 1.NBT.3
Below we provide and breakdown two videos to help you teach your students this standard.
Video 1: Comparing Race Car Numbers
In the beginning of the video, the narrator zooms in on a race car and greets the students. He tells the students that they’re going to compare the numbers on the race cars competing in the race.
He reminds the students that they already know about place value and how to compare them using base-ten blocks. As the race begins, the narrator helps students compare numbers as greater than or less than.
He explains that students can look at the number in the tens spot first to help compare the numbers.
The narrator reminds the students that it’s important to start comparing in the tens place. The video ends with all the cars zooming off, starting another race.
Video 2: Compare Numbers with our Crocodile Friend
The video begins by explaining that when comparing two numbers, we use the following signs to help us understand their relationship: >, <, and =.
After, the Crocodile comes on screen, and Boddle explains that he is always hungry. He only wants to eat big numbers.
First, he chooses between 2 and 6. Boddle asks the students if they know which number is larger. 6 is larger, and so he eats the 6.
Boddle then points out that the Crocodile’s mouth is similar to the less than sign (<), meaning that 2 is less than 6– (2 < 6).
Next, Boddle offers practice problems with larger numbers so your students can get a better grasp on how to compare two-digit numbers. Below those practice problems are shown.
Boddle congratulates students on a job well done, inviting them to come back again.
