Comparing large numbers as greater than, less than, and equal to is a second grade Common Core math skill: 2.NBT.4. 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 the first grade skill of counting up to 120 starting from any number below 120 (1.NBT.1), this skill helps them understand greater or less than values. The second grade skill is also closely linked to the first grade skill of understanding place values (ones and tens) in two-digit numbers (1.NBT.2).
Comparing large numbers as greater than, less than, and equal to will help your students understand future concepts in third grade. In third grade, your students will learn how to interpret the products of whole numbers (i.e. 8 x 3 is the same as 8 groups of 3 objects each) (3.OA.1). They will also learn to use multiplication and division within 100 while solving word problems in situations that involve “equal groups, arrays, and measurement quantities” (3.OA.3).
Common Core Standard: 2.NBT.4 - Compare two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons
Students who understand this principle can:
2 Videos to Help You Teach Common Core Standard: 2.NBT.4
Below we provide and breakdown two videos to help you teach your students this standard.
Video 1: Comparing Two Large Numbers with Active Participation
The video presents 4 pairs of numbers and asks the viewer to identify which number is greater. This video is a great way to get your students actively involved in answering the problems.
After the video goes over the anser, you can have your students do the letter pose on the greater side for 10 seconds. If the numbers are equal, they can do both poses for 10 seconds.
Video 2: Comparing Numbers Up To 1,000
The video begins by stating the best way to compare large numbers is by comparing each place value, starting from the leftmost digit. Two examples follow demonstrating this concept.
Next, the video practices what your students have learned by comparing more numbers. Boddle asks your students to fill in the blank with greater than (>), less than (<), and equal (=).
