Understanding and identifying place values like ones, tens, hundreds, and thousands is a second grade, Common Core skill: 2.NBT.1. 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.1 - Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones
Students who understand this principle can:
2 Videos to Help You Teach Common Core Standard: 2.NBT.1
Below we provide and breakdown two videos to help you teach your students this standard.
Video 1: Place Values in Three Forms
The video explains what place values are, including ones, tens, hundreds, and thousands. It then demonstrates three different forms your students can use to represent place values.
The video begins by drawing four dashes in a row, and then labels the dashes as ones, tens, hundreds, and thousands from right to left.
After, the video talks about the different forms, starting with Standard form, then Expanded form, and then Word form.
Video 2: Place Value Practice with Blocks and Numbers
This video begins by reviewing place values, explaining that each digit in a number has a title, depending on where it is positioned.
Next, Boddle uses a visual example to demonstrate the concept using blocks. You can use blocks with your students to help them understand place value.
The second half of the video provides additional practice for understanding place value. Boddle presents a number and asks your students to identify the place value of the underlined digit.
