Teaching Place Value to Fourth Graders
Most teachers are able to jump right into place value at the beginning of the year with their fourth graders without much review. The standard 4.NBT.2 is a deeper level of understanding (and uses much larger numbers) from the second grade NBT standards. The skills of using base ten blocks, writing numbers in different forms, and comparing numbers is much the same.
However, one of the hardest concepts to teach in fourth grade is the value of places. See the standard below.
4.NBT.1 Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right.
Standard to review before you teach 4.NBT.1:
3.NBT.3 Multiply one-digit whole numbers by multiples of 10 in the range 10-90 using strategies based on place value and properties of operations
-prepares students for understanding how numbers can increase (and decrease) ten times.
Not only is it important for students to understand multiplying by ten means ten times more and dividing by ten means ten times less, but students also need to understand the value of the digit has changed. Having a solid understanding of this in fourth grade will help prepare students for more difficult skills and concepts, such as exponents, that come in later grades.
