Place Value and Rounding
Our first topic of math for the year will be place value. We will expand on the concepts that students were introduced in third grade and we will also work with larger numbers (up to millions). We will begin with learning how to write numbers in standard form, word form, and expanded form. We will then review how to identify the value of a digit in a number, for instance the value of the 2 in 529 is 20. After comparing numbers, we will explore the concept of rounding. Please click on any of the higlighted words to go to sites that we have used in the classroom. For a challenge try these links on expanded form, word form and value of digits. Additional practice with rounding can be found at Teach R Kids and aplusmath.com. For other practice with lots of other math related concepts visit the home page of aaamath.com.
