Four-Digit Numbers and Place Value
Subtract 4-Digit Numbers with Regrouping
Rounding to Nearest Hundred
PDF download $3.00
Printed copy $9.15, b&w
Math Mammoth Place Value 3 covers 4-digit numbers (numbers with thousands), and adding and subtracting them. We also study rounding and estimating, which are very important skills for everyday life.
First, students learn 4-digit numbers, place value—breaking numbers such as 3,498 into thousands, hundreds, tens, and ones—and comparing 4-digit numbers. Next, they practice some mental addition and subtraction with 4-digit numbers. The lesson stresses the similarities between adding and subtracting 4- digit numbers and adding and subtracting smaller numbers. Practicing mental math also helps to build number sense.
We also study regrouping in addition and subtraction, using 4-digit numbers.
The last major topics in this chapter are rounding numbers to the nearest hundred and estimating. Students also get to do some more word problems.
The PDF version of this book is enabled for annotation. This means that if you prefer, your student can fill it in on the computer, using the typewriter and drawing tools in Adobe Reader version 9 or greater.
