Math Mammoth Place Value 3 is a short worktext meant for third grade level. It focuses on place value with four-digit numbers, and adding and subtracting such numbers. We also study rounding and estimating, which are very important skills for everyday life.
First, students study place value with four-digit numbers, writing four-digit numbers in expanded form, and comparing.
Next, they practice some mental addition and subtraction. The lesson stresses the similarities between adding and subtracting four-digit numbers and adding and subtracting smaller numbers. Practicing mental math also helps to build number sense.
After that we study regrouping in addition and subtraction, using four-digit numbers. The last major topics in this book are rounding numbers to the nearest hundred and estimating. Students also get to do some more word problems.
The answers are appended.
