Math Mammoth Place Value 2 (Paperback) (ISBN-13: 9781954358706)

Math Mammoth Place Value 2 is a short worktext dealing with place value and three-digit numbers.

The first lessons present three-digit numbers using a visual model of the base-ten blocks (hundred-flats, ten-pillars, and one-cubes) and number lines. To reinforce the important concept of place value, children practice separating three-digit numbers into their different "parts" (hundreds, tens, and ones), and making numbers from these parts.

Next, we study skip-counting by tens, by twos, and fives. Then students compare and order three-digit numbers, including comparing simple number expressions.

After this, we study rounding three-digit numbers to the nearest ten and to the nearest hundred. Lastly, the book includes a lesson on reading bar graphs and pictographs, which provide a nice real-life application for using three-digit numbers.
