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.
