Similar to another set of activities for Tenths and Hundredths, this is a comprehensive introduction to decimals and decimal place value to Thousandths. I’ve added more explicit practice in locating decimals on a number line and ordering decimals
These activities use the Base 10 Block 1000 Cube as the One, the 100 Square as .1, the 10 Rod as .01, and the 1 cube as .001. There is a suggestion as to how you can easily make a whole number Ten using commercially available boxes.
Decimal place value is just a continuation of the pattern (already familiar to 4th and 5th graders) in whole number place value. These activities make this explicit, with images of the Base 10 Blocks related to numbers written in decimal format, as fractions, and in words. The grouping of thousandths into hundredths, hundredths into tenths, and tenths into ones is shown. Students initially write decimals in a place value chart which names the value of each place.
There is plenty of practice in expressing numbers four ways: as decimals, fractions, in words, and as shaded regions of Base 10 Block 100 grids, with decimals less than 1.
Many pages end with a finely-scaled number line for students to locate each number on that page in order, so they keep perspective on the sequence and magnitude of these numbers.
