Essential Understandings
Concrete:
- Identify place value to the tenths, hundredths and thousandths place.
- Use a number line to determine which number is closer to the given value (i.e., given 30.433, place the number on the number line between 30.43 and 30.44. Use the distance between the numbers, to determine that 30.433 is closer to 30.43 than it is to 30.44).
- Understand the following concepts, symbols, and vocabulary: place value, ones, decimal, tenths, hundredths, thousandths.
- Apply the rule for rounding (e.g., find number on a number line—if five or greater, round up, if less than five, round down).
- Identify the nearest tenth, nearest hundredth.

Cluster:
Know that there are numbers that are not rational, and approximate them by rational numbers. (Supporting Cluster) : Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters. |
