![]() Also, students plot 7.468 and 23.15 on a number line to compare the magnitude of the numbers. The teacher asks students to compare these numbers, beginning with the greatest place value and explains that the number 23.15 has 2 tens and the number 7.468 does not have any tens so 7.468 7.468 even though both numbers have the same amount of digits. For example, when comparing 7.468 and 23.15, students record 7.468 and 23.15 in a place value chart.It is imperative for students to develop a conceptual understanding of rounding, such as what the benchmarks are, using place value understanding to round numbers without instruction of mnemonics, rhymes or songs. Instruction includes the use of place value charts, number lines and relational symbols to compare numbers to the thousandths that have the same amount of digits but different values.This type of data ranking is performed as part of many academic and statistical studies in the. That student may claim that 2.459 is greater than 13.24 because the digit 2 is greater than the digit 1 (though they are actually comparing 2 and 10). Decile: A decile is a method of splitting up a set of ranked data into 10 equally large subsections. For example, when comparing 2.459 and 13.24, a student may not consider the magnitude of the numbers and only look at their digits.Students may be confused when comparing numbers that have the same digits (but different values).Instruction expects students to justify their arguments when plotting, comparing and ordering ( MTR.4.1).Students should use place value understanding to make comparisons. >,, and < symbols to record the results of comparisons. During instruction, teachers should show students how to represent these decimals on scaled number lines. Compare two decimals to thousandths based on meanings of the digits in each place, using.During instruction, students should apply understanding of flexible representations from MA.5.NSO.1.3 to help them reason while plotting, ordering and comparing.In grade 4 ( MA.4.NSO.1.5), decimals were plotted to the hundredths, and in grade 6 ( MA.6.NSO.1.1) rational numbers, including negative numbers, will be plotted. Purpose and Instructional StrategiesThe purpose of this benchmark is for students to use place value understanding to plot, order and compare multi-digit numbers with decimals to the thousandths. Benchmark Numbers: Everyone Can DO Fractions, Decimals and Percents. ![]() Connecting Benchmarks/Horizontal Alignment
