Compatible Numbers for Third Grade Math

Benchmark numbers are another form of compatible numbers that third graders should know. These numbers end either in 0 or 5 and make the process of estimating much easier; for example, students can use 25 + 75 to approximate the sum of 27 + 73.

Compatible numbers

Compatible numbers are numbers that are close to the original numbers and ones that make the arithmetic easy. For example 2,752 is close to 2,800 so you might say 2,752/28 is approximately 2,800/28 = 100 or, 2,752/28 is approximately 2,750/25 = 110
