Rounding to the Nearest Ten and Hundred
... Topic C builds on students’ Grade 2 work with comparing numbers according to the value of digits in the hundreds, tens, and ones places (2.NBT.4). Lesson 12 formally introduces rounding two-digit numbers to the nearest ten. Rounding to the leftmost unit usually presents the least challenging type of ...

... The numbers {1, 2, 3, 4, 5, 6, …} are called natural numbers or counting numbers. A natural number is even if it is divisible by two with no remainder. Otherwise the natural number is odd. The whole numbers include the natural numbers and zero. If one natural number divides evenly into another, ...

... A. Front-End: The front-end method uses the leftmost digits only and covers up all the other digits. For example, in a multiplication problem, 37 x 55, students consider just the 3, 30 and the 5, times 50, which would be 1500. B. Rounding: Rounding changes the numbers in the problem to others that a ...

... A notable feature of the above calculation is the systematic (though implicit) way in which insignificant quantities are discarded or “zeroed”, through rounding. The “general” rule for rounding was rounding to the nearest integer, so that a quantity greater than 12 was rounded up to the next higher ...

... Compatible Numbers: Numbers that add up to values that are easy to compute with mentally, like 10 or 100. Example: 4 & 6, 7 & 3, and 8 &2 are pairs of compatible numbers because they add up to 10. Compensation: Adjust one number to make the calculation easier and then make up for that change after t ...

Estimate Sums
... You can use rounding to estimate sums. Round to estimate the sum of 477 + 592. Step 1 Round each addend to the nearest hundred. 477 rounds to 500. 592 rounds to 600. Step 2 Add the rounded numbers. 500 + 600 = 1,100 Step 3 You can get a closer estimate by rounding to a lesser place value. Rounding t ...
