This fun math activity has fun multiplication and division problems that 3rd graders have to do mentally.

For example, in the problem 43,879/2,847, if you round the dividend up to 44,000 and the divisor up to 3,000, you can estimate that the solution should be close to 15 as 3 x 15 = 45. Examine the divisor, simplify it and check for multiples that are close to the value of the dividend.
In the example, 74,833/77, there are two options: if you round the divisor up to 80, your estimate of 9 will be based on 8 x 9 = 72 and rounding down to 70, your estimate of 10 will be based on 7 x 10 = 70.
The actual quotient is 971.86, so either estimate is useful.
Jacob Nomi has been writing professionally since 2011.They will also be using their subtraction skills extensively to solve division problems.Practicing division problems is the best way to improve kids’ speed and accuracy in solving division problems.We have a selection of long division worksheets here with ready to fill in boxes and several difficulty levels, so that students can gradually master the 'science of the dreaded long division'.Our first section of tail division worksheet are based on dividing 2 digits by 1 digit.So it's time to master the long division concept by grade level 5.Some of our long division material is set up in such that the math learner has to find the divisor, or dividend given the quotient outcome.We feel that long division should not be a problem for math students and if it is, the whole concept of division needs to be retaught (and learned).Division (and multiplication) are arguably the most important components of the skill set needed for secondary level math, algebra and statistics.Once you've gotten an idea of where to start, arriving at the final quotient is relatively simple.Round the divisor and dividend up or down to make challenging problems more manageable.
