If you gave the calculator less than "A", please help me improve the calculator by telling me what I would need to do for it to earn an "A". Please provide numbers separated by commas to calculate the standard deviation, variance, mean, sum, and margin of error. Once children are confident with their long division questions, reasoning activities can then be introduced, such as long division with missing digits, or spot the mistake/s, moving on ultimately to worded long division problems. using the standard division algorithm (not a calculator!) Most values cluster around a central region, with values tapering off as they go further away from the center. The partial quotients method for long division with two-digit numbers is set out in the first two columns below; it encourages children to think about the relationship between multiplication and division by estimating first how many times the divisor is likely to go into the dividend. Division can be thought of as the number of times a given number goes into another number. For more information and examples using the Euclidean Algorithm see our GCF Calculator and the section on The scaffold method is a visual method that helps break down the numbers in a way that some of your students may understand more fully than the normal method of long division.
