## Why is it important to use a place value chart?

A place value chart is an excellent tool for helping students make sense of large numbers. Place value is a foundational math concept, necessary for addition, subtraction, exponents, long division, fractions and almost every other math operation.

During second grade, your child is introduced to the concept of using “place value” (the value of where the digit is in the number, based on the location of the digit) in order to add and subtract numbers. … This strategy helps her think abstractly about what she is doing while building her number-sense at the same time.

## How do you divide numbers?

Divide whole numbers

Multiply the quotient by the divisor and write the product under the dividend. Subtract that product from the dividend. Bring down the next digit of the dividend. Repeat from Step 1 until there are no more digits in the dividend to bring down.

## How do you divide unequal fractions?

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.
