We are continuing our decimal unit by learning how to divide decimals by whole numbers and other decimals. Students were very proficient with dividing by whole numbers so we moved right into dividing decimals by other decimals. Here are the steps students copied from our board today in class:
Step 1: Ask yourself, “Is the divisor a whole number?”
Step 2: If the divisor is NOT a whole number (if it has a decimal in it), move the decimal enough times to the right to make it a whole number.
Step 3: Move the decimal the SAME number of places to the right in the dividend.
Step 4: Bring the decimal up to the quotient line.
Step 5: Divide
We worked many examples together during class and most students seemed to understand the skill. The examples we worked together are actually various problems from their homework! Students…please make sure to show your work so we can check for accuracy tomorrow as we grade this homework.
