4.C.3: Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Describe the strategy and explain the reasoning.
In third grade students learned how to divide a two-digit number by a single digit number using many different strategies. These strategies may have been different than what you learned in school. Like multi-digit multiplication, your child will learn the algorithm to solve long division problems in a later grade. This year we will work on using place value strategies to solve larger division problems. The strategies that we use in class may seem to take longer than the way you solve division problems, but it is helping your child develop the understanding they need to better understand the algorithm later.
Although it may be tempting, please do not teach your child the algorithm. This tends to cause more confusion for the student. Offer your child the chance to teach you the strategies they use. The best way to learn something is to teach it!
We will work on four main conceptual strategies for division. See the parent letter that went home, as well as examples for each strategy.
Some of the Strategies We May Use in Class:
When searching for videos, many videos use different names for strategies we use in class. Be careful that what the name on the video matches the name we use in class.
Students can always check their work by using the inverse (opposite) operation, multiplication.
Dice or Cards
Use dice or cards to create your division problem. Then check your work using a calculator or multiplying. If you have a wrong answer, see if you can find your mistake.
