Use Strategies and Properties to Divide by 1-Digit Numbers

In this topic, students will:

• use mental math and place value to divide multiples of 10 and 100 by 1-digit divisors

• use compatible numbers to estimate quotients

• use place-value patterns and division facts to estimate quotients for 4-digit dividends 

• solve division problems and interpret remainders

• use partial quotients to divide

• use partial quotients and place-value understandings to divide with greater dividends

• use place value and models to divide 2- and 3-digit numbers by 1-digit numbers

• choose a strategy to divide that follows a series of steps to break division into simpler calculations

Vocabulary:

Remainder - a number that remains after the division is complete

Partial quotients - a way to divide that find quotients until only a reminder, if any, is left

Dividend - the number to be divided

Divisor - the number by which another number is divided

Quotient - the answer to a division problem

At-home Practice:

Supplies:

• a deck of cards (remove all face cards)

Divide the deck evenly between players. Each player flips over 2 cards. The first player to identify a division fact with the cards wins all the cards (ex. Players flip over 10, 5, 2, and 3. Player 1 identifies the division fact 10 divided by 5 equals 2.) If no player identifies a division fact, all players turn over new cards. Continue playing until 1 player has all the cards.
