You have learned to divide numbers evenly. Today you will see that, sometimes when you divide, a part of the dividend might be left over.
Can you share 7 whole apples among 5 friends evenly? Explain your answer.
Answer:

Math Background
In this lesson, your student learns about remainders when using the division algorithm. Your student will rely on his skills in multiplying and dividing basic facts as well as his subtraction skills to perform these divisions.
Your student will put counters into arrays and then record his work using the division algorithm. As your student models the division using arrays, he recognizes why some are leftover and what the remainder in division means. For example, to find how many rows 23 band members would make with 4 members in each row, your student makes arrays. Your student finds that when he puts 23 counters in rows of 4, he gets 5 full rows. There will be 3 counters left over, which is not enough for another group of 4, so the remainder is 3.
Essential Question: What happens when some are left?
