The ideas in this division lesson are taken from Division 1 ebook. Only a few examples of each problem type are shown; you should make more problems of each kind for the student.

When division is not exact and remainder
Free lesson plan from HomeschoolMath.net

If you divide 13 bananas evenly between Joe and Sally, how much does each one get? 13 ÷ 2 = ? We say that Joe and Sally both get 6 bananas and one is left over.  The leftover banana is called the remainder.  Or, if we don't want leftovers or remainders, both would get 6 1/2 bananas. 13 ÷ 2 = 6, remainder 1.

14 bananas divided between 3 people gives 4 bananas to each and 2 bananas that cannot  be divided.   14 ÷ 3 = 4, remainder 2

8 scissors divided between 5 people gives 1 scissors to each and 3 scissors that cannot be divided. 8 ÷ 5= 1, remainder 3

Example problems

1. Divide the dots so that groups have the same amount of dots and write a division sentence.

Divide evenly into 3 groups 20 ÷ 3 = __,  remainder __

Divide evenly into 4 groups 21 ÷ 4 = __, remainder __

Divide evenly into 6 groups __ ÷ 6 = __, remainder __

2.  Divide and indicate the remainders.  You can draw pictures!  Discuss with your teacher the patterns you notice.

3.  What is the method to find the remainder?  Discuss with your teacher.  Practice some more!
