Dividing by ZERO does not make sense. Think about these:
If there are zero people, then there is no sense in talking how many
bananas they might get. |
1. Do the divisions but cross out all the problems that are impossible. You can think about dividing bananas between certain number of people to help you.
|
4 ÷ 1 = 4 ÷ 0 = 0 ÷ 1 = 0 ÷ 4 = |
14 ÷ 14 = 14 ÷ 0 = 0 ÷ 14 = 14 ÷ 1 = |
0 ÷ 5 = 10 ÷ 10 = 10 ÷ 0 = 10 ÷ 1 = |
2. Remember how zero and one work in multiplication?
|
Multiplication is REPEATED ADDITION:
Therefore,

3. For each division, make a multiplication sentence if possible. Some
divisions are not possible!
|
6 ÷ 1 = __ ÷ __ = |
42 ÷ 7 = __ ÷ __ = |
0 ÷ 7 = __ ÷ __ = |
|
81 ÷ 9 = __ ÷ __ = |
0 ÷ 0 = __ ÷ __ = |
6 ÷ 6 = __ ÷ __ = |
4. For each multiplication, make a division sentence if possible.
Some divisions are not possible!
|
6 × 1 = __ __ ÷ __ = __ |
0 × 8 = __ __ ÷ __ = __ |
6 × 8 = __ __ ÷ __ = __ |
||
|
10 × 11 = __ __ ÷ __ = __ |
1 × 1 = __ __ ÷ __ = __ |
9 × 0 = __ __ ÷ __ = __ |
5. Write a division OR multiplication sentence for each word problem.
| a) Grandma's chickens laid one day 60
eggs. She
divided them into 12-egg cartons. How many cartons did she get?
|
b) Each mini-van taxi can hold 7 passengers and there are 6 taxis waiting on the airport. How many passengers can they take?
|
| i) Six children earned 36 dollars by doing
yard work together. They divide the money equally. How much does each one get?
|
j). Kathy needs to read a 27-page booklet. She plans to finish it in three days. If she reads the same amount each day, how many pages will she read each day? What happens if she instead plans to finish it within a week? |
6. Fill the multiplication facts from the table of 7 and a corresponding division fact for each. Do the same for table of 6.
|
|
(and if you have forgotten ANY other multiplication table, do this same exercise
for that table.)

P.S. ....
| Check out these short video clips from my favorite band - Rockabilly.US. They play oldies, Elvis, country, and top hits of the 50s and 60s. It's a show with large band, costumes, choreography, little skits, "Kid Kritters", 6 dancing/singing girls, junior dancer troupe, etc. | |
|
"Be My Baby" originally by the Ronettes |
Impossible Dream (Elvis song) |
| Most importantly, the band wants to use the uplifting and energetic music to bring some fun, happiness and encouragement into people's lives. They're doing it selflessly to help others, and don't get paid for any of it themselves. And I admire that! | |
