3 × 5 = 15 people.

The SAME amount of something IN EACH thing is often solved by multiplying.

Example problems

1.  Write a multiplication sentence to each problem and solve.  You can draw pictures to help you.

a)  Four children are playing tennis together. They all brought six balls. How many balls do they have total?

 

 

b)  The Smith family has five members. Each member has a small towel and a bath towel. How many towels hang in the bathroom?
c)   The Jones family orders four pizzas to eat. Each pizza is sliced into four parts.  How many pizza slices do they get?

 

 

d)  A town has three post offices. In each post office there are five

Word problems with two operations

Mr. Johnson usually eats three meals a day.  How many meals does he eat in a normal week?

Again, we have the situation of EACH DAY the SAME thing happens.

7 days × 3 meals a day = _____ meals in a normal week.

This Friday he skipped breakfast.  How many meals did he eat during this week?

Now one day is different.  It is only ONE day though, so we just subtract the one meal
from the total.

days times meals take away the skipped
breakfast
7 × 3 1 = ___

In the following week, he ate three times on Monday, Tuesday, and Friday, and four times on the rest of the days.  How many meals did he eat during the week?

Now we have the one kind of situation three times, and the other kind of situation four times.  We calculate those separately, and then add.

days times meals and rest of 
the days
times meals
3 × 3 + 4 × 4 = ___

Example problems

1.  Fill in the numbers to the number sentences for each problem, and solve.  For the last problems, write the number sentence yourself.  You can write words above the numbers to describe the numbers.  You can also draw pictures to help you!

a)  Mommy bought four egg cartons, and each had six eggs.  Two of the eggs were bad. How many good eggs did Mommy get?

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!
