Paper Power 1 (Multiplication)

I am learning to work out multiplication problems using written working forms.

Kate has 3 containers of strawberries and there are 18 strawberries in each container. How many strawberries are there in total? 3 X 18 = ?

10 10 10

Step 1: Set up the equation with the larger number at the top.

18x 3

4

2

Step 2: Work out 3 X 8 = 24

Put the 4 in the ones column and carry the two tens to the tens column. Do this by writing a 2 above the tens column.

2 tens 4

Step 3: Work out 3 X 10 = 30 (then add the 2 tens you made from the ones.)

3 X 10 = 3030 + 20 = 50Write the 5 in the tens column.

3 X 18 = 54

Ben had 6 containers with 24 counters in each. How many counters does he have in total? 6 X 24 = ?

10

Step 1: Set up the equation with the larger number at the top. 24x 6

4

2

Step 2: Work out 6 X 4 = 24

Put the 4 in the ones column and carry the two tens to the tens column. Do this by writing a 2 above the tens column.

10 10 10 10 10 10 10 10 10 10 10

2 tens and 4

Step 3: Work out 6 X 20 Then add the two tens you made from the ones.

1 hundred 2 tens Plus the two tens we made from the ones.

Now record the 1 in the hundreds column and the 4 tens in the tens column.

There are 8 classes at Forest Park School and 28 students in each class. How many students are there at Forest Park School? 8 X 28 = ?

Now let’s try one without materials

28x 8

4

6

22

Step 1: Set up the equation with the larger number at the top.

Step 2: Multiply 8 by the number in the ones column.

8 X 8 = 64. Record the 4 in the ones column and carry the 6 tens to the tens column.

Step 3: Multiply 8 by the number in the tens column and add any amount you have carried.

8 X 2 = 16 (remember this is 16 tens). Now add the 6 tens you made from the ones.

16 + 6 = 22 (remember this is 22 tens or 2 hundreds ad 2 tens)

Record the 2 in the tens column and the 2 in the hundreds column.

Use standard written form to work out answers to the questions below.

1) 7 X 26 = ?

2) 6 X 38 = ?

3) 9 X 42 = ?

4) 8 X 83 = ?

5) 3 X 56 = ?Need some more practise? Try Pg41 & 42 of Teacher Tools Multiplication and Division Book Numeracy resources
