Repeated Addition - On a Number Line


Multiplying on a number line


Five jumps, each is two steps. 5 × 2 = 10.

Example problems

1.  Write the multiplication sentence that the jumps on number line illustrate.
  
  


2.  Continue and draw jumps to fit the multiplication problem.

6 × 4 = 

 5 × 5 = 
 

3 × 10 =


Find 4 × 3 by skip-counting


Take four 'skips'.  Add three each time.  Notice where you land when 'skipping':
 
You landed at 3, 6, 9, 12.   4 × 3 = 12.
 
3.  Add repeatedly (or skip-count) to multiply.  You can use the number line to help.
3 × 2 =
6 × 3 =
4 × 5 =
3 × 10 =
2 × 11 =
3 × 7 =

4.  Fill in the multiplication table of 2!
1 × 2 =
2 × 2 =
3 × 2 =
4 × 2 =
5 × 2 =
6 × 2 =
7 × 2 =
8 × 2 =
9 × 2 =
10 × 2 =
11 × 2 =
12 × 2 =

Repeated Addition (2)

Multiplication as repeated addition

REMEMBER : 
5 + 5 + 5 = 3 x 5 = 15

Example : 

1.   2 + 2 + 2                     = 2 x 3 = 6

2.   5 + 5                           = 5 x 2 = 10

3.   1 + 1 + 1 + 1 + 1 + 1  = 1 x 6 = 6 

4.   3 lots of 10                = 10 x 3 = 30

5.   10 lots of 5                = 5 x 10 = 50

6.   7 lots of 2                  = 2 x 7 = 14

7.   3 + 3 + 3 + 3 + 3        = 5 lots of 3 = 15

8.   2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 8 lots of 2 = 16

9.   4 lots of 10                = 4 x 10 = 40

10.   6 lots of 2                =  6 x 2 = 12

Repeated Addition - With Object (1)

      Multiplication as Repeated Addition

1.

Repeated Addition
 Repeated Addition: 7 + 7 + 7 + 7 + 7 + 7
                         so
                        7 x 6 = 42                                                                                  

2.

Repeated Addition
 Repeated Addition: 5 + 5 + 5 + 5 = 20
                        so
                        5 x 4 = 20
  

3.


Repeated Addition
 Repeated Addition: 10 + 10 + 10 = 30
                             so
                          10 x 3 = 30

4.

Repeated Addition
 Repeated Addition: 8 + 8 + 8 + 8 = 32
                        so
                       8 x 4 = 32



5.

Repeated Addition
 Repeated Addition: 3 + 3 + 3 + 3 = 12
                          so 
                         3 x 4 = 12

6.

Repeated Addition
 Repeated Addition: 6 + 6 + 6 + 6 = 24
                          so
                         6 x 4 = 24
      

7.

Repeated Addition
 Repeated Addition: 2 + 2 + 2 = 6
                         so
                         2 x 3 = 6 


   

8.

Repeated Addition: 4 + 4 + 4 + 4 = 16
                         so
                        4 x 4 = 16

9.


Repeated Addition: 2 + 2 + 2 = 6
                         so
                        2 x 3 = 6

10.

Repeated Addition: 4 + 4 = 8
                          so
                       4 x 2 = 8
