The concept on skip counting by 7’s or sevens is an essential skill to learn when making the jump from counting to basic addition.
The sequence chart will help us to write the number to complete the series which involves skip counting by sevens up to 14 times.
Skip counting by 7’s up to 14 times –
7, 1 time 
14, 2 time 
21, 3 time 
28, 4 time 
35, 5 time 
42, 6 time 
49, 7 time 
56, 8 time 
63, 9 time 
70, 10 time 
77, 11 time 
84, 12 time
