Skip count in 100s means skipping 100 places (digits Remember
at the tens and ones places remain the same).
For skip counting, we fix
For example, 7108, 7208, 7308, 7408, 7508 a number to skip, start
Skip count in 1000s means skipping 1000 places the count from a number,
(digits at the hundreds, tens and ones places remain skip the fixed number and
continue counting.
the same).
For example, 2845, 3845, 4845, 5845, 6845, 7845
More Than and Less Than
Consider the number 8135.
To find a number 2 more than 8135, we add 2 to 8135, i.e., 8135 + 2 = 8137.
To find a number 3 less than 8135, we subtract 3 from 8135, i.e., 8135 – 3 = 8132.
