How it works
Skip counting by 7 turns days into weeks: 7, 14, 21, 28. The digits give few clues, so this chart lights the 20 stops to 140 and shows where each jump lands. A strip with gaps sits below.

Two moves on the chart
A jump of 7 moves one of two ways. From columns 4 to 10 it goes one row down and three squares left, because 7 is 10 take away 3. From columns 1 to 3 it stays in its row and goes seven squares right, as in 21 to 28. The ones digits run 7, 4, 1, 8, 5, 2, 9, 6, 3, 0 and start again at 77. Before the 0, those are the endings of the 3s read backwards.
Read the weeks, fill the strip
The list All 20 jumps, further down, gives each stop in weeks. Type the strip's missing numbers, press Check, then New counting strip.
- On a calendar the dates in one column are 7 apart: reading down is the count from a new start.
- Add 7 as 5 and 2. From 28, 5 more is 33 and 2 more is 35.
- Bigger number? Double its last digit, take that from the rest: 161 gives 16 − 2 = 14, a stop.
Questions and answers
What are the numbers when skip counting by 7s?
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91 and 98, then 105, 112, 119, 126, 133 and 140. A chart that stops at 100 shows 14 of the 20 stops.
Is there a trick for 7 skip counting?
No digit trick as neat as the 5s or the 9s. Two things help: every stop is a whole number of weeks, so 14 is 2 weeks and 70 is 10, and the 7 times table chart holds the same numbers.
Can I print a page of the 7s?
Yes: Print 6 counting strips, under the strip, is a page of six strips of the 7s, and the answers print on a second sheet. Print the chart gives the chart alone. For rows, choose Count by 7s to 84 on skip counting worksheets.
