# Skip Counting by 3's

The concept on skip counting by 3’s or threes 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 threes up to 33 times.

Skip counting by 3’s up to 33 times –

 3, 1time 6, 2time 9, 3time 12, 4time 15, 5time 18, 6time 21, 7time 24, 8time 27, 9time 30, 10time 33, 11time 36, 12time 39, 13time 42, 14time 45, 15time 48, 16time 51, 17time 54, 18time 57, 19time 60,20time 63, 21time 66, 22time 69, 23time 72, 24time 75, 25time 78, 26time 81, 27time 84, 28time 87, 29time 90, 30time 93, 31time 96, 32time 99, 33time

I. Now look at the chart above where every third number is in dark yellow color and fill in the blanks below:

 (i) 3 × 32 = _____ (iv) 3 × 14 = _____ (vii) 3 × 26 = _____ (x) 3 × 29 = _____ (xiii) 3 × 15 = _____ (ii) 3 × 33 = _____ (v) 3 × 19 = _____ (viii) 3 × 22 = _____ (xi) 3 × 30 = _____ (xiv) 3 × 11 = _____ (iii) 3 × 23 = _____ (vi) 3 × 17 = _____ (ix) 3 × 28 = _____ (xii) 3 × 20 = _____ (xv) 3 × 25 = _____

II. Complete the skip counting series by 3s:

(i) 0, 3, 6, ____, ____, ____, ____, ____.
