Count by Tens Dot to Dot: 10, 20, 30 up to 100

Ten dots carry the whole hundred on this 2nd grade dot-to-dot page. They sit in the cream panel labelled 10, 20, 30 and on up to 100, printed in the largest number chips this family uses, with the 10 ringed in orange to start; the remainder of the outline is already drawn in grey, so ten lines finish the picture. The strip along the bottom holds the tens in circles, 10 through 100, which is the counting sequence a second grader is expected to have by heart and the one they can check against here if they do not.

Counting in tens is where place value first becomes visible as a pattern rather than a rule: every number on this page ends in a zero, and the digit in front of it climbs by one each time. That makes the sequence the easiest of the skip counts to say and the most useful to own, since it underpins adding ten to any number and reading a hundred square. The only place children stumble is the last step, where ninety goes to one hundred and the shape of the number changes, and this page puts that step at the very end where it can be watched. Ask what happens after ninety before the pencil gets there.

Print the PDF free and ask for the tens to be counted backwards from a hundred once the picture is done, since that reverse run is far less practised than the forward one. Colour it in afterwards. Count by fives is the same page with a smaller step, count by twos is smaller again, and number line to 100 counting in tens moves the identical sequence onto a ruled line where the spacing is to scale.
