Skip-Count by 10s and 100s within 1000: Mixed Practice

Tens jumps and hundreds jumps change different digits.

A hundreds jump moves to the next hundred.

Read it: Jump, don't count by ones

You are standing on 40 on the number line. You could count 41, 42, 43 all the way. Look at the three jumps of ten — they land on 70.

1. Find 40 on the line. That is where you start.
2. Jump ten three times: 50, then 60, then 70.
3. Read the three hops as 40 + 30 = 70.

Counting 41, 42, 43 all the way to 70 works, but it is slow and easy to lose track.

Each jump is the same size, so you land on the next number of the count without counting every one in between.

You already know 40 plus 10 is 50, so one jump replaces counting 41 through 49.

Jump the same amount each time instead of counting by ones.

103 + 10 = ___ — 113. 1 jump of 10 from 103 lands on 113 — 1 mark along, not 10 little steps.
