Continue a Skip-Count with Its Stated Step

Supplied materials

• Paper and a pencil; drawing and spoken explanations are welcome. An adult may read directions and options aloud.
• Supplied worked-case record: Start at 285 and count by fives three times: 290,295,300.
• All quantities and shape descriptions are supplied in the worked example and questions; no purchase or personal information is needed.

Learn the idea

Skip-counting repeatedly adds the same amount. Count by fives, tens, or hundreds according to the stated rule. Crossing a tens or hundreds boundary does not change the step size. Recording each jump prevents a pattern from accidentally switching rules.

Write the starting amount and the stated step size. Add the step once for each requested jump. Check the difference between neighboring terms; it should match the rule every time.

Write the step size beside each arrow. Crossing a place-value boundary does not change the counting rule. Draw three equal-size labeled jumps on a number line.

1. Draw three equal-size labeled jumps on a number line.
2. Follow the worked example. Point to each number or shape feature and say what it tells you.
3. Write the starting amount and the stated step size.
4. Try the question and then the three practice questions. Check your answers and explain any change you make.
