Skip Counting by 8s (181)

Teaching Notes

Introduce skip counting by 8s as repeated addition or a stepping stone to multiplication. Emphasize observing the pattern in the units digit (8, 6, 4, 2, 0, 8...). Use a number line or 100-chart to visualize the jumps and reinforce the pattern.

Vocabulary

Skip counting: Counting numbers by skipping others.

Pattern: A predictable rule or sequence.

Common Mistakes

• Losing track of the count after a few numbers, especially when crossing tens.
• Arithmetic errors when repeatedly adding 8.
• Not recognizing the repeating pattern in the ones digit, which can help self-correct.
• Skipping numbers or miscounting.
• Incorrectly adding 8 each time, especially after larger numbers.
• Losing track of the sequence.
