Teaching Notes

Focus: Skip-Counting by 2, 5, and 10. Use the worked example and teaching sequence below to explain the reasoning before independent practice.

Before You Begin

Count by an equal step.

Teaching Steps for Parents and Teachers

Identify the repeated step.
Add that amount to find the next number.
Use the number of steps to connect the pattern to multiplication.

Worked Examples

Fill in: 5, 10, 15, □

The step is 5.
15 + 5 = 20.

Answer: 20

Common Mistakes and How to Help

Use the same step throughout the pattern.

Can you show the numbers as equal groups?

Questions to Check Understanding

Can you show the numbers as equal groups?
Which step explains your answer?
Can you apply the same reasoning when the numbers change?

Practice Advice

Work through the example together. Ask the learner to explain the first two problems, then try three independently. Review the first incorrect step before assigning more practice.

Next Practice

Use New Numbers to practice the same skill with different values.
If the learner needs help, return to the example and model each step before trying again.
