Counting Numbers 10–20 · Counting Numbers 10–20 · Match Pictures and Numbers

Teaching Notes

Focus: Matching pictures of quantities from 10 to 20 with numerals. Group ten objects, count the remainder, and match the total.

Before You Begin

• Say number names in order.

Teaching Steps for Parents and Teachers

1. Count the objects in each picture, grouping ten objects when helpful.
2. Match each picture to the numeral with the same total.
3. Check the match by counting the group of ten and remaining objects.

Worked Examples

Match the picture to its number: ● ● ● ● ● ● ● ● ● ● ● ● ● ● → 13, 14, 15

1. Count ten dots as one group of ten.
2. Count four more dots: 10 + 4 = 14.
3. Connect the picture to 14.

Answer: 14

Common Mistakes and How to Help

Forgetting to include the objects left after making a group of ten.

After counting ten, how many dots remain? Add them to ten.

Questions to Check Understanding

• How many full groups of ten are shown?
• How many objects remain?
• Which numeral names the total?

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.
