Teaching students to take apart teen numbers can be a challenging task as it requires a solid understanding of place value and number operations. However, incorporating fun and engaging activities into your instruction can make the learning process more enjoyable and effective. Here are some ideas for activities to help your students break down teen numbers into individual digits:

1. Teen Number Towers

In this activity, students use unifix cubes to build towers that represent teen numbers. For example, a tower of 13 cubes would represent the number 13. Once they have built the towers, they can take them apart and count the individual cubes to identify the digits that make up the number.

2. Memory Match

Create a set of memory match cards with teen numbers on one side and the individual digits on the other. Students take turns flipping over cards and matching the teen number to its corresponding digits. This game can also be adapted to include addition or subtraction problems with teen numbers.

3. Place Value Chart

Provide students with a place value chart and a set of teen number cards. As a class, demonstrate how to place each number on the chart and then break it apart by saying the numbers out loud. After modeling several examples, students can work in pairs or small groups to place and take apart teen numbers independently.

4. Number Line Breakdown

Using a number line, have students identify the teen number they want to break down and then place individual counters on the appropriate spots on the line. For example, for the number 16, students would place one counter on the number 10 and six counters on the number 6. They can then count the total number of counters and write out the digits that make up the number.

5. Teen Number Scavenger Hunt

Hide teen number cards throughout the classroom or outdoor space. Students work in pairs or small groups to find the cards and then break down the numbers by saying the digits out loud. For an added challenge, you can ask students to add or subtract numbers as they find them.

6. Ten and Some More

Create a set of cards that show ten frames filled with dots. Students draw a card and identify how many dots are in the ten frame and then count the additional dots to determine the teen number. For example, a card with eight dots in the ten frame and five additional dots would represent the number 18.

By incorporating these activities into your instruction, you can help students develop a strong understanding of place value and number sense as they break down teen numbers. These fun and engaging activities make learning a more enjoyable experience for your students while also deepening their knowledge of mathematical concepts.
