Part 1: Teens as sums with 10

Sal looks at the 1 in each teen number and thinks about what it really means. 

"Teens as Sums with 10" focuses on understanding how teen numbers can be represented as sums of 10 and another number. Here are the key points:

  1. Understanding Teen Numbers: Teen numbers range from 10 to 19. Each can be split into a base of 10 and an additional value (e.g., 12 = 10 + 2).

  2. Concept of Decimals: Teen numbers illustrate the concept of place values, emphasizing the significance of the 'tens' and 'ones' places.

  3. Addition Skills: Learning to decompose teen numbers helps improve addition and mental math skills by recognizing patterns in how to break down numbers.

  4. Visual Representation: Utilizing visual aids like ten-frames or number lines can enhance understanding of these concepts.

  5. Practical Application: Engaging in activities that involve combining numbers (e.g., using counters or manipulatives) can reinforce the understanding of how to form teen numbers.

  6. Relating to Higher Numbers: Connecting teen numbers to higher place values can lay the groundwork for understanding more complex mathematics later, such as adding larger numbers.

By mastering these points, learners can gain a firm grasp of how to conceptualize and work with teen numbers effectively.
