- Introduction to Place Value:

Start by reviewing or introducing the concept of place value. Remind students that the digits in a number represent different place values.
- Tens and Ones Language:

Use language that emphasizes the tens and ones places. For example, in the number 36, explain that there are 3 tens and 6 ones.
- Model with Objects:

Use physical objects like base-10 blocks or counters to model the addition of tens and ones. Show how to combine tens and ones to create a two-digit number.

Provide examples of two-digit numbers and write them as addition sentences. For example:
For the number 45:

Have students practice writing two-digit numbers as addition sentences. Encourage them to break down the number into tens and ones. This will help the students gain a deeper understanding of how to write and interpret two-digit numbers as addition sentences that involve both tens and ones.
