Place value - Tens and ones using addition - Presentation

The lesson on 'Tens and Ones using Addition' focuses on enhancing students' understanding of place value in the context of addition. The lesson begins with a discussion prompt, encouraging students to consider what it means to look at tens and ones in addition problems. The teaching slides guide students through various activities that involve matching number sentences to the correct numbers, such as pairing "60 + 4" with "64", and "20 + 2" with "22". This reinforces the concept of tens and ones and how they contribute to the total value of a number.

Further activities delve deeper into place value understanding, where students complete part-whole models and write corresponding number sentences. For example, they will use the numbers "30" and "4" to create the number "34" in various addition sentences. The lesson also includes reasoning tasks where students identify and correct mistakes in addition, such as correcting "60 + 3 = 603" to "60 + 3 = 63", and filling in missing numbers in sequences to strengthen their grasp of tens and ones in numerical patterns. The lesson culminates with independent work, where students cut out part-whole models and write addition sentences, fostering their ability to work with and understand place value in a practical and engaging manner.
