Understanding Place Value – Define Place Value – Place value determines the value of a digit in a number based on its position. – Value of each position – Each step to the left increases value 10 times: 1s, 10s, 100s, etc. – Examples: ones to billions – Ones: 7; Tens: 70; Hundreds: 700; Thousands: 7,000 – Practice with large numbers – Convert ‘five hundred million’ to digits and vice versa. | Begin by explaining the concept of place value, which is the foundation of our number system. Emphasize that the position of each digit in a number determines its value. Use clear examples starting from the ones place and moving left to the billions place to illustrate how each step increases the value tenfold. Provide students with examples of large numbers, both in words and digits, and ask them to convert between the two. This will help them grasp the concept of place value in the context of very large numbers. Encourage students to practice with numbers up to one billion to ensure they are comfortable with place value across a wide range.

Numbers in Words: Writing and Converting – Writing numbers with words – Learn to express digits as written words – Examples: 23 and 467 – 23 is written as Twenty-three, 467 as Four hundred sixty-seven – Practice conversion together – Convert numbers from digits to words as a class activity – Understanding place value | This slide introduces the concept of writing numbers in word form, which is a key aspect of understanding place value. Start by explaining the basic rules for writing numbers in words, such as writing out the number 23 as ‘Twenty-three’. Use clear examples to illustrate these rules, and then engage the class in a group activity to practice converting digits to words. Emphasize the importance of place value in determining the position and value of each digit in a number. This will help students grasp the concept of larger numbers and prepare them for writing numbers up to one billion.

Converting Words to Digits – Writing words as numbers – Examples: Words to digits – ‘Five thousand’ becomes 5,000 and ‘Seventy-eight million’ is 78,000,000 – Group practice activity – Convert word descriptions into number format as a class – Understanding place value – Recognize the value of each digit in a large number | This slide is aimed at helping fourth-grade students understand how to convert numbers written in word form into digit form, focusing on numbers up to one billion. Start by explaining the concept of place value and its importance in understanding large numbers. Use clear examples like ‘Five thousand’ which translates to 5,000 and ‘Seventy-eight million’ which is written as 78,000,000 to illustrate the conversion process. Engage the class with a group practice activity where students work together to convert a list of numbers from words to digits. This will help reinforce their understanding of place value and the base-ten number system. Encourage students to ask questions and provide assistance as needed to ensure comprehension.
