Multiples of 3

Multiples of 3

These are three differentiated worksheets. Recall multiplication and division facts for multiplication tables up to 12 × 12. Recognise and use factor pairs and commutativity in mental calculations. Watch for: Children may think that any number with 3 ones is a multiple of 3. An early mistake when counting in 3s will affect all subsequent multiples. Children may always begin counting from 3 to find a larger multiple of 3, when they could use the multiples they already know to find the new information. In the higher ability worksheet ( with three faces), children explore how to recognise if a number is a multiple of 3 by finding its digit sum: if the sum of the digits of a number is a multiple of 3, then the number itself is also a multiple of 3. Challenge by asking : How do you find the digit sum of a number? How can you tell if a number is a multiple of 3? Are the multiples of 3 odd or even? In the foundation worksheet (one face), children explore the link between counting in 3s and the 3 times-table to understand multiples of 3 in a range of contexts. They use number tracks and hundred squares to represent multiples of 3. Ask: What is the next multiple of 3? What is the multiple of 3 before? How many 3s are there in?
