The Year 5 Multiply by 10, 100 and 1,000 PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, deeper reasoning and scaffolded resources. Key learning information about this step:
Key Vocabulary
product: The answer of multiplying two or more numbers together. For example: 30 is the product of 6 x 5.
place value chart: Used to identify the value of the digits that make up a number.
placeholder: 0 is used to hold a place in a number and maintain its place value.
Gattegno chart: A type of place value chart designed to help children recognise the patterns in the way that we count and our number structure.
multiplier: The number we are multiplying by. The digits in the top number are multiplied by the multiplier.
