The Year 5 Divide 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
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.
inverse operations: Used to check working out or to find a starting number by using the opposite operation. Addition is the inverse of subtraction and vice versa. Multiplication is the inverse of division and vice versa.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Moving digits in a place value chart to divide by 10 and 100; dividing by 10 twice in steps.
Support
• Q1: Divide 3- and 4-digit numbers by 10 or 100 in a chart; hint given.
• Q2: Match divisions by 10 and 100 to their answers; hint given.
• Q3: Find the missing numbers when dividing by 10 or 100; hint given.
Core
• Q1: Divide 4- to 6-digit numbers by 10 or 1,000 in a place value chart.
• Q2: Match divisions by 10, 100 and 1,000 to their answers.
• Q3: Find the missing numbers when dividing by 10, 100 or 1,000.
Stretch
• Q1: Divide 5- and 6-digit numbers with placeholders by 100 or 1,000 in a chart.
• Q2: Match mixed divisions to their answers; one answer does not match.
• Q3: Find missing numbers, including dividing more than once.
Reasoning and Problem Solving
Support
• Q1: Reasoning – explain whether a character has divided a 4-digit number by 10 or 100 correctly; hints given.
• Q2: Reasoning – decide whether working that divides by 10 twice is correct and show a different method; hint given.
• Q3: Problem Solving – find numbers which give the same answer when divided by 10 and by 100; hint given.
Core
• Q1: Reasoning – explain whether a character has divided a 5- or 6-digit number by 100 or 1,000 correctly.
• Q2: Reasoning – decide whether working that divides by 1,000 in steps is correct and show a different method.
• Q3: Problem Solving – find numbers which give the same answer when divided by 10, 100 or 1,000.
Stretch
• Q1: Reasoning – explain whether a character has divided by 1,000 correctly using two steps.
• Q2: Reasoning – decide whether working with zero placeholders is correct and show a different method.
• Q3: Problem Solving – find numbers which give the same answer when divided by 10, 100 or 1,000; one number is divided in two steps.
Deeper Reasoning
The questions in this set focus on playing a division game with dice and solving a puzzle to deepen understanding of how to divide whole numbers by 10, 100 and 1,000.
