In this Year 4 Find 1, 10, 100 or 1,000 More or Less lesson, children find up to 1,000 more or less than a given number.
The Year 4 Find 1, 10, 100 or 1,000 More or Less 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.
partitioning: The splitting of a number into different parts. For example: the number 547 can be partitioned into 500, 40 and 7.
exchange: When a digit is taken from one place value column and placed in another.
placeholder: 0 is used to hold a place in a number and maintain its place value.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
For the purple sections of the four levels, copy and paste these from the first sheet of the varied fluency resource.
Scaffolded Examples
• Finding more or less
Support
• Q1: Finding 1, 10, 100 and 1,000 more or less from Base 10, with the number partitioned and no exchanges needed.
• Q2: Finding more from a place value chart where an exchange is needed, counting the column that changes first.
• Q3: Finding less from a place value chart across the placeholder 0, counting the empty column first.
Core
• Q1: Finding 1, 10, 100 and 1,000 more or less from Base 10.
• Q2: Finding more from a place value chart where an exchange is needed.
• Q3: Finding less from a place value chart across the placeholder 0.
Stretch
• Q1: Finding 1, 10, 100 and 1,000 more or less from Base 10, where several answers cross a boundary.
• Q2: Finding more from a place value chart where two exchanges are needed.
• Q3: Finding less from a place value chart across two placeholder 0s.
Reasoning and Problem Solving
Support
• Q1: Reasoning - explaining whether a character has correctly found 10 more or 1,000 less, where only one column changes.
• Q2: Reasoning - explaining whether a statement about the column that always changes is true.
• Q3: Problem Solving - finding four-digit numbers when the tens digit of the answer is given.
Core
• Q1: Reasoning - explaining whether a character has correctly found 100 less or 10 more, including a placeholder 0 and an exchange.
• Q2: Reasoning - explaining whether a statement about the columns that always or sometimes change is true.
• Q3: Problem Solving - finding four-digit numbers when the hundreds digit of the answer is given.
Stretch
• Q1: Reasoning - explaining whether a character has correctly found 1 less or 1 more, where two exchanges are needed.
• Q2: Reasoning - explaining whether a statement about a column never changing, or all four changing, is true.
• Q3: Problem Solving - finding four-digit numbers when two digits of the answer are given.
Deeper Reasoning
The questions in this set focus on identifying the highest and lowest scores in a beach maze, and using the clues to identify the number being described to deepen understanding in finding 1,000 more or less than a given number.
