The Year 4 Round to the Nearest 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
rounding: When a number is replaced with an approximated value. Numbers are often rounded to the nearest 10, 100 or 1,000.
multiple: A product of one number multiplied by another number. For example: multiples of 10 are the products of numbers multiplied by 10.
midpoint: The point on a number line that is exactly halfway between the start and end values.
place value chart: Used to identify the value of the digits that make up a number.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Rounding on fully labelled number lines with sentence stems, and rounding from a place value chart.
Support
• Q1: Round a four-digit number on a number line with extra labels given.
• Q2: Round the number in a place value chart, with a hundreds digit reminder.
• Q3: Sort three numbers into a Carroll diagram, with a reminder given.
Core
• Q1: Round a four-digit number on a number line with the midpoint labelled.
• Q2: Round the number shown in a place value chart.
• Q3: Sort four numbers into a Carroll diagram by rounding and odd or even.
Stretch
• Q1: Round a number with only the end values labelled on a number line.
• Q2: Round a number in a place value chart with a zero or a 5 in the tens column.
• Q3: Sort five numbers, one written in words, into a Carroll diagram.
Reasoning and Problem Solving
Support
• Q1: Reasoning – explain whether a character has rounded a multiple of 100 to the nearest 1,000 correctly.
• Q2: Reasoning – check three rounded multiples of 100 for an error, with a reminder about the hundreds digit.
• Q3: Problem Solving – make four-digit numbers from digit cards that round to a given multiple of 1,000, with the first digit given.
Core
• Q1: Reasoning – explain whether a character has rounded a four-digit number to the nearest 1,000 correctly.
• Q2: Reasoning – check three rounded four-digit numbers for an error.
• Q3: Problem Solving – make four-digit numbers from digit cards that round to a given multiple of 1,000.
Stretch
• Q1: Reasoning – explain a rounding where the tens digit is 5 or the number is just below the midpoint.
• Q2: Reasoning – check three rounded numbers, including a number below 500 and midpoint cases, for an error.
• Q3: Problem Solving – make odd or even four-digit numbers from digit cards that round to a given multiple of 1,000.
Deeper Reasoning
The questions in this set focus on problem solving with rounding to deepen understanding in rounding any number to the nearest 1,000.
