In this Year 3 Flexible Partitioning of Numbers to 1000 lesson, children recognise the place value of each digit in a three-digit number (hundreds, tens, ones).
The Year 3 Flexible Partitioning of Numbers to 1000 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
Base 10: A physical resource which represents numbers. The small cubes represent ‘ones’; the rods represent ‘tens’ and are made up of 10 small cubes; the squares represent ‘hundreds’ and are made up of 10 rods; the large cubes represent ‘thousands’ and are made up of 10 squares.
flexible partitioning: The splitting of a number into different parts in different ways. For example: the number 64 could be broken down into 5 tens and 14 ones.
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.
Scaffolded Examples
• Guided practice partitioning 152 in Base 10, giving fewer parts each time.
Support
• Q1: Partition a number shown in three groups of Base 10; two parts given.
• Q2: Partition a number shown in three groups of Base 10; one part given.
• Q3: Complete three partitioning statements; three parts, one given; numbers given to choose from; Base 10 provided.
Core
• Q1: Partition a number shown in three groups of Base 10; one part given.
• Q2: Partition a number shown in three groups of Base 10; no parts given.
• Q3: Complete three partitioning statements; two parts, one given; Base 10 provided.
Stretch
• Q1: Partition a number shown in three groups of Base 10; no parts given.
• Q2: Partition a number shown in four groups of Base 10; no parts given.
• Q3: Complete three partitioning statements; two parts, one given in different places; no Base 10.
Reasoning and Problem Solving
Support
• Q1: Reasoning – identifying who has partitioned a 3-digit number correctly; Base 10 shown for each part; no placeholder.
• Q2: Reasoning - identifying which of two number sentences does not match the number shown in Base 10; hundreds, tens and ones in place value order.
• Q3: Problem Solving - partition a 3-digit number into three parts in three different ways; one part given.
Core
• Q1: Reasoning – identifying who has partitioned a 3-digit number correctly; no Base 10 shown; placeholder in the tens.
• Q2: Reasoning - identifying which of three number sentences does not match the number shown in Base 10; hundreds and ones; placeholder in tens.
• Q3: Problem Solving - partition a 3-digit number into three parts in three different ways; no parts given; each part greater than 100.
Stretch
• Q1: Reasoning - identifying which of three children is incorrect when the number itself is not given; regrouped tens and ones.
• Q2: Reasoning - identifying which of three number sentences does not match the number shown in Base 10; hundreds, tens and ones; regrouped tens and ones.
• Q3: Problem Solving - partition a 3-digit number into three parts in three different ways; no parts given; each part greater than 100 and not a multiple of 100.
Deeper Reasoning
The question in this set focuses on using the given clues to identify the possible numbers in the part-whole model to deepen understanding in recognising the place vale of each digit in a three-digit number.
