In this Year 3 Partition Numbers to 1000 lesson, children recognise the place value of each digit in a three-digit number (hundreds, tens, ones).
The Year 3 Partition 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
partitioning: The splitting of a number into different parts. For example: the number 547 can be partitioned into 500, 40 and 7.
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 a number shown in Base 10 into hundreds, tens and ones, with sentence stems that become less structured across the examples, then finding a missing part in a part-whole model.
Support
• Q1: Partition a number shown in Base 10; number of hundreds given.
• Q2: Find the missing part in a part-whole model; missing ones.
• Q3: Partition a whole into three parts; the hundreds part is given.
Core
• Q1: Partition a number shown in Base 10; one placeholder.
• Q2: Find the missing part in a part-whole model; one placeholder.
• Q3: Partition a whole into three parts; placeholder in tens or ones.
Stretch
• Q1: Partition a number shown in Base 10; one placeholder; Base 10 not in place value order.
• Q2: Find two missing parts in a part-whole model; one placeholder.
• Q3: Partition a whole into three parts; unconventional part-whole model; written calculation included.
Reasoning and Problem Solving
Support
• Q1: Reasoning - explain whether a 3-digit number has been partitioned correctly; no placeholder; Base 10 provided.
• Q2: Reasoning – find and explain the mistake; no placeholders; Base 10 provided.
• Q3: Problem Solving - find three 3-digit numbers that fit a given hundreds and tens value; partition each one.
Core
• Q1: Reasoning - explain whether a 3-digit number has been partitioned correctly; one placeholder.
• Q2: Reasoning – find and explain the mistake; one placeholder.
• Q3: Problem Solving - find three 3-digit numbers with 0 as a placeholder; partition each one.
Stretch
• Q1: Reasoning explain whether a 3-digit number has been partitioned correctly; one placeholder; more than 9 ones/tens used in the partition.
• Q2: Reasoning - find and explain the mistake; one placeholder; written calculation given.
• Q3: Problem Solving - find three 3-digit numbers using two clues; partition each one.
Deeper Reasoning
The question in this set focuses on using the given clues to identify the possible numbers to deepen understanding in recognising the place vale of each digit in a three-digit number.
