In this Year 2 Flexibly Partition Numbers to 100 lesson, children recognise the place value of each digit in a two-digit number (tens and ones).
The Year 2 Flexibly Partition Numbers to 100 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, usually tens and ones. For example, the number 47 can be partitioned into 40 and 7.
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.
part-whole model: A representation showing the whole number and the parts it has been split into.
representation: A number that has been shown in different ways. For example, in numerals, words or using equipment such as Base 10 or a place value chart.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Partitioning 35 into tens and ones, unbundling a ten to partition it flexibly, then continuing a pattern.
Support
• Q1: Partition a 2-digit number three ways, with one way completed.
• Q2: Continue a pattern, with the first part of each answer given.
• Q3: Find the missing part of two part-whole models, with Base 10.
Core
• Q1: Partition a 2-digit number in three different ways, using Base 10.
• Q2: Continue a pattern of flexible partitions.
• Q3: Find the missing part when the given part includes ones.
Stretch
• Q1: Partition a 2-digit number three ways, not using a given number.
• Q2: Continue a pattern of partitions until it is complete.
• Q3: Find the whole from two given parts.
Reasoning and Problem Solving
Support
• Q1: Reasoning – decide whether a further bundle of ten and the straws left over are correct, supported by an image of the straws.
• Q2: Reasoning – decide whether a part-whole model shows a correct flexible partition, with the whole and both parts shown in Base 10.
• Q3: Problem Solving – find two items that can be bought with a given amount, from a choice of eight, with two combinations to find.
Core
• Q1: Reasoning – decide whether the number of further bundles of ten and the straws left over are correct, supported by an image of the straws.
• Q2: Reasoning – decide whether a part-whole model shows a correct flexible partition, with Base 10 alongside to check against.
• Q3: Problem Solving – find two items that can be bought with a given amount, from a choice of eight or ten, with three combinations to find.
Stretch
• Q1: Reasoning – decide whether the number of further bundles of ten and the straws left over are correct, with no image of the straws to work from.
• Q2: Reasoning – decide whether a part-whole model shows a correct flexible partition, with no Base 10 support.
• Q3: Problem Solving – find two items that can be bought with a given amount, from a choice of ten, finding every possible combination.
Deeper Reasoning
The question in this set focuses on flexibly partitioning numbers in various ways to deepen understanding in recognising the place value of each digit in a two-digit number (tens and ones).
