In this Year 2 Partition Numbers to 100 lesson, children recognise the place value of each digit in a two-digit number (tens and ones).
The Year 2 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
ones: Individual units that make up a whole number.
tens: A group of 10 ones together is the same as 1 ten.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Counting tens and ones in a representation, then reading parts and wholes.
Support
• Q1: Count the tens and ones and whole in a part-whole model; separate stems.
• Q2: Find the tens part, the ones part and the whole; separate stems.
• Q3: Complete a part-whole model.
Core
• Q1: Count the tens and ones in a part-whole model to name the number.
• Q2: Identify the value of each part and the whole.
• Q3: Complete part-whole models using tens and ones and place value digits.
Stretch
• Q1: Complete a part-whole model and sentences with one number given.
• Q2: Complete a part-whole model and sentences for a given value.
• Q3: Complete part-whole models with more than one missing value.
Reasoning and Problem Solving
Support
• Q1: Reasoning - explain whether a part-whole model built from tens and ones correctly partitions the whole.
• Q2: Reasoning - explain whether a statement about tens and ones and the part-whole model shown are accurate.
• Q3: Problem Solving - find three possible wholes and missing parts when the ones part and a range for the whole are given.
Core
• Q1: Reasoning - explain whether a part-whole model matches a Base 10 representation of tens and ones.
• Q2: Reasoning - explain whether a statement about the tens and the ones in a number is correct.
• Q3: Problem Solving - find three possible wholes and missing parts when the tens part and a range for the whole are given.
Stretch
• Q1: Reasoning - explain whether a part-whole model partitions a number into tens and ones, with no representation to check against.
• Q2: Reasoning - explain whether a statement about parts of a whole is correct.
• Q3: Problem Solving - find three possible pairs of parts and their wholes when only a range for the tens and the ones is given.
Deeper Reasoning
The question focuses on problem solving with part-whole models to deepen understanding in recognising the place value of each digit in a two-digit number including tens and ones.
