The Year 3 Spot the Pattern 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
place value chart: Used to identify the value of the digits that make up a number.
place value counters: A physical resource which represents numbers. They are usually in different colours and have different numbers written on them, to represent ‘ones’, ‘tens’, ‘hundreds’ etc.
function machines: A diagram that represents a machine. It takes an input, applies a rule to it, such as addition, subtraction, multiplication or division, and delivers the answer as an output.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
For the purple sections of the four levels, copy and paste these from the first sheet of the varied fluency resource.
Scaffolded Examples
• Adding ones with sentence stems and Base 10; adding tens and hundreds with sentence stems and Base 10; subtracting ones, tens and hundreds with sentence stems and Base 10.
Support
• Q1: Adding or subtracting the same number with 1s, 10s and 100s; shown with Base 10.
• Q2: Using a number fact to complete additions and subtractions with 1s, 10s and 100s; place value counters provided.
• Q3: Two function machines with addition and subtraction.
Core
• Q1: Adding and subtracting the same number with 1s, 10s and 100s; shown with Base 10.
• Q2: Using a number fact to complete additions and subtractions with 1s, 10s and 100s.
• Q3: A two-step function machine with addition and subtraction.
Stretch
• Q1: Adding or subtracting the same number with 1s, 10s and 100s; shown with Base 10; including missing numbers.
• Q2: Using a number fact to complete additions and subtractions with 1s, 10s and 100s; two numbers missing per number sentence.
• Q3: A two-step function machine with addition and subtraction; missing input and output.
Reasoning and Problem Solving
Support
• Q1: Reasoning - deciding whether changing the order of two calculations changes the answer; place value chart included; both calculations add or subtract.
• Q2: Reasoning - deciding whether the output of two function machine rules is correct; both rules add or subtract.
• Q3: Problem Solving - choosing a number so that one named column changes; number sentences are given to complete.
Core
• Q1: Reasoning - deciding whether changing the order of two calculations changes the answer; both calculations add or subtract.
• Q2: Reasoning - deciding whether the output of two function machine rules is correct; one rule adds and the other subtracts.
• Q3: Problem Solving - choosing a number so that one named column changes, with a size condition that rules out some of the numbers; number sentences are given to complete.
Stretch
• Q1: Reasoning - deciding whether changing the order of three calculations changes the answer; calculations include add and subtract.
• Q2: Reasoning - deciding whether the two rules of a function machine are correct.
• Q3: Problem Solving - choosing two numbers, one added and one subtracted, with the column not named and a size condition to meet.
Deeper Reasoning
The questions in this set focus investigating the clues to identify the pattern to deepen understanding in adding and subtracting numbers mentally, including three-digit numbers and ones, three-digit numbers and tens and three-digit numbers and hundreds.
