The Year 4 9 Times Table and Division Facts 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
product: The answer of multiplying two or more numbers together. For example: 30 is the product of 6 x 5.
multiple: A product of one number multiplied by another number. For example: multiples of 10 are the products of numbers multiplied by 10.
inverse operations: Used to check working out or to find a starting number by using the opposite operation. Addition is the inverse of subtraction and vice versa. Multiplication is the inverse of division and vice versa.
digit sum: The total of the digits within a number. For example, 12 has the digit sum of 3 because 1 + 2 is 3.
Varied Fluency
Knowledge Organiser
• Designed to support all children via key information and examples.
Scaffolded Examples
• Finding 9s facts from number pieces of 9 with step-by-step stems; writing a fact family for an array.
Support
• Q1: Use 10 times table to find 9 times table facts; subtraction amount labelled.
• Q2: Match three 9 times table facts to their inverse divisions; a reminder is given.
• Q3: Solve one-step x and ÷ 9 problems; the bar models are fully labelled.
Core
• Q1: Use 10 times table to find 9 times table facts; subtraction amount blank.
• Q2: Match three 9 times table facts to their inverse divisions; one division doesn’t match.
• Q3: Solve one-step x and ÷ 9 problems; a bar model to complete.
Stretch
• Q1: Work backwards from a 10 times table or 9 times table fact to find the number of groups.
• Q2: Match 9 times table facts to the division with 9 as the answer.
• Q3: Solve two-step problems with 9s; a bar model for the first step.
Reasoning and Problem Solving
Support
• Q1: Reasoning – decide if a count in 9s up to five 9s is right; number line given.
• Q2: Reasoning – check working that uses the 10 or 3 times tables to find a 9s fact; bar model given.
• Q3: Problem Solving – find multiples of 9 from two clues; number line given.
Core
• Q1: Reasoning – decide if a count in 9s is right, finding where a mistake begins.
• Q2: Reasoning – check working and judge reasoning; no bar model.
• Q3: Problem Solving – find 2-digit numbers from digit clues.
Stretch
• Q1: Reasoning – judge counts on and back in 9s from larger multiples of 9.
• Q2: Reasoning – check working by linking methods to inverse facts and judging when a pattern stops working.
• Q3: Problem Solving – find 3-digit multiples of 9 from digit clues.
Deeper Reasoning
The questions in this set focus on problem solving with the 9 times table to deepen understanding in recalling multiplication and division facts for the 9 times table, and recognising and using factor pairs and commutativity in mental calculations.
