Unit Summary
In this unit pupils will represent counting in sevens as the 7-table, explaining the relationship between adjacent multiples. The unit also looks at odd and even patterns in times tables and identifies square numbers.
Lesson Summary
You will learn to use divisibility rules for 2, 3, 4, 5, 6, 8 and 10 times tables to solve problems.
Key Notes
- There are divisibility rules for 2, 4 and 8 which involve halving, halving twice and halving three times.
- Multiples of 10 have a zero in the ones and multiples of 5 have a 5 or a zero in the ones.
- Multiples of 3 have a digit sum of 3
- Multiples of 6 are even numbered multiples of 3
Vocabulary To Learn
- Divisible: divisibility is a number's ability to be exactly divided by another number, leaving no remainder.
- Divisibility rules: divisibility rules let you test if one number is divisible by another, without having to do too much calculation.
Common Mistakes To Avoid
- Pupils may struggle to apply multiple divisibility rules simultaneously.
3 Quick Questions (With Answers)
1. Solve this in steps: explain the method from this lesson and why each step matters.
There are divisibility rules for 2, 4 and 8 which involve halving, halving twice and halving three times. Multiples of 10 have a zero in the ones and multiples of 5 have a 5 or a zero in the ones.
2. Use this key word in a maths sentence and explain it clearly. 'Divisible'
divisibility is a number's ability to be exactly divided by another number, leaving no remainder. Use this word when showing your method, then check your final answer is reasonable.
3. Spot and fix this common maths mistake.
Mistake: Pupils may struggle to apply multiple divisibility rules simultaneously. Correction: Have the rules visible, practise applying multiple rules step-by-step to ensure understanding and accuracy.
