Maths Year 5 Autumn Addition and Subtraction

Each unit has everything you need to teach a set of related skills and concepts.

Column addition (4- and 5-digit numbers) (suggested as 2 days)

Planning and Activities

Day 1 Teaching
Write 3458 + 2477, 3478 + 2827 and 3455 + 2327. Children arrange by estimation from biggest to smallest answers. Take feedback. Draw out rounding to nearest 1000 to approximate. Model column addition/find exact answers.
Group Activities
-- Discuss which additions of 4-digit numbers are easy/quick to do and which are harder/slower to do and why. Children then work out the answers.
-- Teach children how to add pairs of 5-digit numbers.
Day 2 Teaching
Using a table of hits on a website, find totals, modelling how to use column addition and reminding children to leave a line before the answer so that they can record the ‘carry’ digits.
Group Activities
Use the ‘Exasperating 80 Grand’ in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Use a place value chart to generate pairs of 5-digit numbers to add.
-- Use digits 1 to 8 to create two 4-digit numbers, aiming to have a total between 6000 and 8000.

You Will Need

  • Mini-whiteboards and pens
  • Flipchart and pen
  • Table of hits on a website (see resources)
  • Place value chart (see resources)
  • Red and blue counters
  • Red and blue pens
  • 0 to 8 digit cards

Mental/Oral Maths Starters

Day 1
Place value in 4-digit numbers (pre-requisite skills)

Suggested for Day 2
Add 3 single digit numbers spotting bonds to 10 and doubles (simmering skills)
Pairs to 100 (simmering skills)


Day 1
Practice using compact column addition.

Day 2
Children use column addition to add pairs of 4-digit numbers, and are prompted to make some estimates first.
Children find the total number of hits on a website each day (5-digit numbers).

Mastery: Reasoning and Problem-Solving

  • Fill in the missing digits:
    ☐ ☐ 3 8 4
    + 7 9 8 ☐ ☐
    ☐ 5 2 2 ☐
  • Write an addition of a 5-digit number and a 4-digit number, using the digits 4, 5 and 6, where the answer is 70,000.
  • What mistake has Tom made in this addition? 36,842 + 8543 = 3,141,385

In-depth Investigation: Exasperating 80 Grand
Children use all of the digits 0 to 9 once only to create pairs of five-digit numbers, with a total as close to 80,000 as possible.
