Maths Year 1 Autumn Addition and Subtraction

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

Adding by counting on (suggested as 4 days)

Planning and Activities

Day 1 Teaching
Demonstrate how to add by counting on using a ‘bus’. Sit 5 soft toys on a table: They are on a bus. Let toys get on the bus and demonstrate how we count on to work out the total now on the bus.
Group activities
-- Showing 5 fingers and counting on to find total of fingers on the other hand.
-- Roll 2 spotty dice (one with 5 dots) and find the total by counting on.

Day 2 Teaching
Wave a hand. Five. Children do the same. Ask them to hold up 1 more finger. 5 and 1 more makes? Say 5 waving the hand, then 6 indicating the extra finger. Also model adding 2, 3, 4 and 5.
Group activities
-- Make a snake and add on cubes. Add the 2 colours together.
-- Add spots on dominoes and put them in order.

Day 3 Teaching
Draw 7 smiley faces on a picture of a bus. Allow 1, 2 or 3 people to get on and model adding by counting on. Also use frogs on a log.
Group activities
-- Roll 2 spotty dice and add on 1, 2 each time. Write the sentence.
-- Work out how many dogs are in the rescue centre by adding on and recording number sentence.

Day 4 Teaching
Show 5 beads on 20-bead bar. Children do same on their 20-bead strings. Roll a 1, 2, 3 dice. Model counting on that number, e.g. say 6, 7 as you slide beads across 1 at a time. Repeat.
Group activities
Use the 'Dotty Triangle Corners' in-depth problem-solving investigation below as today’s group activity.
Or, use these activities:
-- Choose 5-10 on bead string and add on 1, 2 or 3 onto this number.

Mastery: Reasoning and Problem-Solving

  • Draw 5 faces on a bus. Let 2 or 3 people get on. How many on the bus now? Write the addition.
  • What is 5 add 4?
  • Use the line below to help you complete these sums. Point at the first number and count on:
    5 + 3 = ☐
    6 + 1 = ☐
    4 + 4 = ☐
    7 + 2 = ☐

  • 5 little frogs
    Sitting on a log
    On hop 3
    How many can there be?

In-depth Investigation: Dotty Triangle Corners
Children use trial and improvement to find different ways of making a given total by adding three numbers.
