The Year 1 Add or Subtract 1 or 2 PowerPoint guides both teachers and children through the lesson, including use of the varied fluency, reasoning and problem solving, practical activities and continuous provision resources. Key learning information about this step:
Key Vocabulary
1 more: 1 more is the next number when we count on.
1 less: 1 less is the number before when we count back.
2 more: To add 2, we can add 1 two times.
2 less: To subtract 2, we can subtract 1 two times.
Adult-Led Practical Activities
• Activity 1: Change the Tower. Children add or take off 1 or 2 cubes and say the number sentence.
• Activity 2: Add or Subtract? Children act out short stories and decide whether to add or subtract.
You will need:
• interlocking cubes and number cards 0 to 10
• cards showing +1, +2, -1 and -2
• small toys, e.g. ducks, sea creatures, dinosaurs, cars or teddies, and mini whiteboards
Why not try…
• Spinner Moves - Pupils stand on a floor number line, spin a spinner and move forwards/back saying the number sentence.
• Caterpillar Grows - Children build a caterpillar from pom poms/cubes. They make it 1 or 2 longer/1 or 2 shorter.
• Pirate Treasure - A pirate adds 1 or 2 coins/takes 1 or 2 out of a treasure chest. Pupils say how many coins are in the chest.
Varied Fluency
• Q1: Find 1 more, 1 less and 2 more than a number.
• Q2: Decide whether to add or subtract, then complete the number sentence.
Reasoning and Problem Solving
• Q1: Reasoning – spot that Dev has used addition when he should have used subtraction.
• Q2: Problem Solving – find different pairs of numbers where one is 2 more than the other.
Continuous Provision
• Maths area – roll +1, +2, -1 or -2 and change a ten frame.
• Small world area – pirates climb aboard or jump off a pirate ship.
• Construction area – make towers 1 or 2 bricks taller or shorter.
• Malleable area – press number pieces into play dough to add 1 or 2.
• Sand area – add or take away flags on a sandcastle.
• Home corner – teddies join or leave a picnic.
• Music area – tap a drum 1 or 2 more or fewer times.
• Outdoor area – throw or take out beanbags from a basket.
