08 Addition – Add Together

The Year 1 Addition – Add Together 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

part: A part is one of the groups we put together.

whole: The whole is how many there are when the parts are put together.

plus: Plus means we put the parts together. We use the + symbol.

addition sentence: An addition sentence shows the parts and the whole.

Adult-Led Practical Activities

• Activity 1: Button Part-Whole (links to the Varied Fluency part-whole question)

You will need:

• buttons in two colours and a large part-whole model (or three hoops)

• number cards 0 to 10, plus + and = cards

• interlocking cubes in two colours and two 1 to 5 dot dice

Why not try…

Varied Fluency

• Q1: Adding buttons and completing a part-whole model and addition sentence.

• Q2: Interpret the counters in the ten frame and create an addition sentence from this.

Reasoning and Problem Solving

• Q1: Reasoning – spot the mistake in a number sentence and explain where the parts and the whole belong.

• Q2: Problem Solving - find all the pairs of number cards that add together to equal 8.
