Aims of Presentation
• To give a break down of strategies used when teaching the 4 operations (+,-,x,/).
• To highlight progression of maths throughout Key Stages and how strategies link and develop.
• To give the rationale behind the strategies.
• To explain intervention programs.
• To explain how we make maths ‘real’ and fun in our school.

Key Stage 1 Addition
+ Beadstrings to 20 and 100
+ Counting on from the biggest number
+ Numberline – counting on
+ Addition on an empty numberline
+ Jump 10, To the 10, Over Jumping
+ Number-bonds to 10
+ Partitioning

Key Stage 2 Addition
• Empty number line (ENL) Purpose: To provide pupils with a visual model. It shows the relationship between numbers. It reinforces number order and the process of addition (through jumps). • Partitioning • Column addition Initially simple addition which is extended to carrying numbers when understanding is established.

Early Years Subtraction
- Using a variety of objects—physically removing objects
- Beadstring to 20
- Singing songs
- Verbal problem solving
-Language used: less than, take away
- Smaller group left

Key Stage 1 Subtraction
- Physically solving problems
- Use of number bonds and hearts in love to solve
- Using a beadstring
- Finding the difference by counting on using a numberline
- Numicon

Early Years Multiplication
x Entirely practical based
x Counting on in 2’s
x Repeated addition
Eg: There are 3 plants, each has two leaves, how many leaves are there?

Key Stage 1 Multiplication
x Use of arrays to explain
x Counting on in 2’s, 5’s and 10’s
x Understanding multiplication as: groups of, lots of and sets of
x Solving problems using repeated addition
eg: 5 x 4 = 5+5+5+5 =

Key Stage 1 Division
÷ Understood as sharing
÷ Progresses from doubling/halving to repeated subtraction using Numicon.
÷ Counting back on a numberline
÷ Arrays

Interventions
• Regular assessment – In-class assessment, end of unit assessment, NFER and optional SATS.
• Personalised targets derived from identified gaps in knowledge.
• Assessment for learning
• Numicon
• Rapid Maths

Topic Maths
• Real World context
• Linked to the class topic and is often cross curricular
• “When are we going to do our maths lesson?”
• Open ended tasks
• Independent learning
• Extends the more able
• Fun!
