Stage 1: informal acting

Represent reality with daily life manipulatives.
For children it is important to start learning mathematics in real-life situations. For example, they will count everything they see: fruit, dolls, pens, scissors, balloons, etc.

Stage 2: Represent - concrete

Represent reality with use of realistic models.
For example, represent a number of concrete items like pens or balloons, by sliding the same number of beads on a counting frame. Stimulate the 1 to 1 correspondence and link the action of moving beads and naming the values shown.

Stage 3: Represent - abstract

Represent reality with use of abstract models.
Stimulate children, for example, to recognise and to use the 5 and 10's as anchors when they are counting. By using these structures, representing a number of items can be done more easy and efficient than one by one counting.

Stage 4: Formal acting

Perform formal operations and explain verbally.
Help children to use mental models. For example, instead of really sliding the beads on a counting frame, children learn to make the transition to abstract reasoning by only looking at it.
