This page provides examples of Counting Workstations aligned with the Early Childhood Assessment in Mathematics (ECAM) and the Numeration Continuum. These workstations can be used by teachers or parents to support students' progress within a stage, or to facilitate movement to the next stage on the ECAM continuum. There are also Counting Workstations, Numeration Workstations, Multiplication Workstations, and Division Workstations . For more information on using centers as an ongoing routine to develop math fluency in Kindergarten, 1st and 2nd grade classrooms see here.
Stage A: AVMR : Structuring Level 0 to 1 (structuring to 5), Add&Sub Construct 0 to 1
These children are just beginning to understand the concepts of putting small collections together, or taking a small amount from a collection. They are not yet successful in finding sums or differences.
Next Steps:
- Successfully put two small collections together and find the sum
- Find the difference after taking a small amount from a collection

Stage B: AVMR Structuring Level 1 to 2 (intermediate structures to 10), Add&Sub Construct 1 to 2
These children can successfully put two small collections together and find the sum. They can also find the difference after taking a small amount from a collection. They need to fully model, and count from one by ones to find their answers.
Next Steps:
- Begin to use ‘short-cuts’ to add two small collections, or to take a small amount from a collection (e.g.count on to find a sum, or count back, count down to, or count up from to find a difference)

Stage C: AVMR Structuring Level 2 to 3 Facile structures to 10, or expanding the range Level 3 to 5 , Add&Sub Construct 3 to 4
These children are beginning to use short-cuts to add two small collections, or to take a small amount from a collection. They only need part of a model, and either count on to find a sum, or count back, count down to, or count up from to find a difference.
Next Steps:
- Begin to use 'simpler' thinking strategies to add and subtract (adding one or zero, using doubles, turning around the addends, sums to ten, or adding ten).

Stage D: AVMR Structuring Level 3 to 5 (Facile structures to 20), Add&Sub Construct 4 to 5
These children are able to add and subtract small amounts using 'simpler' thinking strategies (adding one or zero, using doubles, ‘turning around’ the addends, sums to ten, adding ten). They are able to mentally add and subtract small numbers without making a model.
Next Steps:
- Use later thinking strategies (fact families, extending to larger numbers, near doubles, make to ten, adding nine).
Stage E: AVMR Structuring Level 3 to 5 (Facile structures to 20), Add&Sub Construct 4 to 5
These children are able to extend their thinking strategies to include larger numbers, and more difficult calculations with small numbers. They add and subtract mentally, using thinking strategies such as fact families, ‘near doubles’, build to ten, and adding nine.
