This page provides examples of Counting Centers aligned with Add+Vanced Math Recovery AVMR and the Early Childhood Assessment in Mathematics (ECAM) and the Numberation Continuum. Fluency with basic multiplication facts (0x0 - 9x9) and related division facts is considered foundational for further advancement in mathematics. These facts form the basis for learning multi-digit multiplication and division, area, fractions, percentages, volume, ratios, and decimals. This page provides examples of division centers that can be used to support the development of multiplication fluency. These centers can be used by teachers or parents to support students' progress within a stage, or to facilitate movement to the next stage on the division continuum. There are also Counting Workstations, Numeration Workstations , Addition and Subtraction Workstations, and Multiplication Workstations. For more information on using centers as an ongoing routine to develop math fluency in 3rd thrpugh 5th grade classrooms see here.
Stage 1.1
These students can share small amounts equally and divide a collection into groups of a given number. They are able to build arrays and use skip counting to solve simple division problems.
Next Steps: Fluently divide by 1, 5, and 10 within 100, using strategies such as the relationship between multiplication and division (e.g. knowing that 8 x 5 = 40, one knows 40 divided by 5 equals 8), or properties of operations.

Stage 1.2
These students demonstrate fluency when dividing by 1, 5 and 10 within 100.
Next Steps: Fluently divide by 2, 4, and 8 within 100, using thinking strategies (e.g. halving to divide an even 2-digit number by 2, 4, or 8), the relationship between multiplication and division, and properties of operations.

Stage 1.3
These students demonstrate fluency when dividing by 2, 4, and 8 within 100.
Next Steps: Fluently divide by 3, 6, 7, and 9 within 100, using strategies such as the relationship between multiplication and division, or properties of operations.
Possible workstations :
Stage 1.4
These students demonstrate fluency when dividing within 100.
Next Steps:
- Continue to regularly practice division strategies in order to know from memory all division facts within 100
- Solve problems involving extended division facts within 100 (e.g. 75 ÷ 5)
Possible workstations :
Stage 2.1
