## What is Number Intervention?

Number Intervention is a systematic method of teaching your student or child numbers and counting by using  proven techniques with Incremental Rehearsal. This application is designed by Kindergarten and First Grade Educators at top elementary schools who have effectively used these techniques to teach many students as part of core curriculum. Now your student or child can leverage our experience to master numbers and counting to build a strong foundation for match and problem solving.

This application allows you to complete comprehensive assessments of your students' abilities in identifying numbers and counting with 10-frame, tally marks, dice, fingers and objects. After completing assessments, you can focus interventions by selecting nine known numbers and one unknown for the student. Through incremental rehearsal, known numbers are reinforced while those not yet known are mastered. These techniques have been proven to work in many classroom and home settings. 

This application guides you through  interventions by presenting numbers or counting cards in the following order, where Z is unknown and A through I are known by the student:

Z
A, Z
A, B, Z
A, B, C, Z
A, B, C, D, Z
A, B, C, D, E, Z
A, B, C, D, E, F, Z
A, B, C, D, E, F, G, Z
A, B, C, D, E, F, G, H, Z
A, B, C, D, E, F, G, H, I, Z

For each interaction in assessments or interventions, the facilitator records whether the student knows the number or not. The application tracks each and every assessment, automatically recording proficiency when the student reaches 80% for the number or marking as unknown if proficiency drops below the 80% threshold. 

Detailed reports show the following:
- Percentage known by category and each number
- Count of numbers learned by week
- Charting of numbers learned by week compared to goal
- Email progress, detailed results and charts

We hope this offering increases your students' abilities in mastering numbers and counting. We gladly accept feedback and strive to provide the best products for you and those wanting to teach and learn.
