The Delta Math RtI Program was developed to help educators identify students not ready to learn current math standards.
In 2007, the Ottawa Area ISD began developing screening and reporting tools to support the implementation of math RtI for its local schools. Soon after, schools in other regions chose to use Delta Math online readiness screeners, data reports and other program resources to meet their needs.
In 2010, Alt+Shift (formerly known as the Michigan's Integrated Mathematics Initiative) identified Delta Math as a promising practice. This added support helped the OAISD to build leadership capacity to support the implementation of Delta Math throughout the State of Michigan.
In 2014, Alt+Shift collaboration focused on the development of Tier 2 and Tier 3 intervention lessons for each Delta Math Readiness and Tier 3 standard.
In 2020, support shifted to break down barriers for students learning at home. Resources were developed to support screening students and using intervention lessons at home. Free online resources are also being identified to include virtual manipulatives and online practice for each Delta Math Readiness and Tier 3 standard.
The Ottawa Area ISD and Alt+Shift would like to thank the following regional service agencies for the feedback and support provided by their consultants: Allegan AESA, Alpena-Montmorency-Alcona ISD, Ann Arbor Public Schools, Bay-Arenac ISD, Berrien RESA, Eaton RESA, Gratiot-Isabella RESD, Huron ISD, Ingham ISD, Jackson County ISD, Kalamazoo RESA, Lenawee ISD, Oakland Schools, St. Joseph County ISD, and Northwest Education Services.
