We have been using it for three years, sometimes as a primary resource and sometimes as a supplement to another program. Even when choosing another program, we keep the DreamBox subscription as a "go to" when the kids are feeling less motivated for book work.” — Fonda, Parent “DreamBox is awesome! My kiddo loves it and looks forward to playing on it. I love that they are learning so much, and that they think it's a game!” — Jules, Parent “DreamBox helps students understand the background information; making them stronger mathematically, conceptually, and helping them fully understand the material. That’s what I like. They’re walking away with a deeper understanding of math.” — Amber, Teacher “DreamBox allows our teachers to really provide in-the-moment differentiation to reach each student where they are.” — Leia, Principal

*Use your premium Teachley account login to unlock the app.* The sinister Professor Possum makes his return in Subtractimals. In this follow-up app to Addimals, students use subtraction strategies to help Memo, Patooey, and her cousin, Slurp stop his latest evil plan. Subtractimals EDU is the school version of an engaging game that teaches subtraction. The characters once again model strategies that children use to practice solving subtraction problems. Most fluency apps use drill-based approaches, such as digital worksheets, flashcards, and multiple choice. In contrast, Subtractimals focuses on teaching effective math strategies and scaffolds learning to promote conceptual understanding and fact fluency. Designed to support Response to Intervention programs, this app is a great tool for teachers looking to differentiate instruction for students. What are teachers saying?
