Door 24 Plus is a math fluency app that harnesses the power of game design to help develop students skills in both fact fluency and computational fluency. It provides targeted practice in the use of basic facts, number sense, and algebraic thinking.
Students will have the chance to play one of two games depending on their level:
Snargg Splatt develops fact fluency
Victor Fixer develops computational fluency
Door 24 Plus is part of i-Ready, an award-winning online program published by Curriculum Associates. Learn more about i-Ready at i-ready.com
Fact Fluency game (Snargg Splatt)
Fact fluency practice with all 4 operations
Options for reviewing facts in an instructional sequence
2-player version for collaborative play
i-Ready users can log in to the app and save their data across devices
Computational Fluency game (Victor Fixer)
Provides practice in computational fluency across five grade levels, from grades 4 8 with content available for students who are working a level behind.
Multiple sets of problems with increasing difficulty so that students slowly work their way up.
Bonus activities require students to find all possible solutions to expand their problem solving skills.
Includes scaffolded hints and Math Review screens to help students when they struggle.

Evaluate square roots and cube roots
Understand and apply properties of integer exponents
Math standards propose a balanced approach to math and stress the goals of conceptual understanding, fluency, and application. Door 24 Plus focuses on establishing a foundation based on fact fluency and then building computational fluency by providing practice that requires students to solve problems using basic facts, number sense, and algebraic thinking.
Being able to automatically recall facts will help students free up working memory and allow them to concentrate on more challenging math tasks. For example, spending time counting on fingers to work out an addition or subtraction problem can be an impediment to working on higher-level math skills. Additionally, by having math fact fluency, students will be more confident which can lead to greater gains later on.
The Principles and Standards for School Mathematics (NCTM 2000) state: Students exhibit computational fluency when they demonstrate flexibility in the computational methods they choose, understand and can explain these methods, and produce accurate answers efficiently.
Door 24 Plus addresses each of the three facets of computational fluency:
Accuracy: Students use number facts, order of operations, and number relationships to create expressions that are equivalent to 24
Efficiency: Students learn to use strategies that are easily practiced such as making tens, recognizing factors of 24, thinking of an expression as a single quantity, understanding relationships between operations, etc.
Flexibility: The Challenge set in every level requires students to find as many expressions as possible that are equivalent to 24 given a particular number set. Students also need to be flexible in choosing an appropriate strategy or strategies based on the problem at hand.
