VIRTUAL TOOLS FOR THE MATH CLASSROOM
Stepping Stones 2.0: Comprehensive Mathematics– from ORIGO Education integrates print and digital resources to give teachers flexibility in how they teach K-6 math. SS 2.0 is loaded with additional practice, effective strategies, visual models, and teacher supports. Slatecast lets the teacher broadcast a resource onto the class whiteboard to emphasize or reteach a concept. Kathy Beach, a teacher in North Thurston Public Schools, says about State cast, “What a great way to practice facts and have everyone on the computer.”
Geometry Pad– This virtual graph paper allows students to draw shapes, charts, and other geometric features. Students can change the properties of shapes, zoom in, save their work and add written notes on the side. Geometry Pad is a great application that can be used with students of any age and across mathematical disciplines.
Pattern Shapes– Understanding the properties of shapes, fractions and creating precise figures is easy with Pattern Shapes. Students can use the virtual protractor to measure angles, change the dimensions and color of forms and annotate answers. It is ideal for elementary and middle school students, and the bright colored shapes can inspire creative design.
Globaloria– Learning math through games is a great educational tool. Globaloria allows students to create games that test STEM subjects. With a gallery full of games, students can explore creations that were made by their peers. This application aims to promote STEM subjects on a global level through games and social networking.
MathsPlayground– This collection of math-based games is perfect for younger students. Aligned with Common Core standards the games are separated by grade and topic. Students will enjoy learning while playing interesting games. The games test timetables, fractions, and other mathematical concepts. Combining education with easy to play games is what makes MathsPlayground ideal for young students.
FluidMath– FluidMath is the first “pen-centric “platform that works on iPads and interactive whiteboards. Students and teachers can write, in their own handwriting, as they solve problems and engage with difficult concepts. FluidMath has won many awards, and its many features make it a great tool for both teachers and students in any math classroom.
GetTheMath– The aim of this tool is to relate algebra to the real world. Through topics like “Math in Music” and “Math in Fashion,” students can learn how math is an integral part of everyday life. There are videos, exercises and other ways that students can engage with algebra in its real world setting. GetTheMath is an excellent way to combine theory with application.
Dragon Box– This learner-based approach to math claims that 83% of children learn the basics of algebra in an hour. Through interactive games and explanations, students as young as five are introduced to algebra and how variables work. Students have no idea they are engaging with academic content, and the graphics are colorful and cute.
Academy of Math– Aimed at children struggling with math in school, Academy of Math is a comprehensive tool that helps students get results. Videos and ongoing assessments tools put students in the driver’s seat of their own education.

MATH SKILLS PRACTICE
A number of math apps and online tools can help students develop the necessary foundational understanding of arithmetic operations they’ll need as a baseline for more challenging math problems later on, math teachers told us.
To help younger students practice skills like counting, addition, and subtraction, Ashley Blackwelder, an elementary STEAM coordinator in South Carolina, highly recommends Moose Math, a free app for iPhones and iPads. In Moose Math, students play math games that earn them points to help build a town. Blackwelder says the format is easy for kids to navigate and great for short attention spans.
Curriculum and instructional designer Cassie Tabrizi recommended Happy Numbers (pre-K–grade 5), a subscription-based website ($14.50 per student or $1,450 per site for first-time schools) that breaks down mathematical equations to help students build understanding of higher-order math concepts. To use it, students transform into a dinosaur character and solve math problems to hatch dinosaur eggs. Tabrizi said that the website is helpful, but she recommends using it in moderation: It can feel tedious for students if they practice longer than 10 minutes a day.
Students fight monsters in the persona of a wizard in Prodigy (grades 1–8), a free game-based website (also available as an app for iPhone, iPad, iPod Touch, and Android). Prodigy is loved by kids, but less so by educators because it is more play based. Brittney Paige, a fifth-grade teacher in Seattle, says that even though it is more of a game, she likes that it automatically targets math concepts that students struggled with in its preassessment and tracks how much progress they make on target areas. Most teachers offer Prodigy as an option for students if they finish an assignment early.

Zearn (grades 1–5), a free, self-paced, web-based program aligned with Eureka Math—a free pre-K through 12 math curriculum—starts a typical lesson with fun warm-up activities, like adding up how many apples a cartoon fox eats, to engage students. As they work through the program, students complete timed arithmetic problems, watch instructional videos on new concepts, and solve practice problems. Shannon McGrath, an instructional coach in Western Springs, Illinois, says that Zearn is good “high-level, conceptual practice” and gives good feedback for both teachers and students, but can sometimes progress too slowly for kids who master concepts quickly.
Conclusion
Online tools are valuable aids for teachers to fully grasp their math classes online. It’s especially ideal for those who are introverted, or simply need extra support in teaching various subjects.
