*** Full use of this app requires an active account for Symphony Math®. If you do not have account information, please contact your school for more information. *** A SIMPLE SOLUTION TO A DIFFICULT PROBLEM Many students struggle with math because they rely on arbitrary memorization techniques to answer specific questions. With this approach, students do not gain a substantive understanding of fundamentals and simply cannot adjust to more sophisticated problem solving. With Symphony Math®, these problems are resolved. Symphony Math® helps students understand mathematics at a conceptual level. Instead of being overwhelmed by numbers, students move at their own speed and learn how math works. Through every stage of Symphony Math®, students gain a strong foundation in underlying principles and become better equipped to take on basic and advanced subjects. Going far beyond rote math drills and practice tests, this special teaching solution illuminates the core of learning and produces confident, more capable students. BUILT IN ASSESSMENT Students take a Fall, Winter, and Spring assessment that quickly identifies at-risk students and helps track growth. A ROBUST INTERVENTION THAT SUPPORTS STUDENTS WHO NEED HELP IN MATH The best practices in developmental psychology and cognitive science are the cornerstones of Symphony Math®. Our uniquely designed delivery methods ensure that students – regardless of learning styles or knowledge levels – fully grasp fundamental mathematical ideas, even for difficult-to-explain and abstract concepts. The result is a solid foundation for acquiring higher math skills, as well as a positive learning experience.

Number Line helps students visualize number sequences and demonstrate strategies for counting, comparing, adding, subtracting, multiplying, and dividing. Choose number lines labelled with whole numbers, fractions, decimals, or negative numbers. Or use a blank number line, with or without tick marks. Describe intervals between points on the line using forward or backward jumps above and below the line. Jumps can be labelled with their values or left blank. Add custom tick marks to the number line to show equivalence or compare number values. Show strategies with drawing and annotation tools. Hide elements of the sequence shown on the number line, which challenges students to use what they know about number relationships and computation to identify those missing elements. This virtual number line is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPads. For more Number Line resources and other apps, visit: www.mathlearningcenter.org/apps FEATURES • Mark the number line with multiples of whole numbers, fractions, or decimals. In addition, set the starting value of the line, including using negative values. • Add and manipulate forward and backward jumps, above or below the line. • Label jump bars, manually or automatically, to show intervals or hide labels altogether. • Add custom tick marks and values to blank number lines. • Hide and reveal numbers on the number line. • Hide and reveal jumps, numbers, and other elements with resizable covers to create your own problems and model strategies. • Use the drawing tools to annotate work and show understanding. • Add equations, expressions, and descriptions with the math text and writing tools. • Share your work by saving an image or providing a share code to others.
