Number Line, by MLC vs Design Squad Maker

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.

DESIGN SQUAD MAKER APP FEATURES - Create unlimited design projects - Add sketches, photos, and notes - Save progress in an editable portfolio - Watch animated videos explaining the engineering design process - Walk through each step of the design process with a friendly host - Use tips and reflection questions throughout to support children's learning - Check out example project ideas - Find ideas for families to work together - Try quick activities to supplement design projects at home - Use at home and as part of Design Squad Maker workshops around the country - Aligned with STEM curriculum concepts - Co-developed with researchers and families - No in-app purchases - No advertising The Design Squad Maker app was rigorously researched and developed for use at home and in maker space settings. Its open-ended, hands-on approach gives kids control over their own learning, encouraging them to identify problems that matter to them and develop solutions. In addition, when kids solve problems, they learn STEM concepts, practice thinking critically and creatively, gain experience using tools and materials, and learn perseverance when things don’t go as planned. ABOUT DESIGN SQUAD MAKER This app was created as part of Design Squad Maker, a program that engages children and their caregivers in the engineering design process in museums, community maker spaces, and at home. Together, kids ages 8–11 and their caregivers come up with problems that they want to solve, brainstorm solutions, build prototypes, and test them to see how they work. They experience the same steps that engineers use to solve real-world problems.
