Number Line, by MLC vs SAM Root

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.

SAM Root makes it easy and fun to learn programming through hands-on robotics! With three progressive coding levels—from graphical blocks to hybrid blocks to Python 3 syntax—you’ll be building real coding skills and controlling robots in no time. MASTER CODING WITH 3 LEARNING LEVELS No coding experience? No problem! SAM Root meets you where you are and grows with your skills: - LEVEL 1: Graphical Blocks – Start with drag-and-drop, graphical blocks to grasp the fundamentals of coding logic—no reading required. - LEVEL 2: Hybrid Blocks – Transition into more advanced coding structure with blocks that blend visuals and coding script. - LEVEL 3: Python Code Blocks – Discover the structure and syntax of professional coding languages with full-text Python 3 code blocks. SEAMLESSLY SWITCH BETWEEN LEVELS Change coding levels anytime with a tap. SAM Root automatically converts your code, so you can match your skill level and learn the professional Python syntax behind each block. CONNECT TO ROOT ROBOTS Pair with a Root coding robot via Bluetooth and bring your programs to life! Control movement, lights, sounds, sensors, and more—while watching your code run in real time. TEST WITH THE BUILT-IN SIMULATOR Use the built-in 3D simulator to test your programs, speed up execution, and try new ideas—all without needing hardware.
