The Number Line Digi-Tool is an interactive virtual number line designed for exploring counting, addition, subtraction, and fractions. This versatile tool is ideal for teaching these mathematical concepts through visual representation, fostering engagement and deeper understanding.

 

Key Features of the Number Line:

1. Customisable Number Range: Set the starting and ending numbers between -900 and 999 to suit different learning needs.
2. Whole Numbers, Decimals, and Fractions: Step sizes can be whole numbers, decimals (tenths), or fractions (halves, thirds, quarters) to align with your lesson focus.
3. Interactive Number Span Adjustments: Easily add, move, and resize number spans for tailored teaching experiences.
4. Hide/Reveal Numbers: Conceal all or some numbers to create quizzes or encourage problem-solving.
5. Quick Reset: Use the bin icon to delete a specific span or the refresh icon to reset the number line entirely.

   

How to Use the Number Line:

1. Set Your Range

1. 1. Define your start and end numbers within the range of -900 to 999.
   2. Choose your step size: whole numbers, decimals (tenths), or fractions (halves, thirds, or quarters).
   3. Click the refresh button to apply your changes.

2. Add and Adjust Number Spans

1. 1. Click the number span button to add a span to the number line (the default length is 5 steps).
   2. Drag the span to move it, or use the blue dots at each end to resize.
   3. Customise the span's visibility:
      1. Click the step icon (turns green) to hide the step count.
      2. Click the number box icon (turns green) to hide the start and end numbers.

   

Interactive Activities for Classroom Engagement:

1. Counting Practice
   1. Expand, contract, and move number spans for interactive counting exercises, ideal for younger students.
2. Addition and Subtraction Sums
   1. Select the x+y icon to visualise sums dynamically as spans grow to represent the total.
3. Problem-Solving with Missing Values
   1. Click the eye icon to hide all values on the spans, replacing them with question marks.
   2. Reveal specific values by clicking the question marks for targeted problem-solving tasks.
4. Teaching Fractions and Decimals
   1. Set the step size to halves, thirds, quarters, or tenths to provide hands-on lessons that make abstract concepts concrete.
