![]() It helps students to become flexible, resourceful, and confident in their use of numbers and calculations. The empty number line encourages a deep understanding of number relationships and operations. ![]() For example, when solving an addition or subtraction problem, students can use the number line to show jumps forward (for addition) or jumps backward (for subtraction). Students use the empty number line to demonstrate and articulate their strategies and reasoning, often beginning with larger, easier jumps, and then making smaller, precise jumps as needed. The concept emphasizes mental calculation. The line represents a continuum of numbers, and students mark relevant numbers on it as they solve problems. In contrast to the traditional number line, which has numbers already placed along the line, the empty number line is initially blank, allowing students to add their own numbers. It is a powerful teaching tool that aids students in visualizing and understanding number concepts and operations. The "empty number line" is an instructional method for teaching mathematics that was developed in the Netherlands in the 90s. This curriculum makes use of the "empty number line." All four task cards meet common core suggestions for lower elementary mathematics. This material is ready for you to put on the shelf.Īccording to the latest research on how the brain learns math "by the age of 6 children have developed a mental number line that gives them central conceptual structure for whole numbers." Extending the basic number line, these activities place scale, fractions, and money on a number line.
