### Product Overview

According 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."

Following the work of lower elementary number lines these activities incorporate association of fractional parts, and decimals on a number line. More advanced work follows negative snake game with using a positive and negative number line to work on absolute values.

This curriculum makes use of the "empty number line."

The "empty number line" is an instructional method for teaching mathematics that was developed in the Netherlands in the 90s. It is a powerful teaching tool that aids students in visualizing and understanding number concepts and operations.

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. The line represents a continuum of numbers, and students mark relevant numbers on it as they solve problems.

The concept emphasizes mental calculation. 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. 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).

The empty number line encourages a deep understanding of number relationships and operations. It helps students to become flexible, resourceful, and confident in their use of numbers and calculations.

Number lines are printed on our specialty vinyl so there is no need to laminate them.
