Exploration on the Number Line
This game is designed to improve your maths skills by estimating correctly on the number line.
This game is suitable for the 6th and 7th grade maths curriculum but is also enjoyable for other age groups.
Estimating rational numbers on a number line is a gateway to the magical world of mathematics. This skill not only enables students to understand the relationship between numbers but also develops problem-solving, comparison, and analytical thinking skills.
Being able to see how close a rational number is to a whole number is fundamental to understanding the concepts of magnitude and ratio. The number line makes these abstract concepts concrete, allowing students to relate mathematics to everyday life. For example, when you eat 3/4 of a pizza, visualizing this ratio on a number line makes it easier to understand concepts such as proportion and measurement.
The activity we have prepared guides children to discover the location of rational numbers on the number line and better to understand the cornerstones of mathematics on this journey. Are you ready to transform the abstract language of mathematics into a concrete and understandable world? Let's get started!

How to Play
Basic Rules:
The user makes an estimation on the number line.
He/she presses the ‘Check’ button to check his/her estimation.
If it is in the correct interval, +3 points are added, if it is completed before the time runs out, one fifth of the remaining time is added as points. If it is close, it gets +1 point and if it is completed before the end of the time, one fifth of the remaining time is added as points. If he/she estimated far away, he/she gets no points.
Feedback:
Correct: Correct estimation.
Almost you are very close: You are close.
Maybe next time: Wrong estimation, try again.
Use the ‘New Rational Number’ button to create a new rational number.
Functions of the buttons:
‘Check": Evaluates the estimate.
‘New Rational Number": Starts a new Rational Number.
Number Line Usage:
Estimations are made with a point that can be dragged on the number line.
Mathematical Context
Content:
