goodbye pizza pies, Hello Number lines

Think back to your childhood. You’re in 3rd grade, and you are starting a new unit called fractions. What are the images that come to mind? Pieces of a pie? Pizza? This is not how children today are learning about fractions.

Leading researchers and mathematics experts promote using the number line (as opposed to parts of a circle) as a better way to teach fractions because number lines and bar representations help students develop a stronger understanding of how fractions relate to whole numbers. Teachley Fractions games: Fractions Boost, Boost 2, and Fractionators help make learning fractions using the number line engaging and easier to understand.

Fractions Boost EDU

Fractions Boost EDU

Clearly see the meaning of the numerator and denominator.

My students LOVE Fractions Boost; they are super engaged and excited to play

Educational Apps Designed for Thinking

So MUCH more than a worksheet

Teachley Fractions helps students explore the meaning of the numerator and the denominator in engaging 3D game worlds.

STRONG Visual Models To Support Learning

Children who struggle fail to see how fractions relate to whole numbers. That’s why our games make these connections explicit, helping students see where fractions fit on the number line:

Easily see which students are struggling and get intervention lesson support.


Aligned with Common Core and other state standards

Fractions Boost, Boost 2, and Fractionators address most of the 3rd - 5th grade Common Core and other state fractions standards, including:

Understand a fraction as a number on the number line; represent fractions on a number line diagram.

Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100. For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.

Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
