Common Core State Standards content

Slice Fractions’ design philosophy is based on the Common Core State Standards and covers the following concepts.

  • CCSS.Math.Content.2.G.A.2 Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
  • CCSS.Math.Content.2.G.A.3 Partition circles and rectangles into two, three, or four equal shares […]. Recognize that equal shares of identical wholes need not have the same shape.
  • CCSS.Math.Content.3.NF.A.1 Understand a fraction 1/b as the quantity formed by 1 part when a whole is partitioned into b equal parts; understand a fraction a/b as the quantity formed by a parts of size 1/b.
  • CCSS.Math.Content.3.NF.A.3 Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
  • CCSS.Math.Content.4.NF.A.1 Explain why a fraction a/b is equivalent to a fraction (n × a)/(n × b) by using visual fraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.
  • CCSS.Math.Content.4.NF.A.2 Compare two fractions with different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2.[…] Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
  • CCSS.Math.Content.4.NF.B.3 Understand a fraction a/b with a > 1 as a sum of fractions 1/b.

Universal and accessible

Reading has its own set of challenges and is a common obstacle to learning math. Slice Fractions innovates by not using a single word to teach fractions. It is an intuitive and enjoyable experience for kids.

University partnership
Ululab takes the educational qualities of its games very seriously. Learning experts at the Université du Québec à Montréal review the game regularly. Our partnership allows us to validate the pedagogical approach during development and to have a third party measure the learning impact of Slice Fractions.
A real game, not a thinly veiled quiz
How about a game that offers more than quizzes or gamified school activities? Slice Fractions is a real problem solving game that triggers deep thinking on fundamental math concepts.
