Covered concepts (Common Core)

Slice Fractions 2 covers the following concepts:

  • Part-whole partitioning
  • Numerator / Denominator notation
  • Fraction equivalence
  • Fraction multiplication
  • Finding the common denominator
  • Fractions bigger than 1
  • Common Core State Standards (listed underneath)

Slice Fractions 2 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.
  • CCSS.Math.Content.4.NF.B.4 Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.
  • CCSS.Math.Content.5.NF.A.1 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.
  • CCSS.Math.Content.5.NF.B.3 Interpret a fraction as division of the numerator by the denominator (a/b = a ÷ b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem.

Universal and accessible

Reading has its own set of challenges and is a common obstacle to learning math. Slice Fractions 2 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 2.
