Description

**'Hit me' with fractions!**

By playing Frack Jack, learners get to exercise important critical thinking skills when determining which equivalent parts of a whole can be substituted for others. Learners also learn to closely estimate accumulated parts that may make one whole circle. By removing parts to substitute for other equivalent parts, learners gain understanding in manipulating fractions to meet their goal.

**Curriculum topics**: Fractions, addition, subtraction, equivalent parts, substitution, estimation

**Kit ****includes****: **Idea sheet, 1 deck of Frack Jack playing cards, 1 set of 51 circle foam fractions

**Number served**: 2-4

**Grades:** 2-8

Recommended for ages 7 and up.

Standards:

- 3.NF.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.
(Common Core Mathematics /// Grade 3 /// Number And Operations?Fractions5 /// Develop Understanding Of Fractions As Numbers)

- 3.NF.2. Understand a fraction as a number on the number line; represent fractions on a number line diagram.
(Common Core Mathematics /// Grade 3 /// Number And Operations?Fractions5 /// Develop Understanding Of Fractions As Numbers)

- 3.NF.3. Explain equivalence of fractions in special cases, and compare fractions by reasoning about their size.
(Common Core Mathematics /// Grade 3 /// Number And Operations?Fractions5 /// Develop Understanding Of Fractions As Numbers)

- 3.G.2. Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.
(Common Core Mathematics /// Grade 3 /// Geometry /// Reason With Shapes And Their Attributes)

- 4.NF.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.
(Common Core Mathematics /// Grade 4 /// Number And Operations?Fractions3 /// Extend Understanding Of Fraction Equivalence And Ordering)

- 4.NF.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. Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.
(Common Core Mathematics /// Grade 4 /// Number And Operations?Fractions3 /// Extend Understanding Of Fraction Equivalence And Ordering)

- 4.NF.3. Understand a fraction a/b with a > 1 as a sum of fractions 1/b. a.
(Common Core Mathematics /// Grade 4 /// Number And Operations?Fractions3 /// Build Fractions From Unit Fractions By Applying And Extending Previous Understandings Of Operations On Whole Numbers)

- 5.NF.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. For example, 2/3 + 5/4 = 8/12 + 15/12 = 23/12. (In general, a/b + c/d = (ad + bc)/bd.)
