Unit 3

Extend understanding of fraction equivalence and ordering.

MGSE4.NF.1 (Fraction a/b = (n x a)/ (n x b)

K1: I can identify equivalent fractions with unlike denominators (2, 3, 4, 5, 6, 8, 10, 12, 100)

R1: I can explain why a/b is equal to (n x a)/ (n x b) using fraction models.

R2: I can explain that the number and size of the parts differ in the two fractions but they are the same size (equivalent).

R3: I can use visual fraction models to show why fractions are equivalent.

R4: I can create equivalent fractions using fraction models and explain why they are called equivalent.

MGSE4.NF.2 (Compare fractions)

K1: I can compare fractions using greater than, less than, or equal to other fractions. Denominators of 2, 3, 4, 5, 6, 8, 10, 12 and 100).

K2: I can compare fractions using symbols. (<, >, =). (Denominators of 2, 3, 4, 5, 6, 8, 10, 12 and 100).

K3: I can use benchmark fractions such as 1⁄2 to compare fractions.

K4: I can compare fractions using parts of the same whole.

R1: I can compare two fractions with different numerators using a benchmark fraction such as 1⁄2.

R2: I can compare two fractions with different denominators by creating common denominators.

R3: I can compare two fractions with different denominators by comparing to a benchmark fraction such as 1⁄2.

R4: I can justify the results of a comparison of two fractions using a visual fraction model.

Use the four operations with whole numbers to solve problems.

MGSE4.OA.3 (Multi-step word problems with all operations)

K1: I can divide whole numbers with and without remainders.

R1: I can write equations to represent multi-step word problems with variables. That means a letter stands for the unknown quantity or number.

R2: I can interpret multi-step word problems (with and without remainders) and choose the correct operation to solve.

R3: I can determine whether my answer is reasonable using mental math, estimation strategies, and rounding.
