Mathematics - Grade 3

 

 

 

 

Representations and Ordering

 

The learner will:

 

Understand place value and the base-ten number system.

Use cardinal and ordinal numbers appropriately.

Recognize and explain the concept of odd and even numbers.

Describe parts of a set using ½, 1/3, and ¼

Represent, order, label and compare unit fractions using concrete materials.

Describe, represent, order, and compare whole numbers to demonstrate an understanding of the base-ten number system.

Recognize equivalent representations of whole numbers and generate them by composing and decomposing numbers (expanded form).

Judge the size of fractions using models, benchmarks and equivalent forms.

Represent, order, label and compare familiar fractions.

Recognize and generate equivalent forms of familiar fractions.

Explore and discuss uses of decimals in regard to money.

Computation, Operations, Estimation, and Properties

 

The learner will:

 

 Solve two-step addition and subtraction number sentences and word problems including regrouping.

Demonstrate the relationship between addition and subtraction and multiplication and division.

Explore multiplication and division through equal grouping and equal sharing of objects.

Connect repeated addition to multiplication.

Demonstrate fluency with basic addition, subtraction, and multiplication facts.

Identify and use relationships between and among properties of operations.

Apply knowledge of basic multiplication facts (0-10) to related facts (e.g. 3x4=12; 30x4= 120).

Estimate sums and differences of one or two-digit numbers.

Develop and use strategies to estimate (when appropriate) the results of whole-number computations to judge the reasonableness of such results.
