Texas Grade 3 math standards

3.3(A) Represent fractions greater than zero and less than or equal to one with denominators of 2, 3, 4, 6 and 8 using concrete objects and pictorial models, including strip diagrams and number lines.

Lessons: Fair Shares: Fractions and Decimals (Is half always the same size?, Where does three-quarters stand?)

3.3(C) Explain that the unit fraction 1/b represents the quantity formed by one part of a whole that has been partitioned into b equal parts.

Lessons: Fair Shares: Fractions and Decimals (Is half always the same size?)

3.3(D) Compose and decompose a fraction a/b with a numerator greater than zero and less than or equal to b as a sum of parts 1/b.

Lessons: Fair Shares: Fractions and Decimals (Which recipe makes more?)

3.3(F) Represent equivalent fractions with denominators of 2, 3, 4, 6 and 8 using a variety of objects and pictorial models, including number lines.

Lessons: Fair Shares: Fractions and Decimals (Where does three-quarters stand?)

3.3(G) Explain that two fractions are equivalent if and only if they are both represented by the same point on the number line or represent the same portion of a same size whole for an area model.

Lessons: Fair Shares: Fractions and Decimals (Where does three-quarters stand?)

3.3(H) Compare two fractions having the same numerator or denominator in problems by reasoning about their sizes and justifying the conclusion using symbols, words, objects and pictorial models.

Lessons: Fair Shares: Fractions and Decimals (Is half always the same size?)

3.6(C) Determine the area of rectangles with whole-number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row.

Lessons: Fence It, Fill It: Area and Perimeter (Which mat is the biggest?, Does the same fence always hold the same garden?, Can the same rug need more edging?)

3.6(D) Decompose composite figures formed by rectangles into non-overlapping rectangles to determine the area of the original figure using the additive property of area.

Lessons: Fence It, Fill It: Area and Perimeter (How much turf for an L-shaped playground?)

3.7(B) Determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems.

Lessons: Fence It, Fill It: Area and Perimeter (Does the same fence always hold the same garden?, How much turf for an L-shaped playground?)

3.7(C) Determine the solutions to problems involving addition and subtraction of time intervals in minutes using pictorial models or tools. Students solve elapsed-time problems from their own school day.
