3rd Grade Math Unit 4

Big Idea:

Represent multiplication facts through a variety of approaches and recalling them with automaticity.

Student Expectations:

Priority TEKS

3.4(E) [Supporting] Represent multiplication facts by using a variety of approaches such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line, and skip counting.

3.4(F) [Supporting] Recall facts to multiply up to 10 by 10 with automaticity and recall the corresponding division facts.

3.6(C) [Readiness] 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.

Focus TEKS

3.4(K) [Readiness] Solve one-step and two-step problems involving multiplication and division within 100 using strategies based on objects; pictorial models, including arrays, area models, and equal groups; properties of operations; or recall of facts.

3.5(B) [Readiness] Represent and solve one and two step multiplication and division problems within 100 using arrays, strip diagrams, and equations.

3.4(D) [Supporting] Determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10.

3.5(C) [Supporting] Describe a multiplication expression as a comparison such as 3 x 24 represents 3 times as much as 24.

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

Ongoing TEKS

3.2(B) [Supporting] Describe the mathematical relationships found in the base-10 place value system through the hundred thousands place.

3.5(E) [Readiness] Represent real-world relationships using number pairs in a table and verbal descriptions.
