3rd Grade Math Unit 5

Big Idea:

Solve division problems using strategies related to multiplication.

Student Expectations:

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.

3.4(H) [Supporting] Determine the number of objects in each group when a set of objects is partitioned into equal shares or a set of objects is shared equally.

3.4(I) [Supporting] Determine if a number is even or odd using divisibility rules.

3.4(J) [Supporting] Determine a quotient using the relationship between multiplication and division.

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

3.5(D) [Supporting] Determine the unknown whole number in a multiplication or division equation relating three whole numbers when the unknown is either a missing factor or product.

Ongoing TEKS

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

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