4th Grade Math Unit 3

Big Idea:

Represent and solve multiplication problems with fluency.

Student Expectations:

Priority TEKS

4.4(B) [Supporting] determine products of a number and 10 or 100 using properties of operations and place value understandings

4.4(D) [Supporting] use strategies and algorithms, including the standard algorithm, to multiply up to a four-digit number by a one-digit number and to multiply a two-digit number by a two-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties

4.4(H) [Readiness] solve with fluency one- and two-step problems involving multiplication and division, including interpreting remainders

Focus TEKS

4.4(C) [Supporting] represent the product of 2 two-digit numbers using arrays, area models, or equations, including perfect squares through 15 by 15

4.4(F) [Supporting] use strategies and algorithms, including the standard algorithm, to divide up to a four-digit dividend by a one-digit divisor

Ongoing TEKS

4.4(A) [Readiness] add and subtract whole numbers and decimals to the hundredths place using the standard algorithm

4.1 (A) [Tools to Know] apply mathematics to problems arising in everyday life, society, and the workplace;

4.1(B) [Tools to Know] use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution;

4.1(C) [Tools to Know] select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems;

4.1(D) [Ways to Show] communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate;

4.1(E) [Ways to Show] create and use representations to organize, record, and communicate mathematical ideas;

Student Learning Targets:

• I will solve one and two-step word problems involving multiplication.
• I will multiply a four digit number by a one digit number using strategies and the algorithm.
• I will multiply a two digit by two digit number using strategies and the algorithm.
• I will find products of multiples of 10 and 100 using knowledge of place value.

Essential Questions:

• How are addition and multiplication related?
• What is the pattern of a multiplying a number by 10 or 100?
• Develop a plan to solve a given multi-step problem.
• What strategy did you use to multiply?
• In what way can you determine the operation needed to solve?
