4th Grade Math Unit 9

Big Idea:

Solve problems involving various units of measurement.

Student Expectations:

Priority TEKS

4.5(D) [Readiness] solve problems related to perimeter and area of rectangles where dimensions are whole numbers

4.8(C) [Readiness] solve problems that deal with measurements of length, intervals of time, liquid volumes, mass, and money using addition, subtraction, multiplication, or division as appropriate

Focus TEKS

4.5(C) [Not Tested] use models to determine the formulas for the perimeter of a rectangle (l+w+l+w or 2l+2w), including the special form for perimeter of a square (4s) and the area of a rectangle (l x w)

4.8(A) [Supporting] identify relative sizes of measurement units within the customary and metric systems

4.8(B) [Supporting] convert measurements within the same measurement system, customary or metric, from a smaller unit into a larger unit or a larger unit into a smaller unit when given other equivalent measures represented in a table

Ongoing TEKS

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;

4.1(F) [Ways to Show] analyze mathematical relationships to connect and communicate mathematical ideas; and

4.1 (G) [Ways to Show] display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication.

Student Learning Targets:

• I will identify and describe relative sizes of measurement units within the customary system.
• I will identify and describe relative sizes of measurement units within the metric system.
• I will solve problems that deal with length, capacity, and mass.
• I will solve problems that involve intervals of time.
• I will solve problems that involve money.
• I will calculate the area of a rectangle when given length and width.
• I will calculate the perimeter of a rectangle when given length and width.
• I will solve for the missing side of a rectangle when given the perimeter or area.
• I will convert units of measurements within the same measurement system.

Essential Questions:

• What is a real world situation where you would use measurement?
• What is the difference between area and perimeter?
• What are some ways you can solve for perimeter?
• What are some ways you can solve for area?
