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 represent data in a frequency table.
• I will represent data in a dot plot.
• I will represent data in a stem and leaf plot
• I will compare and contrast fixed and variable expenses.
