Unit 8 Data Analysis
Students will independently use their learning to …
Collect, organize, display, and interpret data in order to answer questions and make predictions.
Students will understand that…
Organized data allows us to answer questions and to make inferences and predictions based on that data.
The same data can be represented in more than one way.
Students will keep considering …
How can I use my data to answer questions and make predictions?
What is another way to display my data?
Students will know …
organizing data makes it easier to see patterns.
data can be sorted in different ways.
pictographs and bar graphs represent data.
the length of a bar in a bar graph and pictures in a pictograph represents the number of data points.
Students will be skilled at …
interpreting information in a pictograph and bar graph.
using pictographs and bar graphs to organize data
organizing a collection of data with up to four categories - look at K & 1 wording
drawing conclusions and making predictions from information from graphs.
writing and solving one-step addition and subtraction word problems using data represented in pictographs and bar graphs
applying the mathematical process standards.
Standards
2.1 The student uses mathematical processes to acquire and demonstrate mathematical understanding.
(A) apply mathematics to problems arising in everyday life, society, and the workplace;
(B) 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;
(C) 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;
(D) communicate mathematical ideas, reasoning, and their implications using multiple representations, including symbols, diagrams, graphs, and language as appropriate; (E) create and use representations to organize, record, and communicate mathematical ideas;
(F) analyze mathematical relationships to connect and communicate mathematical ideas; and
(G) display, explain, and justify mathematical ideas and arguments using precise mathematical language in written or oral communication.
2.10 The student applies mathematical process standards to organize data to make it useful for interpreting information and solving problems.
(A) explain that the length of a bar in a bar graph or the number of pictures in a pictograph represents the number of data points for a given category
(B) organize a collection of data with up to four categories using pictographs and bar graphs with intervals of one or more
(C) write and solve one-step word problems involving addition or subtraction using data represented within pictographs and bar graphs with intervals of one
(D) draw conclusions and make predictions from information in a graph
