B6 Mathematics · Term 3 Week 8: Data Collection, Organization, Presentation, Interpretation and Analysis

Lesson notes

Learning Objectives

Indicator: B6.4.1.1.3

By the end of the lesson, learners can:

Apply the common attributes of a line graph (title, labelled axes, and consistent intervals) to draw a line graph from a given table of values.
Plot data points accurately from a table and join them with straight line segments in sequence.
Read values from a line graph to answer questions such as “What is the value at a given point?” and “Between which points does the value increase or decrease?”
Interpret the overall trend shown by a line graph (rising, falling, constant, or changing direction) and draw a conclusion based on that trend.
Write their own questions based on a drawn line graph for a friend to answer, justifying their own interpretations.

Curriculum details

Strand: Data (Strand 4)
Sub-strand: Data Collection, Organization, Presentation, Interpretation and Analysis (4.1)
Content standard: B6.4.1.1 - Create, label, and interpret line graphs to draw conclusions.
Indicator: B6.4.1.1.3 - Apply understanding of how to create a line graph by using a given table of values (or set of data) to draw a line graph and answer questions based on them to interpret and draw conclusions
Suggested placement: Term 3, Week 8 (Week 32 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

E.g. 1. Ask learners to draw more line graphs for given data values by determining the common attributes (title, axes and intervals) and pose, as well as answer, questions based on them to interpret the line graphs to draw conclusions (i) Progress of plant's growth recorded by Kofi over a week Days (d) 1 2 3 4 5 6 7 8 Height (h) (cm) 5 6.5 8 9.5 11 12.5 14 15.5 (ii) Cost of boxed lunches for students on a field trip.

For instance, after what time will the water temperature reach 70oC? What is the water temperature after 5 minutes?
E.g. 3. Ask learners to write questions for their friends to read and interpret the line graphs The document numbers this indicator's exemplars 1 then 3; there is no E.g. 2.
