B5 Mathematics · Term 3, Week 10

Data Collection, Organisation, Presentation, Interpretation and Analysis

Lesson notes

Learning Objectives

Indicator: B5.4.1.2.1 - Draw double bar graphs, complete with title, labelled axes, key or legend, to represent data collected (up to 3 pairs of categories of data and use it to solve problems.

By the end of the lesson, learners can:

Identify the components of a double bar graph, including the title, labelled axes, and key or legend.
Draw a double bar graph from a table of paired data (up to 3 pairs of categories) with a title, labelled axes, and a key.
Read and interpret data from a double bar graph to answer questions.
Solve simple problems by comparing two sets of data presented in a double bar graph.
Justify their conclusions by referring to specific bars or values in the graph.

Exemplars (from the NaCCA curriculum)

E.g. 1. Give students data presented in a table on rainfall in mm for two towns to draw a double bar graph complete with title, labelled axes, key January February March April May June Kumasi 5 10 15 20 50 45 Oda 3 10 13 25 40 50

Visible labels, values, and notation include: represent data collected (up to 3 pairs of categories of data and use it to solve problems.; E.g. I. Give students data presented in a table on rainfall in mm for two towns to draw a double bar graph; complete with title, labelled axes, key;.

Visible labels, values, and notation include: 60; 50; E 40; 30; 10; 0; Rainfall in Kumasi and Oda; • Kumasi; Oda; January February; March; April; Months; May; June.

E.g. 2. Give students more paired data presented in a tables. Ask them to study the paired data in the tables and ask them questions based on them. Also ask them to write questions for their friends to read and interpret the data. For instance some questions can be (i) In which subject was Fusena's worse performance? (ii) How many pupils are in the upper primary classes in Presby? (iii) When was the best day for Senasco shop?

Visible labels, values, and notation include: (i) test scores of 2 students; Student; Fusena; Alidu; Maths; 75; 55; English; 60; 70; (ii) enrollment in 2 school in a town; School; P1; P2; Presby; 35; 30; Roman; 45; 50; P3; 40; (iii) Sales of bread in two shops in a week; Shop; Abijak;.

E.g. 3. Ask learners to draw double bar graphs complete with title, labelled axes, key for the paired data presented in the tables on (i) percentage test scores of 2 students; (ii) enrolment in 2 schools in a town; sales of two of bread in two shops in a week; etc.
