Objectives for this lesson:
1.
Given a set of raw data, students will classify, organize, and represent the data using pictographs and bar graphs with at least 80% accuracy.
2.
Given completed pictographs and block graphs, students will interpret the data and use the analyzed information to solve problems and draw conclusions with at least 80% accuracy.
3.
During group data-handling activities, students will show interest and cooperation when organizing and representing data by actively participating and contributing ideas to the group.
Important terms to remember
Pictograph
A pictograph is a type of graph that uses pictures or symbols to represent data. Each picture stands for a certain number.
A pictograph is a graph that uses small pictures instead of bars.
Each picture stands for a number.
👉 Example:
If 1 smiley face 😊 stands for 5 students,
and you see 3 smiley faces,
that means 3 × 5 = 15 students.
So pictographs are like counting pictures instead of numbers!
Bar graph
A bar graph is a type of chart that uses rectangular bars to show and compare amounts of data. The length or height of each bar represents the value.
A bar graph is a picture that uses bars to show numbers.
The taller (or longer) the bar, the bigger the number.
👉 Example:
If 10 students like apples and 5 like oranges, the apple bar will be taller than the orange bar.
Think of it as a race between bars — the tallest one wins! 🏁
