Objectives for this lesson:
1.
Given a set of data, students will classify, organize, and represent the data using tally charts and frequency tables with at least 80% accuracy.
2.
Given completed tally charts and frequency tables, 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
Tally Chart
A tally chart uses tally marks to record and count data.
A tally chart helps us count easily by making lines.
Every five lines are grouped together.
👉 Example:
|||| = 4
🧠 Think:
“Lines help me count.”
Frequency Table
A frequency table is a table that shows how often each value or item appears in a set of data.
A frequency table helps us count and organize information.
It tells us how many times something happens.
👉 Example:
If you ask students their favorite fruit, a frequency table can show how many students chose apples, bananas, or oranges.
🧠 Easy way to remember:
“Frequency means how often.”
Item Frequency
Apple 5
Banana 3
Orange 2
This table shows:
-
Apples were chosen 5 times
-
Bananas were chosen 3 times
-
Oranges were chosen 2 times
Mode
The mode is the value that appears most often in a data set.
The mode is the answer that shows up the most.
👉 Example:
Numbers: 2, 3, 3, 4, 5
The mode is 3 because it appears the most.
🧠 Think:
“Which one wins?”

How to work together:
-
Work in groups of three.
-
Talk about each problem before writing the answer.
-
One person types, another checks, and another explains the steps.
-
Show working for every question.
