Performance objectives

• Data handling is a very important skill because it helps us to understand information all around us! Imagine trying to decide which flavour of ice cream is most popular with your friends, or knowing which colour is liked by the most people in your class. Data handling helps us collect, organize, and understand this kind of information. In South Africa, understanding data helps us to make informed decisions, from what fruits to buy at the market to understanding weather patterns. We will revise concepts and extend our understanding this week.
• Learning Objectives:
• By the end of the lesson, learners will be able to:
• Collect data using tally marks and organize it into a simple table. (CAPS: Numbers, Operations and Relationships; Data Handling)
• Represent data using pictographs with one-to-one correspondence. (CAPS: Data Handling)

Lesson notes

Data: Data is information! It can be anything like the colours of cars, the number of siblings people have, or the types of pets people own.

Collecting Data: We collect data by asking questions or observing things. A common way to collect data is by using tally marks. Each tally mark represents one item.

For example: | Item | Tally Marks | Number | |-------|-------------|--------| | Apples | ||| || | 5 | | Bananas| ||| | 4 | | Oranges| || | 3 | Each group of five tally marks is drawn as four vertical lines and one diagonal line across them.

Tally Tables: A tally table helps us organize our data neatly. We write down what we are counting (like types of fruit), then use tally marks to count how many of each we have, and finally write the total number.

Pictographs: A pictograph is a way to show data using pictures. Each picture represents one item. It makes the data easy to see and understand. For example, we can represent the same data from the table above using a pictograph: Title: Favorite Fruits | Fruit | Pictograph | |---------|----------------------| | Apples | 🍎 🍎 🍎 🍎 🍎 | | Bananas | 🍌 🍌 🍌 🍌 | | Oranges | 🍊 🍊 🍊 | Key: 🍎 = 1 apple, 🍌 = 1 banana, 🍊 = 1 orange Asking Questions about Data: Once we have our data organized, we can ask and answer questions about it.

For example: "Which fruit is the most popular?", "How many more apples are there than oranges?".

Revision: Number Recognition, Addition, Subtraction, Shape Identification: This week we also revise previously learned material, for example, identifying numbers from 1-20, adding and subtracting within 10, and naming basic shapes (circle, square, triangle, rectangle).

Worked example

Thando: dog

Aisha: cat

Sipho: dog

Zola: bird
