1. Data Collection:
   • Data collection is about gathering information or counting different things.
   • For example, count how many green balls and red balls you have.
2. Arranging Data:
   • Once you have collected data, you can arrange it in order.
   • For example, you can put the data in a list, from smallest to largest, or from largest to smallest.
3. Comparing Data:
   • Look at the data you collected and compare it.
   • For example, if you have counted green and red balls, you can say:
     • “Green balls are more than red balls” or
     • “Red balls are less than green balls.”
4. Sorting Data into Groups:
   • You can sort data into groups.
   • For example, if you counted boys and girls in your class, you can sort them into groups:
     • Group of boys and group of girls.
5. Solving Real-Life Problems on Data Collection:
   • You can use data collection to solve real-life problems.
   • For example, if you are planning a party, you might count how many plates, cups, and napkins you need.
   • Another example is counting how many apples and oranges you have to know which one you have more of.

Examples:

• Example 1: Collect data on the number of green and red balls in a box.
  • If there are 8 green balls and 5 red balls, we can say:
    • “Green balls are more than red balls.”
• Example 2: Count the number of boys and girls in your class.
  • If there are 12 boys and 15 girls, you can sort them into groups and say:
    • “There are more girls than boys in the class.”
• Example 3: Count how many apples and oranges you have in the kitchen.
  • If you have 10 apples and 6 oranges, you can say:
    • “I have more apples than oranges.”

By collecting data, arranging it, and comparing different categories, pupils can better understand the concept and use it to solve real-life problems.

Numbers from 1 to 600:

5. Identify Numbers from 1-300 and 301-600:
   • Recognize numbers from 1 to 300, then from 301 to 600.
6. Order Numbers from 1 to 500:
   • Arrange numbers from 1 to 500 in order, starting from the smallest to the largest.
7. Count Numbers 1-600:
   • Practice counting numbers from 1 to 600.
8. Skip Count in 2s, 3s, 5s, and 10s:
   • Count by twos: 2, 4, 6, 8, and so on.
   • Count by threes: 3, 6, 9, 12, and so on.
   • Count by fives: 5, 10, 15, 20, and so on.
   • Count by tens: 10, 20, 30, 40, and so on.

Writing Numbers:

9. Write Numbers 301-600 in Numerals and Words:
   • Practice writing numbers from 301 to 600 in numerals (301, 302, etc.).
   • Also write them in words (three hundred and one, three hundred and two, etc.).

Examples:

• Example 1: Data Collection and Comparison:
  • You count 7 green balls and 4 red balls.
  • You say, “Green balls are more than red balls.”
• Example 2: Sorting Data into Groups:
  • In the class, there are 10 boys and 15 girls.
  • Group the students into a group of boys and a group of girls.
• Example 3: Counting Numbers and Skip Counting:
  • Count from 1 to 20 by twos: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20.
  • Count from 1 to 30 by threes: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30.

By collecting and arranging data, comparing data, and ordering numbers, pupils can improve their mathematical understanding and apply it in real-life situations.

Class Activity Discussion
