21 – Twenty-one
22 – Twenty-two
23 – Twenty-three
24 – Twenty-four
25 – Twenty-five
26 – Twenty-six
27 – Twenty-seven
28 – Twenty-eight
29 – Twenty-nine
30 – Thirty
31 – Thirty-one
32 – Thirty-two
33 – Thirty-three
34 – Thirty-four
35 – Thirty-five
36 – Thirty-six
37 – Thirty-seven
38 – Thirty-eight
39 – Thirty-nine
40 – Forty
41 – Forty-one

Case Study on Class 1 Mathematics Chapter 8: Numbers from Twenty-one to Fifty
Counting and Ordering Sports Equipment
Background:
Mrs. Johnson is a Class 1 mathematics teacher. She wants her students to develop a strong understanding of numbers from twenty-one to fifty and their application in real-life situations. To achieve this, she designs an engaging activity centered around counting and ordering sports equipment.
Objective:
The objective of this activity is to reinforce the students’ knowledge of numbers from twenty-one to fifty, enhance their counting skills, and develop their ability to order numbers in ascending and descending order.
Procedure:
Preparation:
a. Mrs. Johnson gathers various sports equipment, such as tennis balls, baseball bats, soccer cones, and basketballs.
b. She prepares cards with numbers from twenty-one to fifty written on them.
Activity Steps:
a. Mrs. Johnson sets up different stations, each with a specific type of sports equipment.
b. She distributes the numbered cards randomly among the students.
c. Students are asked to count the sports equipment at each station and match the number on their cards to the appropriate station.
d. They take turns reading the number aloud and placing the card next to the corresponding equipment.
e. Mrs. Johnson encourages students to count aloud and assist each other in correctly identifying and placing the cards.
f. After the initial counting and matching activity, Mrs. Johnson introduces a challenge by asking the students to arrange themselves in a line based on the numbers on their cards, forming an ordered sequence from lowest to highest or vice versa.
g. The students rearrange themselves according to the instructions, and Mrs. Johnson guides and facilitates the process, ensuring that the numbers are placed correctly.
Reflection and Discussion:
a. Once the students have successfully ordered themselves, Mrs. Johnson initiates a class discussion.
b. She asks questions to reinforce the concepts learned, such as “What is the highest number in our line?” or “What comes after twenty-five?”
c. The students take turns answering the questions, promoting active engagement and participation.
Extension Activity:
To extend the learning, Mrs. Johnson provides additional opportunities for the students to practice counting and ordering numbers from twenty-one to fifty. This can include activities like number puzzles, sequencing games, or even creating their own number lines using manipulatives.
