**Understanding Place Value in Two-Digit Numbers:**

Understanding place value is essential for comprehending the value of each digit in a number. In two-digit numbers, there are two places: the tens place and the ones place. The digit in the tens place represents the number of tens, while the digit in the ones place represents the number of ones. For example, in the number 37, 3 is in the tens place, representing 30, and 7 is in the ones place, representing 7. Understanding place value helps in reading, writing, and comparing two-digit numbers accurately.

**Counting and Writing Numbers 21 to 99:**

Counting and writing numbers from 21 to 99 is a crucial skill for students to develop. It involves recognizing and naming the digits in the tens and ones places and combining them to form the complete number. Starting from 21, students count in increments of one until they reach 99. Writing numbers accurately includes placing the appropriate digit in the tens and ones places. For example, the number 45 is formed by combining 40 (four tens) with 5 (five ones).

**Comparing Two-Digit Numbers using Greater Than and Less Than Symbols:**

Comparing two-digit numbers involves determining which number is greater or lesser. The greater than (>) symbol is used to compare two numbers when the first number is larger than the second number. Conversely, the less than (<) symbol is used when the first number is smaller than the second number. For example, in the comparison 36 > 25, 36 is greater than 25. In the comparison, 47 < 53, 47 is less than 53.

**Writing Numbers from 21 to 99 in Words:**

Writing numbers in words from 21 to 99 requires understanding the names of each digit and the rules for combining them. For example, the number 21 would be written as "twenty-one," while the number 99 would be written as "ninety-nine." Writing numbers in words helps develop language skills and enhances the ability to read and communicate numbers effectively.

**Fill up the Tens Frames to Show the Number:**

Tens frames are visual tools used to represent numbers within the range of 21 to 99. Each frame consists of two rows, representing tens and ones. By filling in the frames with counters or drawings, students can visually represent the number based on the place value. For example, to show the number 39, students would fill in three squares in the top row (tens) and nine squares in the bottom row (ones) of the tens frame.

**Practice Exercises for Numbers 21 to 99:**

Practice exercises provide opportunities for students to reinforce their understanding and skills with numbers from 21 to 99. These exercises can include various activities such as writing the numbers in digits and words, comparing numbers using symbols, identifying the numbers before, after, and in between, and solving mathematical problems related to these numbers. Regular practice helps students become more comfortable and confident in working with two-digit numbers.

**Write the Number Before, After, and In Between from 21 to 99:**

Writing the number before, after, and in between involves identifying the sequence of numbers and determining the number that comes before, after, or between given two-digit numbers. For example, the number that comes before 34 is 33, the number that comes after 47 is 48, and the number in between 58 and 60 is 59.

**Maths Games and Coloring Activity for Class 1:**

Maths games and coloring activities provide a fun and interactive way for students to engage with numbers, practice skills, and develop mathematical thinking. These activities can include number recognition games, counting games, puzzles, and coloring sheets that incorporate mathematical concepts. By incorporating games and coloring activities into learning, students can foster a positive attitude towards mathematics and enjoy the process of acquiring new skills.

Overall, understanding place value, counting and writing numbers from 21 to 99, comparing two-digit numbers, writing numbers in words, filling up tens frames, practicing exercises, and engaging in math games and coloring activities help students develop a solid foundation in working with two-digit numbers. These skills are essential for further learning in mathematics and related fields.
