Lesson Plan of Comparing and Ordering the Numbers
Subject Mathematics
Grade III
Students` Learning Outcomes
- Compare two numbers using symbols “<”, “>” and “+”.
Information for Teachers
- To show a number less than the other, we use symbol “<” means “less than”.
- To show a number greater than the other, we use symbol “>” means “greater than”.
- To show a number equal to the other, we use symbol means equal to “=”.
- While teaching the lesson, also consult textbook where and when applicable.
Material / Resources
Writing board, chalk/ marker, duster, cut-outs ofr fish
Introduction
- Paste the cut-outs of the fish on board, in front of students.
- Say that this fish is hungry.
- Ask the students; have you noticed anything that shows the fish is hungry?
- Students may respond: “its mouth is open”.
- Encourage the students and reinforce the idea of the open mouth.
- Draw beads on the board to show the two groups of food.
- Now tell the students that fish wants to eat from the groups with more food.
- To show this, demonstrate to the students that how they can choose the cut-outs of fish.
- Ask the students to look carefully at the fish`s mouth and place it in the direction of the beads` group with more quantity.
- With the help of open mouth of fish, introduce the symbols (>) greater than and (<) less than to the students.
- Tell the students that:
-
- Symbol ‘>’ is read as ‘greater than’
- Symbol ‘<’ is read as ‘less than’
- Symbol ‘=’ is read as ‘equal to’
-
Development
Activity 1
- Demonstrate to the students with the help of examples.
- Number having more digits is greater than the number having less than digits.
- Ask the students to compare the following numbers by putting ‘<’ or ‘>’.
Activity 2
- Demonstrate to the students with the help of following examples.
- If the numbers have the same number of digits, than compare the digits at the extreme left in both the numbers to find greater or smaller number.
- Ask the students to compare the following numbers by putting < or >:
Activity 3
- Demonstrate to the students with the help of following examples that.
- If the digits at the extreme left in both the numbers are equal then compare next digit to find greater or smaller number, if they are also equal then we compare the next digit and so on.
- Ask the students to compare the following numbers by putting < or >:
- Ask the students if both the numbers have same digits, what symbol we will use to compare the two numbers.
- After taking their response, tell them that they will use symbol ‘=’ that means ‘equal to’.
- Ask the students to write two 4-digit equal numbers, 5-digit equal numbers and 6-digit equal numbers.
Sum up / Conclusion
- To show a number smaller than the other we use ‘<’ symbol.
- To show a number greater than the other we use ‘>’ symbol.
- To show a number equal to the other we use ‘=’ symbol.
- To check which of the two numbers is greater, e.g. for a 6-digit number, first we check the hundred thousand, then the ten thousands, then the thousands, then the hundreds, the tens and lastly the ones.
Assessment
- Ask the students to compare the following pairs of numbers using symbols <,> or =;
Follow up
- Ask the students to compare the following using symbol <,> or =;
- Ask the students to compare the following using symbol < , > or =;
- Ask the students to solve the questions given in the textbook.
