Mathematical Signs, Less Than, Greater Than, Equal
Mathematical Signs: Greater Than, Less Than, Equal
We can compare numbers using the signs below.
Watch the video clip below to learn more about the signs.
Activity 1 objects
Try the following questions.
Which symbol would you use to compare the numbers 7 and 9? A) < B) > C) =
What symbol correctly completes the sentence: 6 __ 4? A) < B) > C) =
If 15 is greater than 10, which symbol would you use to compare them? A) < B) > C) =
What symbol should be used to compare 5 and 5? A) < B) > C) =
Which number is greater: 12 or 20? A) 12 B) 20 C) They are equal
What symbol represents "less than"? A) < B) > C) =
If 25 is less than 30, which symbol would you use to compare them? A) < B) > C) =
Complete the sentence: 18 __ 24 A) < B) > C) =

Subject: Mathematics
Objective: Students will be able to compare numbers using the less
than, greater than, and equal signs.
Materials Needed:
1.
Whiteboard or chart paper
2.
Markers
3.
Number cards (0-9)
4.
Worksheets with number comparison
exercises
5.
Small prizes or stickers for
participation
6.
Projector
Teacher's Blogsite
Duration: 60 minutes
1. Engage (10 minutes):
Activity: Start the lesson by displaying three numbers on the board
(e.g., 5, 8, and 5). Ask students which number is the smallest, which is the
largest, and if any of the numbers are the same. Encourage students to explain
their reasoning.
2. Explore (10 minutes):
Activity:
Watch a video clip on the signs in questions
from the teacher’s blogsite. A discussion will ensue as the clip is being
played .Provide each student with a set of number cards (0-9). Have them work
in pairs or small groups to create and compare numbers using the cards. Ask
them to write down the comparisons they make (using <, >, =) on a sheet
of paper.
3. Explain (10 minutes):
Activity: Review the concept of less than (<), greater than
(>), and equal to (=) with the whole class. Use the number examples from the
exploration activity to demonstrate how to use the signs correctly. Write
several number comparisons on the board and explain how to read and interpret
each one.
4. Elaborate (15 minutes):
Activity: Divide the class into pairs again and distribute worksheets
with number comparison exercises. Students will work together to solve the
problems, using the less than, greater than, and equal signs. Circulate around
the room to provide assistance as needed.
5. Evaluate (10 minutes):
Activity: Gather the students back together as a whole group. Review
the worksheets together, discussing the answers and strategies used to compare
the numbers. Ask students to explain their reasoning behind each comparison.
Provide feedback and praise for correct answers and effort.
Complete additional exercises on
teacher’s blogsite.
Extension:
For advanced students or additional
reinforcement, provide a game or online activity where students can practice
comparing numbers using the less than, greater than, and equal signs.
Assessment:
Assess students' understanding of
the concept through their participation in class discussions, their ability to
correctly complete the worksheets, and their explanations of their reasoning
during group activities.
Homework:
Assign additional number comparison
problems for homework to reinforce the concept. Provide opportunities for
students to explain their answers in writing.
By following this 5E lesson plan structure, students will
engage with the concept of comparing numbers using less than, greater than, and
equal signs in a variety of ways, ensuring a deeper understanding of the topic.
