Questions and Solutions
Question 1
Refer to the provided image containing various shapes.
Count the total number of each type of shape shown in the picture.
After counting, identify which shape appears most frequently and which shape appears least frequently.
Let's count the shapes in the given picture:
First, we identify the different types of shapes present. Based on the typical shapes found in such exercises, we will count triangles and rectangles.
Counting Triangles: By carefully observing the image and counting each triangle, we find there are 7 triangles.
Counting Rectangles: Similarly, by counting all the rectangles in the picture, we find there are 5 rectangles.
Counting Circles: There are 8 circles in the picture.
Counting Squares: There are 2 squares in the picture.
Now, let's compare the counts:
- Triangles: 7
- Rectangles: 5
- Circles: 8
- Squares: 2
The shape that occurs the most is the one with the highest count, which is the circle (8).
The shape that occurs the least is the one with the lowest count, which is the square (2).
Answer: The shape that occurs the most is the Circle. The shape that occurs the least is the Square.
Common mistakes
- Miscounting shapes.
- Confusing similar-looking shapes.
- Incorrectly identifying the most or least frequent shape.
- Difficulty in systematically counting all shapes.
Revision tips
- Practice counting shapes in everyday objects around you.
- Use different colored pens to mark shapes as you count them to avoid errors.
- Focus on clearly distinguishing between different types of shapes.
- Review the solutions to understand the logic of identifying most and least frequent items.
Practice MCQs
Q1. In the given picture, how many triangles are there?
Explanation: By carefully counting the triangles in the provided image, we find there are 7 triangles.
Q2. Which shape occurs the most in the picture?
Explanation: After counting all shapes, the triangle is found to be the shape that appears most frequently in the picture.
Q3. Which shape occurs the least in the picture?
Explanation: By comparing the counts of each shape, the rectangle is identified as the shape that appears the least number of times.
Q4. If there are 8 circles and 5 squares, which shape occurs more?
Explanation: Comparing the numbers 8 (circles) and 5 (squares), 8 is greater than 5, so circles occur more.
