Questions and Solutions

Question 1

Flowers of Different Colours: Have you been to a park? What coloured flowers did you see? Were most of the flowers yellow in colour? Look at the different flowers in the picture. Complete the table:

Colour of flowers | Number of flowers

Blue | Red | Orange | Purple

Draw the right flower. Write how many there are.

(a) _____ are the most in number. How many? _____.

(b) _____ are the least in number. How many? _____.

(c) _____ are more than _____

Solution:

Let's analyze the data provided for the flowers in the park.

First, we complete the table with the given number of flowers for each color:

Colour of flowers | Number of flowers

Blue | 9

Red | 7

Orange | 5

Purple | 10

Now, let's answer the specific questions based on this data:

(a) To find which color is the most in number, we look for the largest count in our table. The largest number is 10, which corresponds to Purple flowers.

Purple are the most in number. There are 10 flowers.

(b) To find which color is the least in number, we look for the smallest count in our table. The smallest number is 5, which corresponds to Orange flowers.

Orange are the least in number. There are 5 flowers.

(c) This part asks for a comparison. We can choose any two colors. For example, let's compare Blue and Red flowers. There are 9 Blue flowers and 7 Red flowers. Since 9 is greater than 7, Blue flowers are more than Red flowers.

Blue are more than Red.

Alternatively, we could compare Purple and Orange flowers. There are 10 Purple flowers and 5 Orange flowers. So, Purple flowers are more than Orange flowers.

Common mistakes

  • Misinterpreting the scale of a chart.
  • Incorrectly identifying the highest or lowest value.
  • Errors in counting or tallying data.
  • Difficulty in comparing different categories.

Revision tips

  • Practice drawing simple pictographs for everyday data.
  • Focus on accurately reading the numbers represented by symbols in charts.
  • Review the comparison questions to ensure correct identification of 'more than' and 'least'.
  • Create your own simple charts for hobbies or classroom observations.
