📊 Sorting and Counting
Class 1 Maths · Unit 12 of 12 · about 120 minutes
Children sort objects by one property (colour, shape, size), count each group, and read simple picture charts where one picture stands for one object. They answer questions about which group has the most and which has the least. This unit builds early data handling and prepares children for comparing quantities and simple graphs in later grades.
What your child will learn
- Students will be able to sort a set of objects into groups by one property (colour, shape, or size).
- Students will be able to count the number of objects in each group and say which group has the most and which has the least.
- Students will be able to read a simple picture chart (one picture = one object) and answer questions about the data.
Lessons in this unit
- Sorting Objects: Children sort objects into groups by one property (colour, shape, or size). They say the rule they used.
- Counting Groups: Children count the number of objects in each sorted group and compare the counts to find which group has the most and which has the least.
- Reading Picture Charts: Children read a simple picture chart where one picture stands for one object. They answer questions about the chart: how many in each row, which has the most, which has the least.

What to watch for
- Sorting means putting things in a line, not in groups.
- Help: Show that sorting means making groups of things that are the same.
- The group with the biggest objects has the most.
- Help: Count each group. The group with the highest number has the most, even if the objects are small.
- The row with the biggest pictures has the most.
- Help: Count the pictures. The row with the most pictures has the most, even if pictures are small.
- A group can have objects that are different in the chosen property.
- Help: Ask: 'What is the same about all these? They are all red.'
Try this at home
- Sort a mixed set of shapes by colour: all red ones in one group
- Count red, blue and yellow blocks, one row each; the longest row has the most
- Read a chart of fruits (apples, bananas, oranges)
- Sort a mixed set of objects by shape: all round ones together
Quick questions to ask aloud
- Riya sorted shapes. She put all the circles together. What is her rule? (By shape / By colour / By size)
Show answer
By shape. She put all the circles together, so she sorted by shape. - Riya sorts her shapes. The red group has 🟥🟥🟥. How many red shapes are there?
Show answer
3. There are three red shapes: one, two, three. - True or false: A group with 5 balls has more than a group with 3 balls.
Show answer
True. 5 is more than 3, so the group with 5 has more.
