Grouping & Classification — Group by Use

Joyful Mathematics 2 — Shapes Around Us and everyday-object talk. Grouping by how we use things builds on naming objects around us.

• Objects can be grouped by what we use them for, not how they look.
• Ask: what job does this thing do?
• Things with the same job belong in the same group.

Verbal: Think about the use of each object — to write, to eat, to cut, to wear. Group objects that share the same use.

Symbolic: Pen, pencil, crayon → used to write. Spoon, fork → used to eat. Different use → different group.

Level 1 — Getting started

Level 1 — Practice idea

Look around your school bag — group items by whether you write, cut, or measure with them.

Level 2 — Going further

Some objects have more than one use — a ruler can measure and also draw straight lines. Pick the main use.

Indian real life

At an Indian kitchen, a thali groups spoons and plates for eating, while a knife stays with cutting tools — same idea as grouping by use.

Group these by use: pencil, eraser, sharpener, spoon

Step 1 — Pencil, eraser, sharpener are all used for **writing and correcting writing**
Step 2 — Spoon is used for **eating**, a different job
Step 3 — So pencil, eraser, sharpener form one group; spoon is the odd one by use
Answer: pencil, eraser, sharpener are one group; spoon is different

• Group: comb, hairbrush, toothbrush, spoon — which one does not belong by use?
• Group: umbrella, raincoat, cap — what use do they share?
• Name two things used to write and two things used to eat.

Stretch: List 4 things used for cleaning and 4 things used for writing.

Revision tip: Make a chart with columns: Write, Eat, Cut, Wear — sort objects from your bag into it.
