Data Handling

We have learnt, that a collection of objects can be stored out based on their color, shape, size or any other common thing among them. We can organise all the information in a table to understand how many of each item is there in a collection. Information collected is called data.

1. Look at the picture.

Count and write.

(i) How many apples?

(ii) How many watermelons?

(iii) How many bananas?

(iv) How many mangoes?

(v) How many more apples than mangoes?

(vi) Which fruit is greatest in number?

(vii) Which fruit is least in number?

(viii) Are there more apples or bananas?

LIST AND TABLE

2. A list is a record of important items. A shopping list can remind us about what to buy Geeta's mother gave her a list of stationery to buy.

List Pencils 3 Crayons 3 Paint brushes 2 Eraser 1

Check if she has bought everything as per the list.

Is there an item she has forgotten to buy?

We can see pencils, crayons, paint brushes, sharpeners and erasers.

Is there an item that was not on the shopping list?

Let us tally the items with the list. Brushes-check. Pencils-check. Crayons- check. Erasers-check. Sharpener-uh Oh! The sharpener was not on the shopping list.

Is there an item she has bought more or less of?

Let us tally the items in the shopping bag with the list. Brushes-2-correct.

Pencils-3-correct. Crayons-3-correct. Erasers-1-Oh no! Geeta bought one sharpener and two erasers by mistake when the shopping list had no mention of a sharpener and just one eraser.
