Organize and Represent Data with Up to Three Categories

Students will sort objects or data into up to three categories and represent the sorted data using tally marks, picture graphs, or bar graphs. Students practice labeling categories and recording counts accurately.

How it is taught

0:00 of 1:50

Data is sorted into groups, then shown.

Each bar stands for one category.

Read it: Read it off the bars

You put 7 apples, 4 crackers and 5 ducks on the table. Asking how many more apples than crackers means counting twice. The bars already show it.

Make a stack for each kind: 7 apples, 4 crackers, 5 ducks.
Stand the stacks as bars so you can compare heights.
Read apples 7 against crackers 4: they sit 3 apart.

Recounting the pile for each question works, but it is slow and easy to skip a counter.

A bar keeps the count in view, so you do not have to remember 7, 4 and 5 in your head.

How many more is the gap: from 4 up to 7 is 3, and the bars show that gap.

Stack each count into a bar, then read the answer from the heights.

Guessing from the pile, not the heights, and saying ducks have the most.

Look at how far each bar goes. Apples reach 7, and that is the most.

Who leads in votes? — pizza. Pizza 5, Tacos 1 and Salad 3 — the tallest bar is Pizza.

Sort 9 fruits into apples, bananas, and oranges

Look — we have nine pieces of fruit, all mixed up. Let's sort them!

We'll sort them into three groups: apples, bananas, and oranges.

First, the apples. One, two, three, four apples.

Next, the bananas. One, two, three bananas.

Last, the oranges. One, two oranges.

We write four under the apples.

Three under the bananas.

And two under the oranges.

Now we can see right away — apples have the most!

Grade 1 · Sorting fruits and counting each group

We sorted nine fruits into three groups. Great job organizing data!
