Dot plot of 2, 3, 3, 4, 2, 5, 3, 3, 6; how many are 4 or more

Step by step

The question

Question: draw a dot plot of 2, 3, 3, 4, 2, 5, 3, 3 and 6.

How many are 4 or more?

1 Draw the number line

The number line goes from the smallest number, 2, to the biggest, 6.

2 Put the dots

The first number is 2.

We cross it out, and put a dot over 2.

Next is 3: a dot over 3.

Another 3: its dot goes on top of the first one.

Every number is crossed out, so every number has its dot.

3 Read the plot

Careful!

4 or more means 4 itself counts too.

4: 1 dot.

5: 1 dot.

6: 1 dot.

We add them: 1 plus 1 plus 1 is 3.

So 3 numbers are 4 or more.

4 Check

Let's check: the other numbers make 6 dots.

3 plus 6 is 9, all the numbers.

So it is right!

Let's look back.

First: draw the number line.

Then: put the dots.

Then: read the plot.

Last: check.
