A Growing Chart

Turn your numbers into a picture

You have counted, measured, and weighed. Wow, that is a lot of numbers! Now let us do the best bit. Let us turn your numbers into a chart.

A chart is a picture made of numbers. It helps you see your mushroom story at a glance. You do not need to touch your kit for this lesson, just your notebook and some colours.

A bar chart of growing

One easy chart is a bar chart. It uses tall and short bars to show numbers. A tall bar means a big number. A short bar means a small number.

Let us make one for how tall your mushroom grew:

• Day 1: 2 cm

• Day 2: 4 cm

• Day 3: 7 cm

Here is how to draw it:

1. Draw a line going up the side. Write 0 at the bottom, then 1, 2, 3, and so on.

2. Draw a line along the bottom. Write Day 1, Day 2, Day 3.

3. For each day, colour a bar up to the right number.

Day 3 has the tallest bar. Your eyes can see the growing right away!

Reading your chart

A good chart answers questions fast. Look at your bars and ask:

• Which day was the tallest? (The longest bar.)

• Which day was the shortest? (The smallest bar.)

• Did the bars go up each day?

When bars get taller and taller, that means your mushroom kept growing. Fun fact: oyster clusters can double in size every day, so your bars often jump up quickly!

Make it your own

You can chart anything you measured:

• How many mushrooms each day.

• How wide the caps were.

• How heavy each harvest was.

Use a different colour for each bar. Add a happy title at the top, like "My Mushroom Growing Chart".

Now you can show your family the whole story with one picture. You are a real mushroom scientist and a maths star. Remember, only your safe kit mushrooms go in your chart, never wild ones from outside. Amazing work finishing Mushroom Maths!
