Stem-and-Leaf Plots!

Organize Numbers Like a Plant

Grade 5 Ontario Math πŸ“š β€’ Data Management & Probability

Hello my wonderful Grade 5 superstar! πŸ‘‹

I'm Kashef and today we're learning about Stem-and-Leaf Plots! They’re a clever way to organize numbers so we can see the shape of the data. The β€œstem” is the tens digit and the β€œleaf” is the ones digit. It’s like a plant with stems and leaves! Ready to grow some data? Let’s go! πŸš€

🧠 What is a Stem-and-Leaf Plot?

The stem is the tens place. The leaves are the ones digits listed in order.

Stem
2 | 1 3 4 7
3 | 0 2 5 5 8
4 | 1 6

This shows the numbers: 21, 23, 24, 27, 30, 32, 35, 35, 38, 41, 46

✍️ How to Make a Stem-and-Leaf Plot

  1. Write all numbers in order
  2. Choose the stem (tens digit)
  3. Write the leaves (ones digits) in order next to each stem
  4. Add a key: 2 | 3 = 23

🎯 Let’s Build Stem-and-Leaf Plots!

1. Test scores: 72, 85, 68, 79, 91, 84, 77

6 | 8
7 | 2 7 9
8 | 4 5
9 | 1
Key: 6|8 = 68

2. How many numbers are in the 80s?

2 numbers (84 and 85)
