Where is arrays hiding in ScratchJr garden rows?

Place flowers in rows to prepare for multiplication.

Quick answer

Arrays are hidden in ScratchJr garden rows when you place flowers in equal groups in neat lines and columns. You can use arrays to learn about multiplication and counting in a fun, visual way.

Learning outcome

By the end of this page, you will understand how to make arrays using rows and columns in ScratchJr and how they help you learn multiplication. Success signs:
  • You can make a garden with flowers arranged in rows and columns
  • You can count how many flowers are in each row and how many rows there are
  • You can write a multiplication sentence for your garden array
  • You can explain how arrays help you multiply numbers

Why this matters

Arrays help you understand multiplication in a visual way. When you see flowers in neat rows, you can count them quickly. Arrays are used in real life too – like when you arrange books on a shelf, set up chairs in a classroom, or plant vegetables in a garden. In ScratchJr, you can build your own garden arrays and learn how multiplication works.

How it works

Arrays are made when you arrange objects in equal rows and columns. Think of a garden with flowers:
  • Each row has the same number of flowers
  • Each column has the same number of flowers
  • You can count how many rows and how many flowers in each row
To make an array in ScratchJr:
  1. Choose a flower sprite
  2. Place the flower in a row
  3. Copy the row to make more rows
  4. Count how many flowers in each row and how many rows
  5. Write a multiplication sentence

Examples you can see

Let’s imagine a garden with 3 rows of 4 flowers each.
Row 1 Row 2 Row 3

🌸 🌸 🌸 🌸
This is an array with 3 rows and 4 flowers in each row. How many flowers are there altogether?
  • 4 flowers in each row
  • 3 rows
  • 4 × 3 = 12 flowers
You can also think of it as:
  • 3 rows of 4 flowers = 12 flowers
Real-world example: Imagine you have a pizza cut into 6 slices, and you eat 2 slices each day for 3 days. You can think of this as 3 rows of 2 slices each. That’s 3 × 2 = 6 slices.

Try it as a mini adventure

Adventure: Build Your Own Garden Array! You are a gardener in ScratchJr, and you need to plant flowers in neat rows. Your garden has 4 rows, and each row has 5 flowers.
  1. First, place 5 flowers in the first row
  2. Next, copy the row to make 3 more rows
  3. Count how many flowers are in each row
  4. Count how many rows there are
  5. Write your multiplication sentence: 4 rows of 5 flowers = ? flowers
  6. How many flowers are there in total?
Try to draw your garden array on paper too. Then, use your ScratchJr garden to create a new array with a different number of rows and flowers.

Common mistakes

  • Mistake: Making rows with different numbers of flowers
    Why it happens: You forget that arrays must have equal groups.
    Fix: Make sure each row has the same number of flowers.
  • Mistake: Counting rows instead of flowers in each row
    Why it happens: You mix up what you are counting.
    Fix: Count how many flowers are in each row, then count how many rows.
  • Mistake: Writing the multiplication sentence backwards
    Why it happens: You say "3 rows of 4" but write 4 × 3 instead of 3 × 4.
    Fix: Remember: rows × flowers in each row = total flowers.

Parent and carer guide

To help your child:
  • Ask them to show you how they made their garden array
  • Encourage them to count the flowers in each row and the number of rows
  • Ask them to write a multiplication sentence for their garden
  • Use real-life examples like plates of cookies or toy cars in boxes
  • Be patient if they make a mistake – arrays are a new idea
  • Don’t worry if they don’t get it straight away – it’s a fun way to learn!

Practice questions

  1. How many flowers are in 2 rows of 5 flowers?
  2. How many flowers are in 3 rows of 4 flowers?
  3. How many flowers are in 5 rows of 2 flowers?
  4. How many flowers are in 4 rows of 3 flowers?
  5. How many flowers are in 6 rows of 1 flower?
Answers:
  1. 2 × 5 = 10 flowers
  2. 3 × 4 = 12 flowers
  3. 5 × 2 = 10 flowers
  4. 4 × 3 = 12 flowers
  5. 6 × 1 = 6 flowers

FAQ

What is an array?

An array is a way to arrange objects in rows and columns where each row and column has the same number of objects.

How do arrays help with multiplication?

Arrays help you see multiplication visually. You can count the rows and the number of objects in each row to find the total.

Can I make arrays with anything?

Yes! You can make arrays with flowers, toys, blocks, or even your fingers.

Why are arrays useful in ScratchJr?

Arrays help you understand how multiplication works and make your garden look neat and tidy.

How can I practice arrays at home?

You can make arrays with toys, blocks, or drawings. Try making 3 rows of 4 cookies or 2 rows of 6 pencils.
