Definition

What is it?

A Double Ten Frame is a tool used to help count and understand numbers up to 20. It has two rows of five boxes, making a total of ten boxes, and then another identical set of ten boxes right next to it, making it 'double'. This helps us see numbers as 'ten and some more'.

Simple Example

Quick Example

Imagine you have two cricket teams, each with 10 players. A Double Ten Frame is like having two separate scoreboards, each showing 10 spots. If one team scores 10 runs and the other scores 5 runs, you can quickly see the total as '10 and 5', which is 15, by filling up one full frame and half of the second one.

Worked Example

Step-by-Step

Let's count how many samosas we have if we have 13 samosas.

1. **Get your Double Ten Frame:** Imagine two sets of 10 empty boxes.
---
2. **Fill the first Ten Frame:** Since 13 is more than 10, fill all 10 boxes in the first frame. This shows '10'.
---
3. **Count the remaining:** We had 13 samosas, and we've placed 10. So, 13 - 10 = 3 samosas are left.
---
4. **Fill the second Ten Frame:** Place the remaining 3 samosas into the boxes of the second Ten Frame.
---
5. **Read the total:** You now see one full Ten Frame (10) and three boxes filled in the second Ten Frame (3). So, 10 + 3 = 13.

Answer: There are 13 samosas, clearly shown as '10 and 3 more' on the Double Ten Frame.

Why It Matters

Understanding numbers up to 20 easily is a basic skill for all math. The Double Ten Frame helps build a strong foundation for addition, subtraction, and understanding place value. This concept is crucial for careers like banking (counting money), engineering (measuring small parts), or even managing a small shop (keeping track of items).

Common Mistakes

MISTAKE: Students might only use one Ten Frame when counting numbers above 10, getting confused. | CORRECTION: Remember, a *Double* Ten Frame has *two* sets of ten boxes. Use the second frame for numbers greater than 10.

MISTAKE: Filling the second Ten Frame before the first one is completely full. | CORRECTION: Always fill the first Ten Frame completely (all 10 boxes) before starting to fill the second one. This helps visualize '10 and some more'.

MISTAKE: Not understanding that each box represents 'one'. | CORRECTION: Each individual box in the Ten Frame stands for one item or one count. Count each filled box individually if unsure.

Practice Questions

Try It Yourself

QUESTION: How would you show the number 17 using a Double Ten Frame? | ANSWER: Fill all 10 boxes in the first Ten Frame and 7 boxes in the second Ten Frame.

QUESTION: If a Double Ten Frame shows 1 full frame and 4 boxes in the second frame, what number is being represented? | ANSWER: 14

QUESTION: Your friend has 8 marbles, and you have 9 marbles. If you combine them, how would you show the total on a Double Ten Frame? | ANSWER: First, combine 8 + 9 = 17 marbles. Then, fill all 10 boxes in the first Ten Frame and 7 boxes in the second Ten Frame.

MCQ

Quick Quiz

What is the main purpose of a Double Ten Frame?

To count numbers up to 5

To help understand numbers up to 20 by showing '10 and some more'

To learn multiplication tables

Real World Connection

In the Real World

When you buy items at a local kirana store, the shopkeeper might quickly count out 10 items, then count out a few more. This is similar to how a Double Ten Frame works, helping them quickly tally items like 10 packets of biscuits and 3 packets of chips, totaling 13, without having to count each item from 1 to 13 every time.

Key Vocabulary

Key Terms

TEN FRAME: A visual tool with 10 boxes, usually in two rows of five, for counting up to 10 | DOUBLE TEN FRAME: Two Ten Frames placed side-by-side, used for counting up to 20 | PLACE VALUE: The value of a digit based on its position in a number (e.g., in 13, the '1' means ten) | VISUALIZATION: Seeing something in your mind or with a picture to understand it better

What to Learn Next

Great job understanding the Double Ten Frame! Next, you can explore 'Place Value' to see how numbers like 23, 34, or 100 are made up of tens and ones. This will build on your understanding of how numbers are grouped.
